B33YADDITIVE MANUFACTURING, i.e. MANUFACTURING OF THREE-DIMENSIONAL [3-D] OBJECTS BY ADDITIVE DEPOSITION, ADDITIVE AGGLOMERATION OR ADDITIVE LAYERING, e.g. BY 3-D PRINTING, STEREOLITHOGRAPHY OR SELECTIVE LASER SINTERINGThis subclass covers additive manufacturing, irrespective of the process or material used.This subclass is intended to enable a comprehensive search of subject matter related to additive manufacturing by combination of classification symbols of this subclass with classification symbols from other subclasses. Therefore this subclass covers aspects of additive manufacturing (e.g. 3D printing) that might also be entirely or partially covered elsewhere in CPC.This subclass is for obligatory supplementary classification of subject matter already classified as such in other classification places, when the subject matter contains an aspect of additive manufacturing.The classification symbols of this subclass are not listed first when assigned to patent documents. B33Y10/00 B33Y10/00Processes of additive manufacturing B33Y30/00Apparatus for additive manufacturingDetails thereof or accessories therefor B33Y40/00Auxiliary operations or equipment, e.g. for material handlingGroup B33Y40/00 is impacted by reclassification into groups B33Y40/10 and B33Y40/20.
Groups B33Y40/00, B33Y40/10, and B33Y40/20 should be considered in order to perform a complete search. B33Y40/10Pre-treatmentGroup B33Y40/10 is incomplete pending reclassification of documents from group B33Y40/00.
Groups B33Y40/00 and B33Y40/10 should be considered in order to perform a complete search. B33Y40/20Post-treatment, e.g. curing, coating or polishingGroup B33Y40/20 is incomplete pending reclassification of documents from group B33Y40/00.
Groups B33Y40/00 and B33Y40/20 should be considered in order to perform a complete search. B33Y50/00Data acquisition or data processing for additive manufacturing B33Y50/02for controlling or regulating additive manufacturing processes B33Y70/00Materials specially adapted for additive manufacturingGroup B33Y70/00 is impacted by reclassification into group B33Y70/10.
Groups B33Y70/00 and B33Y70/10 should be considered in order to perform a complete search. B33Y70/10Composites of different types of material, e.g. mixtures of ceramics and polymers or mixtures of metals and biomaterialsGroup B33Y70/10 is incomplete pending reclassification of documents from group B33Y70/00.
Groups B33Y70/00 and B33Y70/10 should be considered in order to perform a complete search. B33Y80/00Products made by additive manufacturing B33Y99/00Subject matter not provided for in other groups of this subclass
