1. A powder composite fabrication machine comprising:
a build platform defining a top side and a distribution chamber that is opposite to the top side and in communication with the top side via a plurality of holes;
a powder transfer device configured to deliver a first layer of a powder material to the top side of the build platform;
a resin supply system configured to deliver a photocurable material through the build platform and via the distribution chamber and the plurality of holes for infusion into the first layer of the powder material; and
an imaging device positioned above the top side of the build platform and configured to irradiate at least a portion of the photocurable material in the first layer of the powder material to form at least a portion of a first layer of a powder composite component from the first layer of the powder material infused with the photocurable material,
wherein the powder transfer device is configured to deliver a second layer of the powder material on the first layer of the powder material, the resin supply system is configured to deliver the photocurable material through the build platform and the first layer of the powder material infused with the photocurable material for infusion into the second layer of the powder material, and the imaging device is configured to irradiate at least a portion of the photocurable material in the second layer of the powder material to form at least a portion of a second layer of the powder composite component from the second layer of the powder material infused with the photocurable material.
