Stratasys, the leading supplier of rapid prototyping equipment by volume, is now teaming up Ultem 9085 polether imide with new machines designed for direct digital manufacturing, which is the production of parts directly from CAD files. EOS is now offering PEEK (polyetheretherketone) polymer from Victrex for its laser sintering systems. Other manufacturers, such as Z Corp. and 3D Systems, are developing stronger proprietary materials. Ultem extends the digital manufacturing process into the aircraft market in a major way. Until now, Ultem 9085 was only available for use in conventional processing methods, such as injection molding, which require expensive tooling. Manufacturing using equipment originally developed for rapid prototyping creates opportunities for design engineers to make parts even more complex than is possible with injection molds. The cost of the materials coupled with processing time, however, will limit adoption, at least for now to low-volume parts

"carbon-fiber-ev A new nanoscale material developed by researchers at Imperial College London could eventually act as both the battery and body of electric cars. The mix of carbon fiber and polymer resin can charge and release electricity like a battery and is hard as steel too."
