Abstract: A method is provided for maintaining resin in a system including a main feed tank and at least one vat, each of the at least one vats associated with a 3-D printing machine. The method includes the steps of: transferring resin from the main feed tank to the at least one vat; operating the associated 3-D printing machine in a build cycle; returning the resin from the at least one vat to the main feed tank; and repeating in a cycle the steps of transferring the resin, operating the 3-D printing machine, and returning the resin.

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.

Abstract: The present disclosure generally relates to additive manufacturing of an object using both a digital light processing (DLP) projector and a focused energy source to irradiate a photopolymerizable material, and apparatuses and methods for the same. The DLP projector irradiates and cures an outer perimeter of the object, and the focused energy source irradiates and cures an inner region of the object. In a preferred embodiment, irradiation by both the DLP projector and the focused energy source occur from underneath a tank holding the photopolymerizable material and through a transparent window.
