Good day, ladies and gentlemen, and welcome to the quarter-three 2012 Proto Labs Incorporated earnings conference call. My name is Ian. I will be your operator for today. At this time, all participants are in listen-only mode. We will conduct a question-and-answer session toward the end of the conference. (Operator Instructions) As a reminder, this call is being recorded for replay purposes.
I'd now like to turn the call over to Mr. Bill Dietrick, Vice President of Marketing. Please proceed, sir.
Bill Dietrick - VP of Marketing
Thank you, operator, and good morning, everyone. This morning, before the market opened, Proto Labs issued a press release announcing its third quarter and first nine months of financial results for the period ended September 30, 2012. The release is available on the Company's website at protolabs.com.
Before we get started, during the course of this conference call, the Company will provide financial projections and make other statements about its business, including statements about the timing and effect of planned materials expansions in its Firstcut operation that are forward-looking, and are subject to many risks and uncertainties that could cause actual results to differ materially from expectations.
A detailed discussion of the risks and uncertainties that affect the business is contained in the Company's IPO prospectus and other SEC filings, particularly under the heading Risk Factors. Copies of these filings are available online from the SEC or on the Proto Labs website. The Company's projections and other forward-looking statements are based on factors that are subject to change. And therefore, these statements speak only as of the date they are given. The Company does not undertake to update any projection or forward-looking statement.
In addition, to supplement the GAAP numbers, we have provided non-GAAP adjusted net income, and basic and diluted net income per share information that excludes the after-tax cost of stock compensation. We believe that this non-GAAP number provides meaningful supplemental information, and is helpful in assessing our historical and future performance. A table reconciling the GAAP information to the non-GAAP information is included in our financial release.
Now I'd like to turn the call over to Brad Cleveland, President and CEO of Proto Labs. Brad.
Brad Cleveland - CEO, President and Director
Thanks, Bill. Good morning, everyone. Thank you for joining us today on our third-quarter 2012 conference call. With me today is Jack Judd, our Chief Financial Officer. I will begin with a brief overview of our third quarter and first nine months of 2012 financial results, as well as some related commentary. Then, Jack will provide a more detailed look at our financial results, and offer our views on outlook for the fourth quarter. At the end of our remarks, we will be happy to take your questions.
In our just-completed third quarter of 2012, Proto Labs generated record revenue of $32.5 million, a favorable increase of 21% over our very strong third quarter in 2011. Year-to-date, we have generated revenue of $92.4 million, 26% ahead of revenue during the same period in 2011. Thanks in part to our gross margin for the quarter of nearly 61%, we also had record quarterly earnings. Our net income for the third quarter was $6.7 million or $0.26 per diluted share.
The number of customers we have served also continues to grow. From January 1 through September 30 of 2012, we have served 2251 new customers, generating $13.6 million in revenue, and 4394 existing customers generating $78.8 million in revenue. Jack will walk through our record financial results in greater detail later.
Right now, though, I'd like to provide an update on each of our geographic locations as well as our three growth vectors. Our US operations achieved record revenue of $25.6 million during the third quarter or 26% above the same period in 2011. The strong consolidated gross margin for the quarter of almost 61% was in part driven by the excellent utilization of our recent capacity expansions, as well as the efficient use of our labor resources.
Our European operations achieved record revenue of GBP3.7 million, a significant improvement over the second quarter. In US dollars, we generated a sequential increase of $0.7 million or 14% above the second quarter. We believe this sequential growth in Europe is attributable to our ongoing marketing and sales initiatives, and the higher revenue was spread among each of our major markets, including United Kingdom, Germany, France, and Italy. These results were particularly rewarding in the face of the macroeconomic challenges in Europe, as well as their holiday-intensive summer months.
Although our Japanese results are a small portion of our full consolidated results, we are also pleased to report that our third-quarter revenue in Japan was 31% above the same quarter last year, and up 15% sequentially. Over the coming months, we have a number of ongoing marketing, sales and operations initiatives aimed at continuing to accelerate the revenue growth in Japan. And we remain focused on achieving profitability there by the end of 2014.
I'd now like to provide an update on each of our three growth vectors, which include expanding our customer base, broadening the envelope of our service offerings, and developing additional manufacturing services within our Protoworks R&D center. I'm pleased to report that all of these are moving ahead as planned.
Expanding our customer base begins with our ongoing global marketing and sales initiatives that originate in the US, and are customized for cultural and language differences before being rolled out around the world. To optimize our efforts in each of our geographic locations, we temporarily assigned some of our top marketing and sales experts from one area to another as a means of promoting the sharing of ideas, and the distillation and dissemination of best practices.
Over the past year, these exchanges have been between the US and Europe. And for the next year, they will primarily be between the US and Japan, our current area of focus. Our global sales teams also collaborate with each other on key high potential accounts with operations in multiple geographic locations. We are seeing an increasing positive impact from these efforts.
Our second growth vector is to broaden our part envelope. In a manner similar to our worldwide marketing and sales initiatives, our Operations teams also collaborate to improve efficiencies and expand the envelope of parts we can offer to our customers. As suggested in our last earnings call, our Firstcut operation recently announced the addition of several new metals to its offering, including two stainless steel alloys, two low carbon steel alloys, magnesium and copper. These standard industrial metals are now available through our Firstcut and CNC machining service, and provide us with an even greater range of real parts we can custom manufacture for our customers.
Initial orders for these new metals have already begun, and we expect revenue from them to increase gradually. In anticipation of this growth, we have recently ordered approximately $1.5 million worth of associated capital equipment. And it is our expectation that over the course of the next year, these new metals will represent a meaningful amount of our Firstcut revenue.
Next on the list of material expansions will be the addition of some high temperature plastics through our Protomold Instruction Molding service, which we currently believe will be available before the end of the first quarter of 2013.
Our third growth vector is focused on developing and launching additional manufacturing processes. I've often spoken about our Protoworks initiatives, and wanted to let you know that both of our metal molding development projects are making steady progress. Our magnesium fixable molding process is routinely producing demonstration parts that we are shipping to selected customers for their evaluation. And the acquisition and setup of our metal injection molding equipment is underway.
We do not expect a material amount of revenue from these added processes in 2013, but we remain very positive on their revenue possibilities on a longer-term basis. We also have additional research we are working on within Protoworks, and at the appropriate time, we will talk more about it.
I would like to conclude my remarks with a description of why I believe Proto Labs continues to demonstrate the ability to thrive despite ongoing macroeconomic headwinds. In my view, this is due to our breakthrough technology that allows us to serve the ever-increasing need for speed of our very diverse customer base.
Our largest customer is typically only about 1% of our annual revenue. Our market opportunity is large and mostly untapped, and we have an exceptional team of employees who pull it all together. It is the combination of all of these factors that continues to produce gratifying results despite the less than ideal macroeconomic conditions.
On a related note, since our last earnings call, at the request of investors interested in seeing how this is all accomplished, we have created a virtual tour on our website for your use at protolabs.com that has been very well-received by viewers. And I invite you to take a look at our technology enabled manufacturing operations for yourself.
With that, I would like to turn the call over to Jack for a more in-depth review of our third quarter financial results and our outlook for the fourth quarter of 2012. Jack?
Jack Judd - CFO
Thank you, Brad, and good morning, everyone. Revenue in the third quarter of 2012 was $32.5 million, an increase of $5.5 million or 21% over third quarter 2011 revenue. Protomold revenue during the just-completed quarter was $23.5 million, and Firstcut revenue was $9 million. During the quarter, Firstcut revenue represented 28% of total revenue compared to 26% during the third quarter of 2011.
Our international revenue was $7.6 million or 24% in total revenue during the third quarter of 2012, compared to $7.5 million or 28% of revenue during the same period in 2011. During the quarter, our revenue was negatively impacted by changes in currency exchange rates by approximately $100,000. On a year-to-date basis, this number is approximately $300,000. Year-to-date revenue was $92.4 million, an increase of $19.1 million or 26% over 2011 revenue. Year-to-date, international revenue was $22.5 million, an increase of 21% over $18.6 million in 2011.
Our increases in revenue were driven by both new customer acquisitions and increased orders from our existing customers. Year-to-date, we have now done business with 2251 new customers, generating $13.6 million in revenue, and 4394 existing customers, generating $78.8 million in revenue. This compares to 1965 new and 3162 existing customers, generating $13.1 million and $60.2 million in revenue, respectively, in the nine months of 2011.
New customer growth is up 15% over 2011. Our gross margin in the third quarter of 2012 was 60.7% compared to 61.7% in the same quarter in 2011, and 59.1% in the second quarter of 2012. Our operating income was $9.6 million or 29.5% of revenue in the third quarter. Year-to-date, our operating income is $24.7 million or 26.7% of revenue. Operating expenses were $1.3 million higher in the quarter than the previous year. This increase was mostly driven by the addition of 31 new employees in marketing and sales, and $1.8 million in additional spending in R&D that includes our Protoworks initiatives.
Companywide at the end of September, we had 610 total employees. This compares to 474 and 511 at the end of September and December 2011, respectively. Our diluted earnings per share in the third quarter of 2012 was $0.26 per share. Adding back the after-tax cost of stock compensation, our non-GAAP diluted earnings per share in the quarter was $0.29. Our reconciliation of net income and EPS to non-GAAP net income and EPS was included in our earnings release this morning.
At the end of September, our cash and investments totaled $88 million. Our capital spending so far in 2012 totaled $14.4 million, almost all of which was spent on factory expansion, and additional CNC mills and injection molding presses.
I would now like to provide some guidance into our projected results for the remainder of 2012. We currently expect revenue in the fourth quarter to be between $31 million and $34 million. Stock compensation costs in the fourth quarter will be approximately $700,000. Our tax rate will be similar to the just-completed quarter. Taking all of the above factors into consideration, our quarterly non-GAAP EPS, adding back the after-tax cost of stock compensation, is expected to be between $0.24 and $0.28. Our full-year CapEx in 2012 is expected to be approximately $16 million.
That concludes our prepared remarks. Operator, we will now open up the call for questions.

(Operator Instructions) Troy Jensen, Piper Jaffray.
Troy Jensen - Analyst
Congratulations on a great quarter, gentlemen.
Brad Cleveland - CEO, President and Director
Thank you, Troy.
Troy Jensen - Analyst
So can we dive in a little bit on the metals here? So first of all, in the Firstcut business, $9 million this quarter, how much of that do you think is aluminum versus plastic?
Brad Cleveland - CEO, President and Director
I think it's around half and half.
Troy Jensen - Analyst
Okay. And when you think about the introduction of steel, copper, and magnesium here, I'm assuming all that's Firstcut?
Brad Cleveland - CEO, President and Director
Yes.
Troy Jensen - Analyst
What's -- and you talked about more material contributions. But I mean, how long before these new -- I assume steels may be bigger of the three. But can you just give more color on what you mean by material contributions? And can steel and copper and magnesium catch up to the level that aluminum is currently?
Brad Cleveland - CEO, President and Director
Yes, this is Brad. We were actually pretty impressed that as soon as we turned it on, before we even announced it, we started getting a significant number of requests for quotes. So, we're very optimistic.
And stainless steel, by far, is the number one most requested metal that we haven't done up until recently. So, I think it will be very significant. But nobody's ever been able to do quick-turn stainless steel before, so we're not really completely certain how big the demand for it is. We just know it's going to be very significant.
So we'll see if grow gradually over the course of the next year. And we'll look back and see what fraction it is. My guess is, it won't be as big as aluminum, but it's really too soon to tell.
Troy Jensen - Analyst
Okay, probably the second highest metal. Then of the two, copper and magnesium, which one do you think is going to be bigger?
Brad Cleveland - CEO, President and Director
I don't think we have a good sense of that yet. Nobody's been able to do that very fast before, either. So we will see. We have a number of customers that are very interested in both.
Troy Jensen - Analyst
Okay. And then one for Jack here. Operating margins non-GAAP were 31.8%, I believe?
Brad Cleveland - CEO, President and Director
Yes.
Jack, I think you talked about having a business model target here of 28%-plus. I mean, where do we go from here? It seems like I guess I would assume that with revenue growth and scale, you guys should be able to expand margins. But just wondering if you have any thoughts on an operating margin target?
Jack Judd - CFO
I appreciate the fact, Troy, that you recognize that we have outstanding operating margins. We sure had a nice P&L in this just-completed third quarter. And I think that it shows how well this business can perform when revenue comes in at expected or above expected levels, and our team does an excellent job of controlling costs. And we get great productivity out of our factory.
I don't think I would want to sell, at this point anyway, that margins would grow from what they were in the third quarter. But we sure like it when they come in, and we sure hope that they continue that way going forward.
Troy Jensen - Analyst
Right, I suppose you've got some investments here with the metal stuff. But last one and I'll cede the floor. Just can you talk about the new customers were great this quarter. What do you think is working best on the sales and marketing effort to attract so many new customers?
Brad Cleveland - CEO, President and Director
This is Brad, Troy. You know, we haven't introduced any dramatically new or different marketing initiatives in the last quarter. But I would say that what this proves is that our very aggressive ongoing direct marketing campaigns worldwide continue to be very well-conceived and executed. And we couldn't be happier with the leads that they generate for our sales organization.
And then with respect to our sales organization, I think Jack mentioned that we've been scaling that up. And we have exceptional organizations in the United States and Europe and Japan. And we have a lot of really cool initiatives going on. I mentioned one thing in the prepared remarks about coordinating global accounts is going on between the United States and Europe right now. And I'm really excited about that.
And we also have a focus on larger accounts, companies that not only are global, but are very large in size. And we believe very strongly that we've barely begun to tap that market. So I think if you add all of those things together, that's a great explanation of why, not only are we generating new customers, but our existing customers' business is growing as well.
Troy Jensen - Analyst
Well, gentlemen, keep up the good work.
Operator
Brian Drab, William Blair.
Brian Drab - Analyst
Congratulations on a great quarter. First question is, in the second quarter, you were down sequentially in Europe, and this quarter up materially. Can you talk about the top one or two things that you saw play out differently in this quarter or drove demand more in the third quarter in that region than the second quarter?
Brad Cleveland - CEO, President and Director
Brian, this is Brad. You know, we didn't have any specific initiatives that were any different than the normal way we do business. I would say that our colleagues in the UK and in Germany and in France continue to work very hard with our very aggressive marketing and sales techniques, to find new customers and sell more to existing customers. And those efforts simply are paying off.
Brian Drab - Analyst
Okay. All right. And if my numbers are up to date here on the model, it looks like your revenue per existing customer is down in 2012 year-to-date compared with 2011. First of all, is that correct? And could you talk about why that might be?
Jack Judd - CFO
Are you doing a comparison of revenue per existing customer for all of 2011 versus year-to-date in full-year 2011 versus nine months of 2012?
Brian Drab - Analyst
Yes. I'll just tell you the numbers that I'm using. You gave us the 4934, the total existing customers year-to-date in 2012, and revenue per existing -- revenue from existing customers of $78.8 million, so I get $16,000 per existing customer?
Brad Cleveland - CEO, President and Director
Yes, those numbers need to all -- if you're going to do comparisons, they may need to be measured on the same period to same period.
Brian Drab - Analyst
No, I understand that. So those are my numbers for 2012 year-to-date. Right? 4.9 -- 4900 existing customers, revenue of $78.8 million, $16,000 per existing customer. My existing customer count last year is [3.2 thousand, 61 million] from those customers and revenue per customer [19.4 thousand]. So I have it going from [19.4] down to [16] and I wonder if that's correct? And if so, why is that?
Jack Judd - CFO
I don't have all the exact numbers in front of me, Brian, but I think they always need to be looked at for comparison purposes at the end of the year, because of the vagaries that can happen from quarter to quarter. And so I guess if I'm going to hold any comments or say any comments about whether those numbers are moving or whether there's any significance in it, I would want to comment after 12 months' worth of data.
Brian Drab - Analyst
Okay. Okay. I'll follow-up with you more on that later. And then Jack, is the $1.5 million related to equipment for -- to accommodate new metals, is that incremental to your previous CapEx forecast? Or was that expected?
Jack Judd - CFO
It was somewhat expected in what we said in the third quarter. And the $1.5 million is almost all to support hard metals.
Brian Drab - Analyst
Okay, great. I'll get back in line. Thanks.
Operator
Steve Dyer, Craig-Hallum.
Steve Dyer - Analyst
Good morning, guys, and congratulations on the results. Just Jack, I think I missed new customer adds in the quarter. Could you repeat those?
Jack Judd - CFO
Why don't you let me get that number back out, and I will -- you ask another question and I'll get back to you on that one.
Steve Dyer - Analyst
Sure. Just with respect to gross margins, this is kind of 60-plus is a number that's reflective of very -- pretty high capacity. I can't imagine you're anywhere close to capacity, given the Rosemount expansion. And I know you don't like to give out an exact number, but how should we think about that? I mean, can that number work higher? I would think there's a fair amount of capacity left.
Jack Judd - CFO
I think it's important to look at our capacity from both the square footage of our floor space, for which we have a lot of capacity yet to use. And then you could look at the capacity of our equipment and our employees. And we always talk about that. We run a lot tighter.
We expand our capacity with people and equipment every quarter. And so, this past quarter when our margin popped up, I think that it's indicative that we ran much closer to our capacity than we had in the first and second quarters, when our gross margin was below 60 points.
Brad Cleveland - CEO, President and Director
Let me add one thing to that. Not only do we manage capacity on square footage and on equipment and people, another way to slice it is we manage capacity on Protomold versus Firstcut. And within Firstcut, we manage capacity on plastics versus metals. And within metals, we manage capacity on soft metals versus hard metals. And we also split it all the way down either in the United States and Europe and in Japan. So, there are about 12 different types of capacity that we manage on a real-time basis.
Steve Dyer - Analyst
All right, understood. That's helpful, thanks. And then, secondly on operating expenses, very good discipline in the quarter. R&D seems to be running at a level less than maybe you had signaled a couple of quarters ago for the Protoworks expansion. How should we read that going forward? Is that sort of there's going to be a little delayed spending? Or are you just finding that you don't need to spend as much as maybe you thought?
Jack Judd - CFO
I think the most that we spent in the third quarter probably is very close to what we thought we were going to spend in the third quarter, back in May, when we did -- when we talked about Protoworks for the first time. I think that R&D spending will go up incrementally quarter-over-quarter. I don't see any large one-time increases in it in the near future.
Steve, for the first nine months of this year, we've done business with 2251 new customers in 2012.
Steve Dyer - Analyst
Okay, thank you. One last question and then I'll hop back in the queue. Are you seeing anything new in the competitive environment at all? There seems to be obviously a lot of buzz in the last six months about quick-turn parts and 3D printing and how all of it fits together. You seeing anything new there?
Brad Cleveland - CEO, President and Director
This is Brad, Steve. The short answer is no. The slightly longer answer is, as far as 3D printing and additives, it remains our position that we are very complementary and synergistic with those technologies. And I've spoken at length about why that is the case, and I'll be happy to do that again, if someone is interested. And in terms of conventional competitors, it remains true that we still have no significant conventional injection molding or machining competitor in the world that we run into every day.
Steve Dyer - Analyst
Great. Thanks. Keep up the good work, guys.
Operator
Peter Misek, Jefferies.
Peter Misek - Analyst
Maybe you gentlemen can walk through the dynamic that we saw during the quarter. I think the results are particularly impressive when we see that we have a fiscal cliff in the US, continued European weakness, et cetera. Was there any sort of order changes during the quarter? Was there some kind of pattern that you saw emerge that you see bottoming out in August, an acceleration in September?
The Chinese PMI -- you know, help us out. Can you help us understand that? Because the trajectory that appeared to be exiting last quarter and through the summer, obviously, wasn't this strong. And then you guys hit the ball out of the park now. Maybe you can help us understand what the order patterns looked like during the quarter?
Brad Cleveland - CEO, President and Director
Yes, this is Brad. You know we just focus on our business. And we don't have customers coming back to us talking about China or talking about the macroeconomic conditions anywhere.
We recently looked at the number of quotes we do every day, and we're doing like 1000 quotes a day at the moment. And it's obviously rising over time. While we do have the ability to look at the data, the quotes, and we can see that in the second quarter and a little less than the third quarter. It took customers a little longer to make decisions and so on.
So when we talk about macroeconomic conditions, our customers don't talk about that. They just talk about their projects. They just want their parts. What we think is that when we look at the data and we see that customers are taking a longer time to make decisions, we assume that's due to the fact that they have economic pressures on their businesses that they're dealing with. And we just continue to focus on executing on our strategy.
And all I can say is the second quarter was good. The third quarter was better. But we're used to setting records. It's a very normal occurrence in this Company.
Peter Misek - Analyst
Well, in terms of as we look forward, you talked about buying another $1.5 million of capital equipment. Given what you accomplished this quarter and given the introduction of new metals, should we consider that if those new metals take off stronger than we would expect, we would expect a CapEx increase early next year? Would that timing makes sense? Or at some point in the middle of next year?
Jack Judd - CFO
I think we've given guidance that we expect CapEx to be 8% to 12% of revenue. And really I see nothing that would indicate that it won't still be that next year. And of course, most of that equipment will be for mills, for both plastics, metals, hard metals and injection molding presses.
Peter Misek - Analyst
All right. I guess the thing I'm trying to tease out -- that's a reasonably wide range. Should we be assuming that, given the execution, we should be at the higher end and we're trying to get trajectory here more than anything?
Jack Judd - CFO
We'll know better whether it's at the high end or the low end as we go through this fourth quarter, and we do our projections for all of 2013. For right now, I'd just as soon say that it will be between 8% to 12%, and we'll give you an update in February at our next earnings call.
Peter Misek - Analyst
And then my last question, in terms of free cash flow, I mean, these results obviously are going to lend themselves to some pretty nice cash flow here. And I would have -- I would assume as you continue to set records, if that will accelerate. Is there any defined plans aside from CapEx that you guys are thinking about what to do with the money, capital plans looking out for next year and beyond? Should we be considering return of capital? Should we be considering after expense? And how should we be thinking about that? Thank you.
Brad Cleveland - CEO, President and Director
We're very happy with how the business is generating cash. And as we've talked about in the past, we're going to let it sit on our balance sheet. We're not even one year out from our IPO. And if we have some really good ideas on how to use the cash, we'll talk more about it in the future. But for right now, it's going to just sit right on the balance sheet.
Peter Misek - Analyst
Perfect. Thank you, gentlemen.
Operator
Greg McKinley, Dougherty & Company.
Greg McKinley - Analyst
Nice results. A couple of quick questions. Capacity utilization goals. I mean, there's obviously a sort of tug-of-war between delivering really strong margins and still making sure you have the availability to deliver one-day turn times, if your customers require it of you. Can you just remind us how you think about that? And where you may -- where you sort of see the ceiling on capacity utilization, given the flexibility you need to have for your rapid turn business?
Brad Cleveland - CEO, President and Director
Yes, Greg, this is Brad. Yes, if you heard a little bit earlier, I was talking about all the different ways we look at capacity around the world, our different services, our different materials and so on. And we often say that when we start to get close to 80% in any one of those 12 different measures, we start to get nervous.
So, yes, we have, on a daily, weekly, even monthly to some extent, we have a significant amount of variability in our orders, obviously, because some customers get into a real crunch that they need us to help them with, which is why we're here. So we always need to have capacity for those very, very quick-turns. And our customers pay us for that.
So I'd say the general rule of thumb we have is about 80%, but sometimes when we see a growing demand for something like these new Firstcut metals, we might move a little bit more aggressively than that. 80% is a pretty good guesstimate.
Greg McKinley - Analyst
Okay, thank you. And then, Brad, you talked about commercializing a higher temperature plastics offering within Protomold potentially, I guess, Q1 of '13. Is there any framework you can give us to understand what you guys assess the market potential of that to be, relative to the markets you're currently serving with Protomold?
Brad Cleveland - CEO, President and Director
It will be small relative to the overall Protomold size today. There are a number of plastics that can be molded but require steel tools instead of our standard aluminum tools. Part of our metal molding initiatives we've gotten very, very good at making steel tools and very quickly. And that will allow us to add half a dozen different plastics. But we do hundreds today.
Greg McKinley - Analyst
Okay. And then, Jack, finally, just following up on the customer account data, wonder if you could just remind me what were your year-to-date customer accounts existing and new and related revenues for the nine-month period last year? Just so I have a good comp.
Jack Judd - CFO
The new customer count was 1965 doing $13.1 million, and 3162 existing customers doing $60.2 million.
Greg McKinley - Analyst
Okay, perfect. Thank you. Nice quarter.
Operator
Zach Larkin, Stephens.
Zach Larkin - Analyst
Congratulations on a great quarter. First off, Brad, I wondered if you could talk about with the new metals that you've introduced, the stainless steel and everything, I know we're very new into that, but have you seen any differences in the industries or potential applications that these orders are coming from? Any commentary there would be helpful.
Brad Cleveland - CEO, President and Director
Well, the little bit that we know so far is that we have a lot of interest in those metals from all the same industries that are currently buying plastics and aluminum from us. I think probably the most common industry that we do business with is something having to do with medical. And we have a lot of -- hundreds and hundreds of medical-oriented customers who have shown an interest in stainless steel. They also do aluminum. They also do a lot of different plastics. But for the most part, we serve every industry that uses plastic or metal parts and that's almost every industry.
Zach Larkin - Analyst
Thanks for that. And then, Jack, as you look out to the 4Q guidance, can you give us a sense of what types of assumptions are underpinning that guidance, maybe from a margin standpoint?
Jack Judd - CFO
I expect margins could drop back just a fraction because we will probably add some level of people preparing for 2013. But all of our -- you know, the EPS guidance I gave anticipates all of those little things that can happen. We do anticipate that Europe will continue to see some headwinds in that number. So we're not -- we're conservative with Europe, as I think would be proper.
Zach Larkin - Analyst
Okay. And then I think in the prepared remarks, the data from a geographic standpoint, we had the US but then Europe was given in pounds. Could we get just kind of US, Europe, and other, broken out in dollar values?
Jack Judd - CFO
I don't have that information with me right here. I know that we said it in pounds because of currency exchange. So, it was not a record in dollars. It was a record in pounds. So I think in Europe, it was down just very slightly year-over-year. But I don't have those numbers. I'm sorry.
Zach Larkin - Analyst
Okay. All right. Thank you very much.

Tom Hayes - Analyst
Congratulations on the quarter. Just a question on Europe. On the last call, you had mentioned slightly or moderating ramp-up in the sales force. I'm just wondering of the 31 people that you had in the quarter, how many were positioned in Europe? And as far as maybe you can give us a little insight as to your ramp-up expectations over the next couple of quarters for adding in Europe.
Jack Judd - CFO
I think the 31 number is not in the quarter. It's over the -- from a year ago. So we've added 31 in a year, so it gives you an idea of the increased cost. I don't have exactly how much is, but the majority of people we've added have been sales and marketing in the US. You know, there's probably been half a dozen or eight that had been added overseas in the period of time.
Tom Hayes - Analyst
Okay. And then just to confirm that, you mentioned when you were talking a minute ago, as far as your CapEx target, is that 12% of revenue? Did I hear that right?
Jack Judd - CFO
Our CapEx target will generally be between 8% to 12% of revenue. And like this past year, we've spent an awful lot of money on facilities expansion. And so when we do that, when we buy a building or something, it might pop above 12%.
Tom Hayes - Analyst
Okay. And then just lastly, I was just wondering if you could maybe talk -- is there any material margin difference between, let's say, the business in Europe and the business in the US?
Jack Judd - CFO
I'm sorry, could you repeat that question again?
Tom Hayes - Analyst
Yes, is there any material margin difference in the business that you're doing in Europe versus in the US?
Jack Judd - CFO
No. The margins are very similar. The P&Ls look very similar between the two markets overall, in terms of the cost that it does to do sales and marketing and all the other functions -- very similar.
Tom Hayes - Analyst
Great. Thank you.

Another question on the new metals. I was wondering if you might be able to give us some sense in terms of what ASPs are like versus maybe your other products in Firstcut? And is there much of a difference in terms of the margin profile on these products?
Brad Cleveland - CEO, President and Director
This is Brad. Stainless steel will be more expensive than aluminum. We have also a lot of very expensive plastics that we purchase for our customers. But the new harder metals, most of them will be significantly more expensive than aluminum. And the actual price, of course, depends upon the geometry of the part and whether or not the customer is buying the quick-turn. Margins we expect to be comparable to all of our other materials.
Jim Ricchiuti - Analyst
Okay. And with respect, Brad, to some of the colors you provided on Japan, it looked like you had a pretty solid quarter there. And I'm wondering if the trends you're seeing there are sustained, would that put you ahead of schedule in terms of your 2014 goal? Or do you feel like you're basically on schedule? The point I'm trying to get to, I guess, is if these trends continue over the next couple of quarters, it sounds like you're encouraged by what you're seeing.
Brad Cleveland - CEO, President and Director
Yes, we're encouraged, but I'll stick to the 2014 profitability objective.
Jim Ricchiuti - Analyst
Okay. Thanks a lot.
Brad Cleveland - CEO, President and Director
Sure. Thank you.

So, a couple, most of mine have been answered. But I want to go back to the question on margins that was asked. I mean, why can't margins grow from here? Is -- would you say the low 30s is the structural ceiling on this business? Or is it because you're investing so much for growth?
Jack Judd - CFO
Well, Nicole, it's a good question. And I think, overall, we're trying to say that we're a revenue growth story. We love our margins. We think that they ought to be noticed by investors for how unique they are and how high they are. But we're not trying to constrain our engine that might constrict growth, so that we can get another 1 point of operating income. But I do think over the coming years, is that we should see higher margins than we'd have the past two or three quarters.
Nicole DeBlase - Analyst
Okay. That's fair. Thank you. And I'll ask one more. So how do you guys approach the larger account opportunity? And how is it different than how you approach smaller customers? Is there a big difference in how your sales and marketing employees go after larger customers versus smaller customers?
Brad Cleveland - CEO, President and Director
Yes, Nicole, this is Brad. Yes, there's a pretty significant difference. When we're going after the very large accounts, whether it's, let's say, just domestic or the global accounts, where we're coordinating between our salespeople and the United Kingdom and the United States, there's a significantly different approach, where we might go off and, let's say, do a seminar for 400 engineers at a major automotive company, which we did recently. Or we might create specific marketing and sales campaigns aimed at folks who might be in jobs like Director of Engineering.
And that is something we've just begun in the last few years and we're ramping that up. Historically, we've been very much a grassroots marketing and sales organization. And so we believe, and I think we're showing, that the combination of the two strategies can be very effective.
Nicole DeBlase - Analyst
Okay, great. That's really helpful. I'll stop right there, but congratulations on a great quarter.
Brad Cleveland - CEO, President and Director

Yes, just a couple more questions, I think. I don't know that you've commented on this yet, but inventory is up quite a bit from last year's levels. Can that be primarily attributed to holding new materials and inventory to broaden the product envelope?
Jack Judd - CFO
Our inventory would be up because of the tungsten carbide that we bought for end-mills. We were worried that we would have a supply shortage of that. And so we bought some in advance, and the shortage never occurred. And so we'll be taking that down over the next year. It's not because of new materials.
Brian Drab - Analyst
Okay. What was that material? It is a material -- tungsten -- can you just elaborate on that? It's tungsten carbide (multiple speakers) for the --?
Jack Judd - CFO
(multiple speakers) Go back to Brad.
Brad Cleveland - CEO, President and Director
Yes, this is Brad. Tungsten carbide is the material that our end-mills are made out of. End-mills are the drill bit-like components that cut parts.
Brian Drab - Analyst
Right. Right.
Brad Cleveland - CEO, President and Director
And there was some news out there that there might be a shortage on that maybe a year ago. And so we bought a bunch of that, and the shortage ended up not occurring. So we'll be working our way through that now.
Brian Drab - Analyst
Okay, when you buy those tungsten -- when you buy that tungsten carbide, is that in the form of a drill bit already? Or is it something that you customize in-house?
Brad Cleveland - CEO, President and Director
It's something that we send out to have manufactured for us. We just wanted to make sure that we have that raw material.
Brian Drab - Analyst
Okay, great. And last quarter, Brad, you gave us a little bit of clarity on how things trended during the quarter. And specifically, you said that in the second quarter, things -- demand started out kind of average, then it softened a bit, and then strengthened toward the end of the quarter. Can you make -- give us a similar assessment of how the third quarter played out?
Brad Cleveland - CEO, President and Director
Sure, I would say there wasn't anything particularly noteworthy about any of the months. They were all fairly strong.
Brian Drab - Analyst
Okay, thanks a lot.
Brad Cleveland - CEO, President and Director
Sure.

Troy Jensen - Analyst
Just one follow-up. Last year in the December quarter, you guys were down almost 5% sequentially, and this quarter, midpoint of your guidance is flat. So I know you guys have limited visibility. I mean, it's just your business model. But what gives you confidence that this year is going to be so much better than last year?
Jack Judd - CFO
I think we're coming off of a strong third quarter, so that's one of the reasons why we think that it can be better. And we certainly have an awful lot of sales and marketing initiatives that we believe in, that have historically provided a lot of leads and a lot of quotes, and eventually orders. And so I think it's confidence in our business.
Troy Jensen - Analyst
All right. Well, good luck, gentlemen.
Brad Cleveland - CEO, President and Director
Thanks, Troy.
Operator
Okay, thank you, Troy. We have no further questions in the queue at this moment in time, gentlemen.
