Claim of US Patent No. 10,336,000

1. A method of operating a Continuous Liquid Interface Printing (CLIP) printer, the method comprising:receiving a set of objectives for fabrication of a three-dimensional (3D) object using the CLIP printer;
defining the 3D object as a plurality of different portions;
for each orientation of a plurality of orientations of the 3D object, performing a plurality of simulations of a fabrication of each portion of the plurality of portions of the 3D object using a different set of parameters for each simulation;
selecting a fabrication orientation from among the plurality of orientations for fabrication of the 3D object responsive to a determination that at least one simulation of the plurality of simulations achieves the set of objectives,
wherein a first set of parameters selected for a first portion of the object is different than a second set of parameters selected for a second portion of the 3D object;
and
fabricating the 3D object by the CLIP printer at the fabrication orientation using the first set of parameters for the first portion of the 3D object and the second set of parameters for the second portion of the 3D object,
wherein the set of objectives for fabrication comprises at least one mechanical characteristic of the 3D object, a surface finish of the 3D object, an indicator of accuracy of the fabricated 3D object relative to data used to fabricate the 3D object, a degree to which augmentation/modification of the 3D object is affected as a result of fabrication, and/or a speed at which the 3D object is to be fabricated, and
wherein the set of objectives for fabrication further comprises an indication of weighting of respective ones of the set of objectives.
