While introducing a keynote speaker at RAPID 2014, SME President Michael F. Molnar joked that, after 21 years, the rapid prototyping and manufacturing event was finally old enough to buy a drink. It was an appropriate analogy as one of the event’s biggest segments, 3D printing, has matured to the point of being accepted by many of the companies that attended The Big M, a manufacturing conference co-located with RAPID 2014 for the first time this year in Detroit.
In fact, the RAPID side of the exhibition hall was noticeably more crowded than The Big M side, as attendees crowded booths filled with 3D printers, 3D scanners, metrology equipment, computer-aided manufacturing machines, as well as materials and software.
“The caliber of company names on the badges of people visiting our booth has been really impressive this year,” said David Burns, president and chief operating officer of ExOne. He said big industry is now showing a keen interest in additive manufacturing.
The Big M co-location and the Detroit venue may have contributed to the spirit of the event. Many of the presentations and announcements at RAPID 2014 focused on the role advanced manufacturing have to play in boosting the profile of manufacturing in America.

The program will offer starter kits intended to transform shop classes and incorporate additive manufacturing into curriculums.
“We need the public and private sectors to work together now more than ever to focus our investments on areas with the highest potential for growth,” said Secretary Pritzker. “Our objective (at the Whitehouse Office of Manufacturing Policy) is to break down the silos across the government and encourage meaningful public-private partnerships at every level to move American manufacturing forward.”
Terry Wohlers’ data seemed to support the hypothesis that industry has latched onto 3D printing. Wohlers is principal consultant and president of Wohlers Associates, which produces an annual report on the state of the additive manufacturing industry.
He opened the final day of the conference by pointing out trends he has seen over the past year. According to the 2014 Wohlers Report, sales of 3D printers capable of producing metal parts increased almost 76% vs. 2012. Such machines are not widely used by hobbyists. That growth is primarily coming from the medical, dental and aerospace industries.

A tour of ExOne's nearby facility in Troy, MI, revealed the company is beta testing a ceramic material for use in its additive manufacturing machines that dispense layers of resins into specially engineered sands or powders. Representatives of the company explained how they take customer design files, prepare them for 3D printing, perform quality checks on the physical products and ship them out.
