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