Abstract
A material set can include a powder bed material, including a polymer powder and a fusing agent. The polymer powder can have a particle size distribution having the following profile: D10 of 30 μm or more, D50 from 50 μm to 65 μm, and D90 of 100?m or less. Other parameters can include a melting point from 100° C. to 300° C., a processing window temperature of 20° C. or more, an energy density absorption of 20% or less, and a melt flow index from 10 cc to 80 cc at 10 minutes. The fusing agent can include an energy absorber capable of absorbing electromagnetic radiation to produce heat.
