While research is ongoing to determine just how unhealthy 3D printing fumes are, there are also a lot of ways that the technology is actually environmentally friendly, from recycled filaments to reducing carbon emissions. This last is the focus of a proof-of-concept project developed by Autodesk research scientist Andreas Bastian at the company's Pier 9 technology center in San Francisco. In an effort to "bridge the gap" between 3D printing and metal casting, he's created a lightweight frame for an airplane seat, which could not only reduce carbon emissions, but also save airlines a lot of money.
