Aerospace company Lockheed Martin filed a patent for making synthetic diamonds from 3D printing.

3D printing can create a diamond drill bit with “almost any geometry,” as well as other industrial objects such as brake pad inserts and lightweight armor, the U.S. patent filing said.

Inventor David Findley’s method involves depositing alternating layers of a ceramic powder and a pre-ceramic polymer dissolved in a solvent. Each layer of the pre-ceramic polymer is deposited in the shape that corresponds with the object being created. The deposited materials are then heated to at least 100 degrees celsius.
