Pelican Products Inc. turned to low pressure structural foam molding to produce this collection of cube-shaped cases in sizes ranging from 18 to 24 inches. These big, watertight, dust-proof, chemical-resistant cases feature detachable steel casters and beefy molded-in handles. Pelican molds the cases from what it calls “an ultra-high-impact-resistant polypropylene.” To make the manufacturing as economical as possible, the company uses a dedicated lean production cell that molds the top and bottom of the case in the same steel tool.

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.
