Mirel bioplastic performs well as a film when annealed for two to three seconds after processing. New data on the PHB polymer was presented at the opening of the Annual Technical Conference (ANTEC) of the Society of Plastics Engineers in Boston today by Ray Krishnaswamy of Metabolix, the technology startup behind Mirel. Annealing relaxes stresses in noncrystalline chain segments, dramatically improving tear properties. Annealing equipment that could be used commercially includes IR heaters, embossing stations, or annealing roll stands. “We could build this for you for $1,000,” said to a large audience at the Fundamentals & Fellows Forum. Future research opportunities for bioplastics include controlling the rate of biodegradtion, controlling crystallization, improving thermal stability, exploring blends, and education.
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.
