USE OF MULTIPLE BEAM SPOT SIZES FOR OBTAINING IMPROVED PERFORMANCE IN OPTICAL ADDITIVE MANUFACTURING TECHNIQUES

摘要

Methods and apparatuses for using multiple beam spot widths in order to obtain improved performance in optical additive manufacturing techniques are disclosed. In some embodiments, an optical additive manufacturing apparatus for manufacturing an object, comprises a scanner configured to direct a beam emitted by an emitter towards an object layer and a control module in data communication with the scanner. The control module may be configured to: calculate a plurality of hatch vectors; select two or more of the plurality hatch vectors to be compared; compare the two or more selected hatch vectors to a first combination parameter; and calculate a first new hatch vector based on the two or more selected hatch vectors.
