Magnetically separate these, use parabolic mirrors to melt. Remove the dross. Cast & machine or 3D print. Strength should not be a problem.

Haven’t tracked back to the original paper. Do we know what the “light reacting binding agent” is?

Pivoting– there has recently been great progress in “cold sintering” techniques, where the material is processed anywhere from room-temp to 200 C., avoids hi-temp requirements and long bake times, but is just as structurally strong. Utilizes water and pressure. Works with a broad range of inorganics and ‘composites,’ which the Moon has a bit of, lying around.
