Abstract
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 the carrier () away from the build surface to form the three-dimensional object () from the solid polymer. The carrier () includes at least one retain and release () feature that is configured to: i) retain the three-dimensional object () formed from the solid polymer on the carrier () in a first state; and ii) facilitate release of the three-dimensional object () formed from the solid polymer from the carrier () in a second state.
