Use of bioabsorbable polymers as a medical device is moving to what I think is an amazing new level. Abbott vascular announced successful initial tests of a full bioabsorbable stent used to prop open diseased coronary arteries. The device is called ABSORB because it is completely absorbed back into the body after it restores blood flow, and the blood vessel heals. Six month results for the first 30 patients in the Abbott trial showed similar rates of success as metal stents. The new stent is made of polylactic acid, which is widely used in dissolvable sutures and anchor screws. Engineers in Japan are also rapidly developing mechanical applications for PLA.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
Proto Labs is now offering an optical liquid silicone rubber (LSR) quick-turn molding service using Dow Corning's LSR material. Optical LSR is a transparent, flexible thermoset material that's replacing glass in many optical applications, especially lighting.
