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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
