The present invention relates to a composite particulate build material comprising 92 wt% to 99.5 wt% polymeric particles having an average size of 10 [mu] m to 150 [mu] m and an average aspect ratio of less than 2: 1. The composite particulate build material additionally comprises from 0.5% to 8% by weight of reinforcing particles having an average size of from 0.1 탆 to 20 탆 and an average aspect ratio of from 3: 1 to 100: 1, applied to the surface of the polymeric particles . |
