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 Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
