Patent number: 10668709Abstract: A method of forming a three-dimensional object (17) includes: providing a carrier (18) and an optically transparent member (15) having a build surface, the carrier (18) and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid (16); irradiating the build region with light (12) through the optically transparent member (15) to form a solid polymer from the polymerizable liquid; and advancing the carrier (18) away from the build surface to form the three-dimensional object (17) from the solid polymer. The carrier (18) includes at least one retain and release (34) feature that is configured to: i) retain the three-dimensional object (17) formed from the solid polymer on the carrier (18) in a first state; and ii) facilitate release of the three-dimensional object (17) formed from the solid polymer from the carrier (18) in a second state.Type: GrantFiled: August 12, 2015Date of Patent: June 2, 2020Assignee: Carbon, Inc.Inventors: Alexander Ermoshkin, David Shirvanyants, Joseph M.

Patent number: 10661501Abstract: A method of forming a three-dimensional object includes: providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid, irradiating the build region with light through the optically transparent member to form a solid polymer from the polymerizable liquid, and advancing said carrier away from said build surface to form said three-dimensional object from said solid polymer. The irradiating step includes projecting focused light at the build region, and the advancing step is carried out at a rate that is dependent on an average light intensity of the focused light. An apparatus to perform the method is also disclosed.Type: GrantFiled: June 18, 2015Date of Patent: May 26, 2020Assignee: Carbon, Inc.Inventors: Joseph M.
