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.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
