Title: Additive manufacturing of crystalline materials

Abstract

The present invention relates to additive manufacturing methods, in which crystalline materials can be formed by using a liquid precursor. In particular embodiments, the crystalline material is a perovskite. The methods include the use of a thermal voxel, which can be translated to form any arbitrary pattern of initial crystalline seed structure(s). Then, the seed structure can be incubated to promote crystal growth and/or crystal dissolution, thereby providing a patterned crystalline material.
