Patent number: 6652797Abstract: A method for determining the areas of resin to be cured in an optical stereolithography process for rapid prototyping using sequential laser curing of layers of a resin having a selected thickness to produce a desired shape of cured resin. The method includes the steps of generating a computer model of desired shape and dividing the model into layers of thickness equal to the thickness of the layers each defining an area of resin to be cured. A set of layers including and sequentially adjacent an intermediate layer is selected and the areas in the intermediate layer of resin which would be oversized by laser curing of layers later in the curing sequence is determined. The 2-D layer data used to build a 3-D model is modified to compensate for the oversizing and the steps repeated by sequentially selecting sets of layers to include substantially all of the layers as the intermediate layer.Type: GrantFiled: May 30, 2001Date of Patent: November 25, 2003Assignee: National University of SingaporeInventors: Ying Kit Chew, Yoke San Wong, Ying His Jerry Fuh, Han Tong Loh, Yeh Ching Andrew Nee, Yoo Sang Choo, Li Lu, Kah Bin Lim, Chee Leong Teo, En Tang Kang, Tetsuo Miyazawa
