1. A solid imaging apparatus for making a three-dimensional object from solid imaging material, the solid imaging apparatus comprising:

  • a cartridge including a supply of solid imaging material;

    a tray that holds solid imaging material dispensed from the cartridge;

    a coater bar for applying the dispensed solid imaging material on the tray;

    a moving portion connected to the coater bar to selectively move the coater bar along an x-axis within the solid imaging apparatus; and

    an imager that projects actinic radiation onto a layer of solid imaging material in the tray to selectively cure the layer of solid imaging material,wherein the coater bar comprises;

    a first scraping edge extending generally along a y-axis within the solid imaging apparatus;

    a second layering edge extending generally along the y-axis within the solid imaging apparatus; and

    a connection portion adapted to connect the coater bar with the moving portion, wherein the connection portion defines at least two connection positions for connecting the coater bar to the moving portion, and wherein a first connection position causes the first scraping edge to be the lowermost portion of the coater bar and the second connection position causes the second layering edge to be the lowermost portion of the coater bar.
