Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . Three-dimensional printing system comprising: a printing surface on which a part is printed the printing surface including holes in an array; a printing device supported for controlled movement with respect to the printing surface to print the part on the printing surface; pins arranged in an array matching the array of holes; and means for pushing the pins through the holes to lift the part from the surface. 2 . The printing system of claim 1 wherein the means for pushing thee pins through the holes comprises lowering the printing surface onto the pins. 3 . The printing system of claim 1 wherein the means for pushing the pins through the holes comprises raising the pins. 4 . Three-dimensional printing system comprising: a printing surface on which the part is made, the printing surface including at least one hole beneath the part location; a printing device supported for controlled movement with respect to the printing surface to print the part on the printing surface; and compressed air means for introducing air through the hole to lift the part from the surface. 5 . Three-dimensional printing system comprising: a printing surface on which a part is made; a printing device supported for controlled movement with respect to the printing surface to print the part on the printing surface; and means for vibrating the priming surface to release the part. 6 . The printing system of claim 5 wherein an electromagnet vibrates the printing surface. 7 . Three-dimensional printing system comprising; a printing surface on which a part is made; and a support structure for supporting the printing surface, wherein the printing surface and support structure are kinematically coupled to provide rapid and precise leveling of the printing surface. 8 . The system of claim 7 wherein an underside of the printing surface includes grooves that mate with protrusions on the support structure to provide the kinematic coupling.
