To improve manufacturing accuracy in stereo-lithography modeling, it is important to quantify the influence of laser power, laser beam diameter, scanning speed and the properties of photo-curing resin on the cured form of the resin, or cured resin thickness and width. Thirteen types of photo-curing resin prepared by changing the quantity of the initiator added to the resin were tested to examine the effect of resin properties, estimating the dimension of cured resin. It concluded as follows. (1) The phase change limit energy density and attenuation coefficient of the resin can be approximately expressed as a function of the quantity of initiator added. (2) The estimated values for thickness and width of cured resin, using approximated phase change limit energy density and attenuation coefficient of the resin, are well coincident with the measured values, implying thickness and width of cured resin can be estimated within practically allowable error. (3) Thus, once the quantity of the initiator added to the resin and the maximum energy density of the laser beam are given, the thickness and width of the cured resin are determinable.
