Claim:
1. An assembler device for constructing a three-dimensional part in a layer-wise fashion from liquid resin wherein a layer has a cross-section and a thickness, the device comprising: an image plate comprising: a cure inhibiting layer located on an area of the top image plate surface to prevent curing of an adjacent volume of liquid resin; a build table located adjacent to the image plate, wherein the build table comprises: wherein the vertical distance between the image plate and the part being constructed may be altered by sliding the part between a first part position over the high elevation area and a second part position over the low elevation area; and a sweeper, the sweeper comprising: wherein the image plate is slidable between a first image plate position and a second image plate position; wherein the first sweeper portion extends to a top of the cure inhibiting layer to be in contact with the cure inhibiting layer, the sweeper is positioned across a side of the cure inhibiting layer such that the image plate slides in a single plane relative to the sweeper to retard the flow of liquid resin when the first sweeper portion contacts the cure inhibiting layer, to expose at least a portion of the cure inhibiting layer to the atmosphere, and remove debris from the cure inhibiting layer when the debris comes into contact with the sweeper as the image plate slides between the first image plate position and the second image plate position.
