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 The parts were withdrawn at the last moment because of other engineering concerns.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.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
