Abstract
In a coating method example, a coating is formed on a part precursor by blasting the part precursor with a blast medium. The blast medium includes blasting beads and a coating agent. The part precursor is formed from a polymeric build material, and a hardness of the blasting beads is greater than a hardness of the polymeric build material.
Claims9
A coating method, comprising:
- forming a coating on a part precursor by blasting the part precursor with a blast medium, the blast medium including:
- blasting beads;
- and
- a coating agent present in an amount ranging from greater than 0 wt % to about 0.4 wt % based on a total weight of the blast medium;
- wherein the part precursor is formed from a polymeric build material, and a hardness of the blasting beads is greater than a hardness of the polymeric build material;
- wherein:
- the coating agent is graphite;
- the coating agent is present in the blast medium in amount of about 0.1 wt % based on a total wt % of the blast medium;
- and
- the blasting beads are garnet.
