摘要： A method of forming a three-dimensional object useful as a casting mold is carried out by 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 liquid photocurable ceramic resin; irradiating the build region 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, while also concurrently with the irradiating and/or advancing steps: (i) continuously maintaining a dead zone of polymerizable liquid in contact with the build surface, and (ii) continuously maintaining a gradient of polymerization zone between the dead zone and the solid polymer and in contact with each thereof. The gradient of polymerization zone comprises the polymerizable liquid in partially cured form (e.g., so that the formation of fault or cleavage lines between layers of solid polymer in the three-dimensional object is reduced). Apparatus for carrying out the method is also described.

摘要： 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.
