APPLICATION OF MULTIPLE BUNDLE SPOT DIMENSIONS FOR OBTAINING IMPROVED PERFORMANCE OF OPTICAL ADDITIVE PRODUCTION TECHNIQUES

摘要

Methods and apparatus for using multiple beam spot widths to achieve improved performance in optical additive manufacturing techniques have been disclosed. In some embodiments, an optical additive manufacturing device for producing an object includes a scanner configured to direct a beam emitted from an emitter toward an object layer and a control module in data communication with the scanner. The control module can be configured to: calculate a variety of hatch vectors; selecting two or more of the plurality of hatch vectors to be compared; comparing the two or more selected hatch vectors with a first combination parameter; and calculating a first new hatch vector based on the two or more selected hatch vectors.
