Abstract
AbstractThe most important procedure for improving accuracy of modeling in stereo-lithography is toclearly identify the relationship between the conditions of laser irradiation and the solidification of photo-curing resin for modeling. The parametric study concerning laser power, laser beam diameter,laser scan speed and properties of photo-curing resin was conducted in order to find those influenceon the dimensional accuracy ofthe solidified resin. The findings are summarized below: (1) The thickness of solidified resin can be estimated by energy density at the center of laser, attenuation coefficient and critical curing energy density of photo-curing resin.(2) The width of the solidified resin is influenced by the state of laser beam diameter during irradiation.When the diameter on the photo-curing resin is varied, it is related to energy density at the center oflaser and the laser beam diameter, while it is a function of energy density alone when the diameteris kept constant.
