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.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
