Use of bioabsorbable polymers as a medical device is moving to what I think is an amazing new level. Abbott vascular announced successful initial tests of a full bioabsorbable stent used to prop open diseased coronary arteries. The device is called ABSORB because it is completely absorbed back into the body after it restores blood flow, and the blood vessel heals. Six month results for the first 30 patients in the Abbott trial showed similar rates of success as metal stents. The new stent is made of polylactic acid, which is widely used in dissolvable sutures and anchor screws. Engineers in Japan are also rapidly developing mechanical applications for PLA.
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.
