Thanks for that input, bobjengr. I've done several posts from that show, as have the rest of us who went. Here are my others: igus plastic bearings http://www.designnews.com/author.asp?section_id=1392&doc_id=271925 3D printing http://www.designnews.com/author.asp?section_id=1392&doc_id=271813 Baxter Robot http://www.designnews.com/author.asp?section_id=1392&doc_id=271846 SABIC's carbon composites for medical devices http://www.designnews.com/author.asp?section_id=1392&doc_id=271732 Disease-fighting materials http://www.designnews.com/author.asp?section_id=1392&doc_id=271712
Ann--I have used Penn fasteners and can "testify" they really do a great job depending upon the application. The micro-devices are ideal for the applications you mention in your post. I was very surprised at the shear and tensile some designs can tolerate. I'm really sorry I missed the show. Certainly seems like a great experience and I look forward to other posts you make relative to your visit.
The microPEM pins are so tiny you can barely see them with the naked eye, at least with my eyes unaided by glasses. The sample Penn gives out is so small and lightweight--2 super thin 1.5in diameter disks fastened together--it kept flying out of the pocket in my notebook (not a computer, an actual paper device I use to take notes on). I was also impressed by the many uses of silicone for adhesives, coatings, and other apps: it's a truly versatile material.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
