Zusammenfassung:	The present disclosure relates to devices and methods for the production of optical devices and other objects requiring precise surfaces and/or complex geometries. Mold sections with optically precise surfaces and/or surface features having labyrinthine geometries prepared using additive manufacturing processes are provided. Methods of preparing mold sections by applying mold inserts by additive manufacturing processes are also provided. A mold insert with an optically precise surface and/or surface features with a labyrinthine geometry may be manufactured using an additive manufacturing process without any need for further tooling.
