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.

Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
