Abstract
An optimal printing speed and orientation for an object to be manufactured using an additive manufacturing process in which a photo-curable resin is cured through exposure to radiation are estimated by determining, for pixel maps defining cross-sections of the object, a critical size of a convolution kernel which provides an activation map having a maximum activation pixel value less than or equal to a predetermined threshold value. For each respective pixel map, a printing time is estimated as a function of an adjusted base lift velocity and base lift height of the printing apparatus. The optimal printing speed and orientation are then estimated as a minimum value of a function of the printing times for all respective pixel maps of the cross-sections of the object at each of a plurality of possible orientations of the object.
