Piston Driven Part Removal Mechanism with Non-Local Visual Feedback and Threaded Kinematic Contacts for Easy Print Plate Removal Used for Automated Network Capable 3D Printers

Three-dimensional printing system with automated part removal. In one embodiment, the system includes a printing surface on which a part is made and a printing device supported for controlled movement with respect to the printing surface to print the part on the printing surface. A blade is supported for motion across the printing surface to release the part from the printing surface. The present printing system according to the invention requires fewer user steps than known in the prior art.
