Title: SYSTEM FOR PRINTING THREE DIMENSIONAL OBJECTS USING A LIQUID-MATRIX SUPPORT
Abstract:
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.
