• The Plastic Materials Development course is designed to give a solid foundation on understanding polymer families, material properties, and shrink and warp characteristics.

    The course begins with discussions on making polymers out of monomers, followed by the importance of molecular weight to the part performance and processing. The course then dives into other topics such as drying, additives, viscosity and rheology. The discussion then leads into what makes some polymers amorphous and others semi-crystalline and how that classification impacts material properties, processing, mold design and part design. Finally the course dives deeper into understanding and recognizing volumetric versus orientation-induced shrinkage, and how each causes plastic parts to warp. Students will learn critical thought processes that help them distinguish between the various root causes of warp, followed by practical strategies for reducing warp by evaluating options in material selection, mold design, processing and part design.
