The ejection mechanism design allows for removal of printed parts from a printer's build volume without taking up a lot of space when not in use. This design offers a major advantge for Delta style 3D printers because of their unique large vertical height and often non-rectangular footprint. The design allows closer placement of multiple machines and ensures reliable part removal for continuous, automatic printing of multiple parts.
Additionally, a part retrieval system has been developed to allow users to retrieve an ejected part without the possibility of interacting directly with the machine. This system is able to be reversed, through the use of a key, to gain access to the machine for maintenance. By using the same access point, cost and complexity are reduced in the end product.
