"Today's MEMs designers face a difficult design hurdle: Combining fabrication process information with 2D-mask geometry for creating 3D structures," says Victor Yarberry, principal member of Sandia National Lab's technical staff. "The fundamental problem is that a 2D mask does not reveal the true 3D structure." For addressing this problem, the Lab's scientists created SUMMiT (Sandia Ultra-Planar Multilevel MEMS technology) software. Sandia is making the software's source code available. The software's 3D model generator applies fabrication steps to 2D masks for creating a solid model. "Currently, there are no commercial tools that can model the entire SUMMiT process, which includes a wet undercut etch followed by a conformal deposition," says Yarberry. The new code uses algorithms for providing representations of conformal depositions on the underside surface. "These steps allow creation of important mechanical features, such as gear hubs and hinge points by the designer," he says. He notes that MEMs devices are being designed into computer disk drives, optical communication switching devices, and accelerometers for automotive air bags.

Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
