An April Additive Manufacturing Odyssey: RAPID + TCT 2018

The Rapid + TCT 2018 conference and trade show, produced by SME, took place April 23-26 in Ft. Worth, TX, with a focus on closing the 3D printing knowledge gap and accelerating the adoption of additive manufacturing.

Before the April 24 keynote, Michael Grieves, the executive director of the Center for Advanced Manufacturing and Innovative Design and a professor at the Florida Institute of Technology, introduced one effort to close that gap: the ITEAM (Independent Technical Evaluation of Additive Manufacturing) Consortium.

“The ITEAM mission is the creation and operation of an analysis platform—a dynamic repository of equipment and material capabilities to evaluate the ‘can I make it, should I make it’ questions ... the technical and business issues that are going to drive additive manufacturing,” he said. “We want to engage feedback from actual user experience to close the gap between theoretical—what people think is going to happen—and actual performance.”

The SME platform is being developed and tested by the ITEAM consortium in collaboration with Grieves, GM and other major industry users in automotive and aerospace. It is developing a methodology called SAM-CT (size, accuracy and materials + economic evaluation of cost and throughput) to help would-be additive manufacturing users identify when and where the technology would be suitable.

On the people side of the knowledge gap, Stratasys and a consortium of colleges and universities announced a new industry certification program in North America just before RAPID that is intended to enable students to prove their additive manufacturing workforce readiness. Learn more about the certification program here.

Behind the stage curtain where Grieves presented his RAPID address, more than 300 exhibiting companies were ready to explain how their products and services would advance the additive manufacturing efforts of the 6,000+ attendees.

New Products from RAPID + TCT 2018

In addition to the certification program, Stratasys launched the new F900 Production 3D Printer, the third generation of the company’s flagship FDM system. Features include an MTConnect-ready interface with production-ready accuracy and repeatability, according to the company. It is available as a series of three solutions: the F900, the F900 AICS (Aircraft Interiors Certification Solution), and the F900 PRO. Stratasys also expanded the number of 3D printers compatible with carbon fiber composite material, demonstrated enhancements to its GrabCAD Print software, previewed Jigs and Fixtures for GrabCAD Print software and demonstrated its Stratasys J750 3D Printer alongside the new Stratasys J735 3D Printer.

Speaking of ceramics, XJet demonstrated its Carmel AM Production System at RAPID. The 3D printer uses NanoParticle Jetting (NPJ) technology to print separate nanoparticle “inks” or fluids for the build and support materials. This allows manufacturers to produce ceramic or metal parts with complex geometries. Days after the RAPID event, the first XJet Carmel 1400 installed in the U.S. was on display at its new home in the Youngstown Business Incubator in Ohio, just across the parking lot from America Makes during a May 1 open house.

“We believe XJet brings tremendous capabilities to the membership,” said Rob Gorham, executive director of America Makes via a press release. “By delivering near-net-shape of parts, post processing and final machining is reduced. It’s going to allow us to enhance some of the functionality that we can drive into the parts through advanced design technologies. Another challenge that the industry is facing is the lack of material choices. In terms of material options, the opportunities surrounding ceramics could be transformative in the industry.”
