3D printing is used to produce prototypes and\/or low production parts without the time or expense of tooling.\u00a0 This allows engineers and designers to quickly get their hands on actual parts to prove out and test a design for form and fit before committing to expensive tooling.\u00a0 3D printing, or additive manufacturing, is a process where successive layers of material are laid down in different shapes to produce a solid three dimensional object of virtually any shape from a digital model.<\/p>\n<\/div>
