Abstract:
A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween, with the carrier positioned adjacent and spaced apart from the build surface at a start position; then (b) forming an adhesion segment of the three-dimensional object (c) optionally but preferably forming a transition segment of the three dimensional object; and then (d) forming a body segment of the three dimensional object. In each case, the segment can be formed by: (i) filling the build region with a polymerizable liquid, (ii) continuously or intermittently irradiating the build region with light through the optically transparent, and (iii) continuously or intermittently advancing the carrier away from the build surface, to thereby form that segment from the polymerizable liquid.
