Acetal isn't just for injection molding anymore. At the recent National Plastics Exposition in Chicago, DuPont Engineering Polymers (http://plastics.dupont.com) introduced Delrin® acetal sheet suitable for thermoforming. Sold under the Delrin Forming Solutions name, these new products combine acetal's superior chemical resistance and lubricity with thermoforming's manufacturing edge when production volumes don't justify injection molding. Initial applications include housings and trays for use in medical, dental, and biochemical research settings.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
