Consider specialty compounds to take advantage of growing interest in molded liquid silicone rubber. Advantages of silicone rubbers include flexibility, thermal stability over a broad temperature range, resistance to solvents, and excellent biocompatibility. Silicones are increasingly being selected by design engineers for valve seats or hoses in autos and aircraft, where their resistance to solvents can be boosted through incorporation of fluorosilicones. Polyurethane is added to improve tear strength for some medical applications. New developments in specialty compounding were reviewed by Mary Krenceski, a research scientist at Extreme Molding in Watervliet, NY at Molding 2008.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
