More than 70 percent of an ABS substitute is made from starch, palm oil, and carbon dioxide. The research team used it to manufacture a vacuum cleaner cover to demonstrate its usefulness in consumer products. (Source: Siemens)
I don't think we should have to trade off one sustainability factor against another, in this case, a styrene alternative vs using palm oil. Actually this is a three-way tradeoff, since it's a creative way to reduce and make use of CO2.
Thanks for your comments. I'm aware of the palm oil problem, which is not insignificant. I decided to report this anyway, because finding a substitute for styrene is a big deal, since it's also bad for the environment. Humans aren't the only beings that are affected by it. Since this material is still in R&D it's possible that BASF, which has a deservedly good rep in sustainability consciousness, might be looking for an alternative to palm oil.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
