Abstract

The present invention concerns a system and method for fabricating a three-dimensional object. A build platform is provided that defines a build area and includes a print bed within the build area. Also provided is an extruder that extrudes build material. An ejector having at least one arm that has at least two opposing ends is used to remove the printed object. The first end of the ejector is adapted to travel in a vertical direction and the second end is adapted to travel in a horizontal direction. A scraper portion extends horizontally, parallel to the print bed from a retracted position to an extended position when the first end travels in a vertical direction towards the print bed.
