Abstract
The present disclosure is drawn to a particulate build material for three-dimensional printing. The particulate build material can include a plurality of particulates, wherein individual particulates include a particulate core having a photosensitive coating applied to a surface of the particulate core. The particulate core includes a metal, a ceramic, or both a metal and a ceramic. The photosensitive coating includes a polymer having a photosensitive agent suspended or attached therein.
Claims17
A particulate build material, comprising a plurality of particulates, wherein individual particulates comprise a particulate core having a photosensitive coating applied to a surface of the particulate core, the particulate core comprises a metal, a ceramic, or both a metal and a ceramic, and wherein the photosensitive coating comprises a polymer having from 5 wt % to 15 wt % of a photosensitive agent suspended or attached therein.
A system for three-dimensional printing, comprising:
- a particulate build material for three-dimensional printing including a plurality of particulates, wherein individual particulates comprise a particulate core having a photosensitive coating applied to a surface of the particulate core, the particulate core comprises a metal, a ceramic, or both a metal and a ceramic, and wherein the photosensitive coating comprises a polymer having from 5 wt % to 15 wt % of a photosensitive agent suspended or attached therein, and a photo energy source to emit photo energy to the particulate build material, wherein the photosensitive agent absorbs energy corresponding to a frequency of the photo energy such that the photosensitive agent causes the polymer to soften and adhere to adjacent particulates.
