Publication number: 20190039304Abstract: A build plate system for a heated deposition three-dimensional printer includes a plurality of sheets, the plurality of sheets arranged in a stack on a build plate and a glue portion between each of the plurality of sheets. The glue portion is configured to hold a sheet to the stack and release the sheet from the stack when receiving heat from a nozzle of the three-dimensional printer. A method for operating a build plate system includes the steps of printing an object onto a top-most sheet of a plurality of sheets arranged in a stack, positioning the nozzle of the three-dimensional printer in thermal contact with the glue portion, applying heat to the glue portion by nozzle to release the top-most sheet from the stack, and moving the top-most sheet off of the stack into a target area using different methods of placing the nozzle into contact with the top-most sheet from the stack.Type: ApplicationFiled: August 4, 2017Publication date: February 7, 2019Inventors: John Matthew Nicklas, Anna Michelle Nicklas

Publication number: 20190039306Abstract: A system for printing three dimensional objects using a liquid-matrix support includes a motor, a resin, a stage, oil, and a light projecting source. The motor is an operating interface that is adapted to move the stage in an upward or in a downward direction. The resin in the system comprises a light polymerizable liquid. The light from the light projecting source is projected onto the resin to provide a shape to the three dimensional objects. The stage is adapted to move in the upward or in the downward direction to support the growing layers of the printed three dimensional objects. The oil is a non-aqueous hydrophobic and oleo-phobic component that is coupled at an interface with the resin by a liquid-matrix support which includes an additive. The light projecting irradiates the resin, and, in a preferred embodiment, irradiation passes through the oil to the resin.Type: ApplicationFiled: October 10, 2018Publication date: February 7, 2019Inventors: Omar BALTAJI, Moustafa Mohamed Hassan EID
