Do the static-dissipative properties of ABS plastic relate specifically to the ABS (Acrylonitrile butadiene styrene)? That is, are there other materials which could also be used or is that why one uses ABS?
ESD properties can be applied to a number of diffeent plastics through special formulations. In this case, the treatment was applied to ABS because it's a widely used, low cost engineering plastic and conforms to the Fused Deposition Modeling technology developed by Stratasys.
There seems to be a lot of activity in the 3D printing sector lately, especially around the design and application of new materials. Any sense of why now or what's behind this accelerated pace of innovation?
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
