Abstract: Methods of printing parts, e.g., using a 3D printer, are disclosed. The methods include receiving a representation of a part to be printed. The methods include analyzing the representation along one or more of an X-Y plane, X-Z plane, and Y-Z plane to identify an aspect ratio of the part. The methods include comparing the aspect ratio to a threshold value. The methods further include determining that a support structure for the part is needed based on the comparison of the aspect ratio to the threshold value. The methods additionally include providing instructions to a 3D printer to print the part including the support structure.

Abstract: A 3D printing apparatus and method that compensates for offset in the deposition of print material as a result of nozzle movement. The compensation may include discretizing a path of travel of a 3D print nozzle into segments, compensating each path segment based on an expected offset of print material deposition, and generating a compensated path of travel. The compensation may apply an inversion of a system model that is based on an expected offset of print material deposition relative to the nozzle path of travel.
