TJ, the carbon composites are medical-grade materials, not food- grade materials, designed for less than 29 days of contact with the body. The other, non-carbon composite materials--ULTEM resin--used in the sterilization tray are for surgical instruments. That's not a food-grade material either.
Elizabeth, I had a similar "what?!" response on seeing the press release about the carbon composites and brought that question to the interview. It does make sense from both the materials perspective and the application POV.
Interesting story on the new materials being used in medical devices and the reasoning behind it. It's not a material I would've thought would have this application, either, Ann, but your article presents very clearly why it is working so well.
Maybe I shouldn't have been surprised at this development, but somehow I never thought of carbon composites as useful in medical applications. The truth is, there are lots of machines and equipment of various types that can benefit from this material.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
