Abstract
The present disclosure describes an apparatus (10) for additively manufacturing a three-dimensional object. The apparatus (10) includes a radiation source (13), a carrier (1) on which the three-dimensional object is made, an applicator assembly (3) configured to apply a polymerizable liquid, and a frame (8), with the applicator assembly and the radiation source connected to the frame. A first drive assembly (4) interconnects the applicator assembly and the frame and a second drive assembly (2) interconnects the carrier and the frame. The frame defines a build region (6) between the applicator assembly and the carrier. The applicator assembly includes a polymerizable liquid supply chamber, an application roller (11), and a metering roller (12). The applicator assembly may optionally include a post-metering roller (14). An apparatus comprising a first and a second applicator assembly and a smaller scale version of the apparatus are also described.
