One of Hewlett Packard’s environmental goals is use of biobased plastics. It’s a goal that goes back at least six years, and so far it’s had a rocky path. Efforts to build a printer housing from plant-based went afoul a few years ago. “The first problem we had was the polylacticacid (PLA) we used came from genetically modified crops, and that never could have been used in Europe,” comments John Frey, who chairs Hewlett Packard’s environmental strategies council. “The other problem is that they weren’t really heat stable. I took one of the pilots to a meeting in downtown Houston and then left it in my car. When I came back, the whole shell had caved in around the printer mechanism.” More recently, HP came very close to shipping a notebook with two biobased parts. The parts were withdrawn at the last moment because of other engineering concerns. Frey says HP has its eye on kenaf to see if it can add required stability as a reinforcing material.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
