Additive manufacturing, i.e. manufacturing of three-dimensional [3D] objects by additive deposition, additive agglomeration or additive layering, e.g. by 3D printing, stereolithography or selective laser sintering

Classification Context

Section:

PERFORMING OPERATIONS; TRANSPORTING

Class:

SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING

Scope Notes

Glossary: three-dimensional [3D] printing three-dimensional printing 3D printing additive manufacturing where the buildup of successive layers of material includes the use of a printer-like device having a motor-controlled head for dispensing materials that form the layers stereolithography additive manufacturing technique where the successive layers of material are formed by selectively hardening regions of polymeric material successively applied to the structure, typically by the use of laser light
