Advances in Stereolithography Accuracy

It has been almost four years since the SLA - 1 ushered in the new technology of StereoLithography, and about 2\ years since 3D Systems introduced the SLA-250. Since then, nearly 300 systems have been installed worldwide and are currently providing benefits in a range of applications which might well be summarized by the term "Rapid Prototyping and Manufacturing" or "RPM". During the past year the accuracy of parts built with stereoLithography has benefitted significantly from nine important technological advances. The research and development efforts which formed the foundation for this progress originated within the Process, Chemistry and Software departments of 3D Systems. The following is a listing, and brief description, of the key features of each of these advances.
