Suppliers of additive fabrication systems have been touting the potential for direct digital manufacturing for years. Now more of them are starting to walk that walk–by using their own additive machines to make parts for their new machines. The latest example comes from Stratasys, which this week revealed that 32 of the parts on its latest large-format fused deposition modeling (FDM) system were produced via FDM. This machine, the FDM 900mc, features a big 3×2x3-ft build envelope and has been designed from the ground up to support direct digital manufacturing. Among the FDM parts on the new machine is a touch-screen bezel. With direct digital manufacturing, Stratasys can create this low-volume part on demand, saving an estimated $100,000 of tooling costs and at least six weeks of tooling lead time. Stratasys isn’t alone in using its own technology to procure parts for its machines. EOS GmbH has employed a similar strategy on its Formiga P100 system. Read about it in this earlier post.

Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Weaned on the relatively effortless connectivity of today’s massive variety of consumer electronic products, automation users in the IIoT will likely not tolerate too many competing, piecemeal standards for long. And the Industrial Internet Consortium is trying to preempt history.
