There was plenty of evidence throughout the halls of National Manufacturing Week held this week in Rosedale, IL that the medical market will become increasingly important to the U.S. economy. Teknor Apex, for example, unveiled 33 Medalist compounds all tested for compliance with ISO 10993-5 cytotoxicty standards and free of animal-derived materials, vinyl, phthalates and latex. Removal of animal-derived materials, such as stearates, derives from fears related to mad-cow disease, says Lisa M. Charno, market manager for the thermoplastic elastomer division at Teknor Apex. Another exhibitor, Elite Mold & Engineering purchased two all-electric injection molding machines to pave the way into the growing medical device market. “We believe this market will eventually account for 75 percent of our business,” says Joseph Mandeville, president of the Michigan molder. An interesting new technology for medical devices has been enhanced by another exhibitor, Saint-Gobain Performance Plastics. Two-shot molding is now becoming a factor in the medical device market because of new commercial grades of USP Class VI self-bonding silicones. They bond to rigid thermoplastics in the mold, avoiding costly secondary operations.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
