Additive Manufacturing as bridge production and other uses

In a presentation at Virtual Engineering Days, Joe Cretella, applications engineering manager at ProtoLabs, offered technical examples about how multijet fusion (MJF) can best be used, while Brent Ewald, solutions architect from HP, talked about developing strategies for using MJF and encouraged companies to think about how the technology can complement their more traditional manufacturing efforts.

Cretella began by noting that the ideal applications for multijet fusion can include prototypes and end-use parts; complex geometries requiring hinging or light weighting, high strength, and temperature resistance; jigs and fixtures, brackets, clips; and component housings.

He cited a recent case study that ProtoLabs did with a university in France and its German counterparts to produce reusable face shield. Cretella said they were able to optimize the design so that it could be printed as a single component. “So it could fit a large number of those face shields into a single build,” he explained. “And that’s really going to be key on thinking about designs, especially as we’re getting into talking about the parts, we want to be able to fit a high volume.”
