Abstract
An additive manufacturing machine includes: a resin support which has at least a portion which is transparent, wherein the resin support defines a build surface; a material depositor operable to deposit a resin which is radiant-energy-curable onto the build surface; at least two build stations, each build station including: a stage positioned adjacent the build zone and configured to hold a stacked arrangement of one or more cured layers of the resin; one or more actuators operable to manipulate a relative position of the stage and the build surface; and at least one radiant energy apparatus positioned opposite to the stage, and operable to generate and project radiant energy in a predetermined pattern.
