▎ 摘　　要

NOVELTY - Particles comprise polymer resin compatible for three-dimensional printing process to print three-dimensional article (124) and 0.01-25 wt.% marking additive (122)that allows selective portions of the three-dimensional article (124) to change the color when exposed to a light. USE - Particles used for three-dimensional printer, particles with marking additive, marking of three-dimensional printed article (all claimed). Uses include but are not limited to powder bed fusion, selective laser sintering, selective heat sintering, binder jetting, and multi jet fusion. ADVANTAGE - The particles ensures improved light fastness and weatherability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) production of particles with marking additive (122)(122)for a three-dimensional printer, which involves providing a polymer resin compatible with the three-dimensional printer and mixing the polymer resin with 0.01-25.00 wt.% marking additive to form the particle with the marking additive; and (2) marking of three-dimensional printed article printed with particles containing marking additive, involves receiving by a processor tom provide instructions to print the three-dimensional printed object, controlling by the processor of powder-based three-dimensional printer to print the three-dimensional printed article in accordance with the instructions, receiving by the processor to mark the instructions based on marking for the three-dimensional printed article, and controlling by the processor using a laser to expose surface components of three-dimensional printed article based on marking instructions to change the color of the surface components of three-dimensional printed article to write the marking on the surface of the three-dimensional printed article. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of selective laser sintering-based printer. Selective laser sintering-based printer (100) Memory (104) Movable platform (112) Roller (116) Hopper (120) Marking additive (122) Three-dimensional printed article (124) Light source (126)
