B29C 64/00 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
Introduced: January 2017
Additional Content IPC
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
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
IPC defines codes here since 2017.
