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.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
