I’ve been highly critical of “greenwashing” in this space where companies make environmental claims for their products that are often half-baked. I came across an effort today by Herman Miller, however, that is very impressive. Design engineers at the Michigan office furniture manufacturer have adopted cradle-to-cradle, a design protocol that advocates the elimination of waste by recycling a material or product into a new or similar product at the end of its intended life, rather than disposing of it. There are three fundamental components: 1) eliminate hazardous material chemistries, 2) design for disassembly, and 3) use recycled content to the extent possible. Some materials on the Herman Miller “hit” list are: formaldehyde-based particleboard, fiberglass, antimony oxides, PVC, some metal finishes, halogens and fluorochemicals. Wow. In some cases, Herman Miller is actively lobbying producers to make changes. The company has a great environmental glossary on its Web site.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
