Although three dimensional photofabrication is one of the new technologies that can make three dimensional parts using a simple process, improving, parts accuracy is one of the demands for industrial use. The knowledge of the mechanism of a solidified resin's unit shape will lead to the improvement of parts accuracy. This paper shows the measured and the analytical results of the solidified unit shapes where the laser-focal position is changed to the uncured resin surface. The results showed that solidified shape had a constricted profile at the mid point of slopes rather than a parabola profile where uncured resin surface was offset from the focal position. The analysis of the results clarified that these unit shapes should he estimated from the energy distribution irradiated on the uncured resin surface rather than the Gaussian energy distribution based on conventional assumption.
