Renishaw to Introduce Additive Manufacturing System Aimed at Production

Renishaw has announced that it is developing a new additive manufacturing system designed and engineered specifically for production manufacturing. The machine, which the company has provisionally named the “EVO Project,” includes a 500-W laser, high-capacity filtration and automated powder handling.

Renishaw became an additive manufacturing OEM through acquisition in 2011. Now, this new machine will be the first the company has designed and engineered in-house, drawing on its own knowledge and background in production manufacturing. The new machine does not replace the Renishaw AM250 system, the company says, as this existing machine remains better suited for flexible manufacturing and research applications in which changes between materials are a requirement.

The new machine, by contrast, is designed for single-material industrial production. Powder handling is said to be almost entirely hands-off, while powder recirculation, recycling and recovery are all carried out within the inert atmosphere of the system.

Renishaw plans for the new machine to be available during the second half of 2015. Learn more here

3D Systems to Acquire CAD/CAM Company Cimatron

This photo from 3D Systems’ booth at EuroMold shows one of the company’s desktop 3D printers. The company also supplies additive manufacturing machines for metal parts as a result of an acquisition last year.

Additive manufacturing technology provider 3D Systems announced this week that it reached an agreement to acquire CAD/CAM software company Cimatron. Cimatron’s products include CimatronE software and GibbsCAM.

The move is the first example I can recall of a company with product lines aimed entirely at CNC machining being acquired by a company that grew up in the 3D printing space. (But see Arcam’s recent acquisition of machining supplier DiSanto.)

My colleague Matt Danford of MoldMaking Technology magazine is at the EuroMold show in Frankfurt, Germany, this week. In 3D Systems’ booth at this show, Matt had the chance to speak with Tom Charron, the company’s VP of product marketing, about this move.

3D Systems is “expanding beyond purely additive,” Mr. Charron says. He cites Cimatron in the context of other recent acquisitions by the company, including design and scanning software Geomagic. “It's all about the entire value proposition for manufacturing.”

He says, “The reality is that in five years additive will not be a novel technology off in the corner somewhere. It will be right in the middle of the production floor alongside CNC machines.” Cimatron therefore addresses the company’s ability to serve “the non-additive side of digital fabrication.”

Hiring Consultant Shares How to Evaluate Soft Skills

Tony Staub (left) has dramatically changed what he looks for in evaluating machine-shop employees. At the two links in the text below, find our original article describing the shop owner’s change, and also read some additional insights provided by the hiring consultant Mr. Staub works with.

Readers of our recent article describing Staub Machine’s change in hiring philosophy—the shop now hires for personal strengths instead of aiming for metalworking skills—asked about the role of the consultant mentioned in the article. The consultant, whom the article does not name, helps this shop evaluate prospective hires for attributes such as communication ability and the capacity to learn.

His name is Patrick Crotty. The firm he founded is PXC Associates in Orchard Park, New York. He works with various manufacturers on recruitment, and he says the place to evaluate candidates’ soft skills is in the interview. Most hiring managers dislike interviews and have too little experience with them, he says, so they end up doing most of the talking. I recently reached out to him, and he shared these thoughts on evaluating prospective manufacturing employees.

In Case You Missed It: Additive Manufacturing's November 2014 Digital Edition

The cover story of the November issue of Additive Manufacturing places AM into the context of an even larger idea. Lockheed Martin Space Systems is aiming to achieve what it calls the “digital tapestry,” a vision for manufacturing that avoids unnecessary effort and interpretation by keeping all manufacturing information in the digital realm. Additive manufacturing, because it can directly manifest a design conceived through digital collaboration, is valuable to realizing this ideal. Also in this issue, metal and plastic part maker Harbec Inc. describes how it uses AM alongside other manufacturing processes. The digital edition of this issue is available now. To subscribe to Additive Manufacturing, go here.

Acquisition Brings DMLS Capability into M2M Group

Generation Growth Capital Fund is an investment group managed out of Milwaukee and Chicago that aims to develop the unrealized value of small- to mid-size manufacturing businesses. We first wrote about the fund here. The firm has sought to acquire contract manufacturing businesses featuring both attractive machining capabilities and strong customer relationships in important markets. As of the beginning of this year, it had integrated four such machine shops into a multi-site manufacturing organization called the M2M Group.

As a whole, these four formerly independent shops provide capabilities that range through large-part machining, micromachining, multitask and five-axis machining, and rapid prototyping of both machined parts and castings. Bringing these companies together into one group enables them not only to leverage one another’s resources, says Generation Growth Capital Fund managing director John Reinke, but also to realize efficiencies by adopting an organization-wide set of best practices and sharing certain quality, management and back office expenses. The aim, he says, is to build a contract manufacturing organization able to serve OEM customers throughout the entire manufacturing process from early prototyping to mature production. Until recently, though, there seemed to be a piece missing.

Mr. Reinke says, “The thing keeping me up at night was: What’s going on with additive manufacturing?”

Now, the M2M Group will discover the answer to that question. The fifth company to be acquired into the group is Atlantic Precision Inc. (API) of Port St. Lucie, Florida, a machining business that also additively manufactures metal parts through direct metal laser sintering, or DMLS.

That API became available for acquisition was a welcome development, Mr. Reinke says. The company was already known to his group. M2M company Tri Aerospace had active projects with API and a track record of working with this company for metal prototype parts and short-run production runs, particularly for the jet engine industry. Before API was a candidate to be bought, Mr. Reinke had been searching for the way to add additive manufacturing of metal parts to the M2M stable, and the findings of his search say something about the state of additive manufacturing as a production option today.

In general, he says, the companies he found were just starting out. It was difficult to find an additive manufacturing provider of the right size to be acquired by his fund that was anything more than a recently launched or recently reinvented company. Through acquisition, he hoped for the M2M Group to avoid the learning curve of additive manufacturing, but what he consistently found were companies going through that same learning curve themselves. Therefore, he had all but resolved to launch additive manufacturing as a green-field project within one of the existing M2M businesses.

Then the group heard from API. The company is distinctive for the length of time it has offered additive manufacturing services to industrial customers, he says. To an extent, at least, it has been through the learning curve.

And it has been through this curve alongside customers. This is also key, he says. The trial-and-error requires customers who are willing to go through the process along with the supplier. API has the customers who had that willingness, and as the result of working closely together to make important strides forward in understanding additive manufacturing, API now has particularly strong customer relationships.

One anecdote illustrates how quickly events are moving related to this method of making parts, Mr. Reinke says. While the acquisition was under way, a customer asked API to purchase another DMLS machine so the shop would have additional capacity for upcoming work. As the potential purchaser, Mr. Reinke’s fund had to react along with API to this request. Thus, the terms of the still-unfinished acquisition were rewritten so that this machine purchase could go ahead.
