The proposal seeks to demonstrate printing of material directly onto a precisely figured mandrel in order to eliminate secondary forming and polishing steps after the printing process. The first process is to electroform a very thin (i.e., 50 micron) layer of Ni onto a mandrel. Afterward the ceramic is printed onto the electroformed nickel, heat treated at low temperature, and then released. The second approach is to use a thin film release layer such as Titanium Nitride (TiN) which is deposited on the mandrel prior to printing of the ceramic. After printing the ceramic is heat treated at low temperature and then released.

This approach offers the potential to achieve a larger collecting area for a given mass budget in comparison to traditional electroformed optics.
