When is which production method worthwhile: 3D printing or injection molding?

Injection molding is a time-tested process for the production of identical plastic parts in large batch sizes. In this process, a negative mold of the component to be produced is first milled from solid material, usually aluminum or steel, and then installed on an injection molding machine.

The heated and liquefied material is injected into the mold, cools there and can be removed as a finished component. 3D printing, on the other hand, uses an additive manufacturing process in which the component is built up layer by layer in the build space of the 3D printer. Once printing is complete, the component can simply be removed from the printer. Depending on the technology, support structures may still need to be removed afterwards.
