Abstract
The present disclosure is drawn to a composite particulate build material, including 92 wt % to 99.5 wt % polymeric particles having an average size from 10 μm to 150 μm and an average aspect ratio of less than 2:1. The composite particulate build material further includes from 0.5 wt % to 8 wt % reinforcing particles having an average size of 0.1 μm to 20 μm and an average aspect ratio of 3:1 to 100:1 applied to a surface of the polymeric particles.
Claims15
A material set for 3D printing, comprising:
- a composite particulate build material, including:
- 92 wt % to 99.5 wt % polymeric particles having an average size from 10 μm to 150 μm and an average aspect ratio of less than 2:1, and
- 0.5 wt′% to 8 wt % reinforcing particles having an average size of 0.1 μm to 20 μm and an average aspect ratio of 3:1 to 100:1 applied to surfaces of the polymeric particles, wherein the reinforcing particles include mica or glass;
- and
- a fusible ink, including:
- a liquid vehicle;
- and
- electromagnetic radiation absorbing solids dispersed in the liquid vehicle which are suitable for receiving electromagnetic energy from an energy source and fusing with the composite particulate build material when contacted with the composite particulate build material and irradiated by the electromagnetic energy.
