In 1999, Protomold (now a service of Proto Labs), Maple Plain, MN, changed the face of plastic injection molding with a computerized process that could turn a 3D CAD model into real injection molded parts in five days. The process was faster than traditional molding and, for quantities from a handful to several thousand, it cost less. This let designers quickly get prototypes with all the properties of production parts for early functional testing.

It's not easy for medical manufacturers to ensure their medical devices are reliable. For example, upon examination, seemingly identical lead wires in a random sample were found to have up to a 10X variation in durability. How much of this variation is caused by the manufacturing process and how much by differences in material or even residual stresses induced when the wire is spooled? Trial-and-error testing simply can't begin to solve such problems.
