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.
