DuPont this morning announced an expanded slate of renewably sourced polymers that will contribute to the company’s goal of doubling revenues from sustainable resources to at least $8 billion by 2015. Chief among the new offerings are Sorona EP thermoplastic resins, Hytrel RS thermoplastic elastomers, Biomax RS packaging resins and Selarâ VP breathable films. A key ingredient in Sorona EP is Bio-PDO, which is made at the recently inaugurated DuPont Tate & Lyle Bio Products facility in Loudon, TN. Bio-PDO replaces petrochemical based 1,3 propanediol (PDO) and/or 1,4-butanediol (BDO) in two glass-reinforced grades of Sorona EP that will initially be available. Sorona EP is compared to polybutylene terephthalate (PBT). Sampling is under way with broader availability expected in 2008. No disclosure was made on beta sites where the material is being tested.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
