3D printing is a form of additive manufacturing that allows for quick and easy prototyping of components to speed up a design process. While there is still a lot of work that goes into making a part, it is much faster than sending the work elsewhere, and allows the creator to have a full-sized model in hand in a few hours.
Harmony Castings is a job shop for cast aluminum parts. Several secondary operations are required after the casting process: gate and sprue cutting, heavy flash grinding, and surface finish grinding. Each operation is performed by an operator using hand-held equipment. This leads to strain from repetitive tasks, and increased labor.
