Abstract
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.
