Abstract:
The present disclosure generally relates to methods and apparatuses for additive manufacturing (AM) that utilize a pulsed laser to solidify a liquid photopolymer. The method includes scanning a first portion of the photopolymer with the laser at a first draw speed, wherein the first portion of the photopolymer corresponds to a first portion of the part that has a width less than a threshold width. The method also includes scanning a second portion of the photopolymer with the laser at a second draw speed that is greater than the first draw speed, wherein the second portion of the photopolymer corresponds to a second portion of the part that has a width greater than the threshold width.
