摘要： A method of forming a three-dimensional object comprised of a silicone polymer is carried out by: (a) providing a silicone dual cure resin; (b) forming a three-dimensional intermediate from that resin, where the intermediate has the shape of, or a shape to be imparted to, the three-dimensional object, and where the resin is solidified in that intermediate object by irradiating with light; and then (c) further reacting the three-dimensional intermediate to form the three-dimensional object. The silicone dual cure resin includes: (i) a light polymerizable first reactant; (ii) a photoinitiator; (iii) at least one additional reactant(s), and (iv) optionally a catalyst. At least one of the first reactant and the additional reactant(s) contains a siloxane linkage.

摘要： Methods and apparatus for additive manufacturing of three-dimensional objects from polymerizable liquids are described. The methods and apparatus are implemented in the form of a bottom up additive manufacturing apparatus, and in preferred embodiments are implemented in the form of Continuous Liquid Interface Production (or “CLIP”) methods and apparatus. Rotation of at least one of the carrier and the build plate is preferably included, for example to facilitate the filling of the build region with the polymerizable liquid.

摘要： A method of forming a dual cure three-dimensional object by additive manufacturing may be carried out by mixing a first precursor liquid and a second precursor liquid to produce a polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component (e.g., a second reactive component) that is different from the first component (e.g., that does not contain a cationic photoinitiator, or is further solidified by a different physical mechanism, or further reacted, polymerized or chain extended by a different chemical reaction). In the foregoing: (i′) at least one reactant of the second solidifiable component is contained in the first precursor liquid, and (ii′) at least one reactant or catalyst of the second solidifiable component is contained in the second precursor liquid. Once mixed, the three-dimensional object may be formed from the resin by a dual cure additive manufacturing process.

摘要： 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.
