Rapidly, A Few More


Some other papers worth noting from the additive manufac- turing library include: rapid manufacturing with electron beam melting (“…A Manufacturing Revolution?” TP03PUB397); rapid manufacture of EDM electrodes using selective laser sintering (TP00PUB135); RP of high density circuitry (TP04PUB221), wind tunnel models (TP04PUB87), and nonuniform shapes (TP03PUB59); and advancements in rapid solidifi cation process tooling (TP04PUB338). Also, the past, present and future of rapid manufacturing in medicine (TP11PUB16); RP composite tooling (TP11PUB5); RP tooling considerations for RTM (TP- 97PUB16); rapid tool fabrication by powder metal forging (TP- 97PUB95); and RP using machining (TP99PUB53). A fi nal thought comes from TP91PUB444, “Rapid Product Development—A Competitive Advantage for the


’90s.” While mentioning prototyping (photopolymerization, selective laser sintering, fused deposition modeling and laminated object manufacturing) along with key technologies of CAD/CAM/CAE, advanced manufacturing processes and sourcing and partnering, rapid isn’t the paper’s focus. Yet the conclusions aptly describe the impact 3D/rapid/additive is having on advanced manufacturing.


The authors, from General Electric and speaking at SME’s


AUTOFACT ’91, predicted “the rapid innovators who adopt new technological and organizational approaches to product development will be the leaders in profi tability, growth, and technological innovation. It will be these innovators who will secure the competitive advantage.” ME TechFront is edited by Senior Editors Patrick Waurzyniak, pwaurzyniak@sme.org and Ellen Kehoe, ekehoe@sme.org.
