Accurate build-time prediction for making stereolithography parts benefits the service industry with the information necessary for correct pricing and effective job scheduling. Derived from a detailed study of the laser scan mechanism of the stereolithography machine, the function between scan time and volume, area, scan velocity and various build parameters is concluded and verified. Instead of the conventional methods of predicting build-time based on the detailed scan and recoat information from the actual build file after slicing and adding supports, the present algorithm incorporates the geometrical features drawn from the STL file such as volume, surface, etc. and the statistical factor of support structures. By comparing the actual build-time observed from many jobs, this algorithm is proved to be effective, practicable and quite accurate.
