ABSTRACT:
Methods and apparatus are disclosed for the production of high precision large scale, micro and mini structures using three dimensional stereolithography. The objects formed using these methods have minimal stress between layers and low curl distortion. The objects also have low warpage because no post-cure treatment is necessary. The methods include the use of elevated pressure, elevated temperature, or sequential polymerization of polymer precursor fluid, or a combination of these, in the three dimensional stereolithographic process.
