In this paper creating optical elements with the use of 3D printing technology was elaborated on. A special focus was put on the properties of nanodiamond and possibilities of applying it in 3D printing process in a mixture with the standard 3D printing resin. Several printouts have been completed, starting from the calibration printouts and ending with optical flats and both cylindrical and spherical lenses. The printouts have been tested for their abilities to transmit and absorb light in a wide spectrum of wavelengths. Full Text: PDF ReferencesL. Ding, R. Wei, and H.
