摘要： The present disclosure is drawn to material sets for 3-dimensional printing, 3-dimensional printing systems, and 3-dimensional printed parts. A material set can include a powder bed material of composite particles including glass beads coated with polyamide-12 polymer. The composite particles can have an average particle size from 20 μm to 200 μm, and the polyamide-12 polymer can include greater than 80 meq/g carboxylic end groups and less than 40 meq/g amino end groups. The fusing agent can include an energy absorber capable of absorbing electromagnetic radiation to produce heat.

摘要： A detailing agent for three-dimensional (3D) printing includes a colorant present in an amount ranging from about 1.00 wt % to about 3.00 wt % based on a total weight of the detailing agent. The colorant is a dye having substantially no absorbance in a range of 650 nm to 2500 nm. The detailing agent also includes a co-solvent, a surfactant, and a balance of water.

摘要： The present disclosure is drawn to material sets for 3-dimensional printing, 3-dimensional printing systems, and 3-dimensional printed parts. A material set can include a polyamide polymer powder having an average particle size from 20 μm to 120 μm and a fusing agent. The polyamide-11 can have a solution viscosity from 1.5 to 1.75 at room temperature, and may increase by no more than 5% after exposure to 180° C. for 20 hours. The fusing agent can include an energy absorber capable of absorbing electromagnetic radiation to produce heat.
