Abstract

To make the stereolithography process more useful in the manufacturing industry, the dimensional accuracy of the parts it creates should be very high. But due to the nature of the polymerization process and the mechanism of laser scanning, distortions are induced in the parts. Curl distortion is a major source of inaccuracy in this photopolymer based technology. This paper approaches the problem from a process related point of view by addressing the major parameters reponsible for curl.The work presented here is a continuation of a similar work presented at the SFF symposium in 1993 [1].
