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.

The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
