Systems and methods for improved stereolithographic (SLA) three-dimensional printing are provided. The systems and methods utilize an array-lens to produce kaleidoscopic imaging patterns, which in turn are used to direct the curing of resin to produce a three-dimensional object. The array-lens can be used to replicate, superposition, and/or overlap or otherwise reconstruct an image received by the array-lens, onto a resin that is used to form the desired object. The systems and methods can further use an optical diffuser, with a distance between the optical diffuser and the array-lens being adjustable to provide a desired kaleidoscopic imaging pattern on the resin. Additional features and methods for use with the provided SLA three-dimensional printing systems and methods are also provided.
