You might initially think of flexible polymer parts when you think of the 3D printing process. However, the kind of objects you typically produce with a 3D printer (think prototypes, one-offs, short run productions, or shapes that don’t lend themselves to traditional manufacturing) may be better suited to stronger, more heat-resistant materials—metals.
