We all want to trust “the system” when it comes to issues such as potentially toxic chemicals that could affect our health. But new reports about polycarbonate baby bottles are disturbing. Research from the federal National Toxicology Program is said to raise ‘’some concern” about bisphenol A potentially leaching from polycarbonate baby bottles and other products. Rats exposed to the chemical showed disturbing changes, including some linked to cancer. Canadian health officials say bisphenol A may endanger humans and any may ban the substance from baby bottles. Polycarbonate producers such as Sabic Innovative Plastics are referring questions to Dr. Steven Hentges, a polycarbonate expert at the American Chemistry Council. The ACC has released a very guarded statement, which says that the new studies confirm their position that exposure to BPA is negligible. Dr. Hentges calls on the U.S. government to conduct more studies to affirm the safety of BPA. I wonder what Dr. Hentges is telling his family members about use of polycarbonate baby bottles, which are typically exposed to high heat in a dishwasher? I’ll bet he’s telling them to take no chances. Use safer BPA-free alternatives. Why take any chances? There are limits (big limits) to how far we should go to protect our chemical industry.
It’s not clear to what extent there are also health concerns about epoxy resins, which are typically made with bisphenol A and widely used as a coating in food n beverage cans.
The FDA has just released draft guidelines for using 3D printing in the design, development, and manufacture of regulated medical products. Although the recommendations are non-binding, they do set some much-needed parameters.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
