A method of forming a three-dimensional object is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

Methods for producing three-dimensional objects

Provided herein is a resin product useful for the production of three-dimensional objects by additive manufacturing, and methods using the same. The resin may include a reactive blocked prepolymer comprising a prepolymer blocked with reactive blocking groups; a polyol; a photoinitiator; and at least one organometallic catalyst. A packaged product useful for the production of three-dimensional objects by additive manufacturing, the product comprising a single container having a single chamber and a resin in the chamber with all components mixed together, is also provided.

Dual cure resins for additive manufacturing

A method of forming a three-dimensional object, wherein said three-dimensional object is an insert for use between a helmet and a human body, is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

Methods for producing footwear with materials having multiple mechanisms of hardening

A method of forming a three-dimensional object, comprising: providing a carrier () and an optically transparent member having a build surface, said carrier () and said build surface defining a build region therebetween; filling said build region with a polymerizable liquid, continuously or intermittently irradiating said build region with light through said optically transparent member to form a solid polymer from said polymerizable liquid, continuously or intermittently advancing (e.g., sequentially or concurrently with said irradiating step) said carrier () away from said build surface to form said three-dimensional object from said solid polymer, said optically transparent member comprising a flexible layer () having upper and lower opposing sides, wherein the flexible layer () upper side defines the build region, the method further comprising forming a region of reduced pressure adjacent the flexible layer () lower side.

Three-dimensional printing with reduced pressure build plate unit

A method of making a three-dimensional object is carried out by: (a) providing an apparatus comprising a radiation source, a carrier on which the three dimensional object is made, and a movable belt positioned therebetween, the belt having a first surface and an opposite second surface, with the belt comprised of an optically transparent material, and with the belt permeable to a polymerization inhibitor; (b) applying a polymerizable liquid to the first surface of the belt, and contacting the second surface of the belt to the polymerization inhibitor, (c) contacting a portion of the belt first surface having the polymerizable liquid thereon to the carrier or the three dimensional object so that the belt adheres thereto with the polymerizable liquid positioned therebetween; (d) irradiating the polymerizable liquid with actinic radiation through the belt from the radiation source to polymerize the polymerizable liquid positioned therebetween; then (e) optionally separating the belt from the carrier or the three dimensional object; and then (f) repeating steps (b) through (e) until the three dimensional object is completed. Apparatus for carrying out the method is also described.

Method and apparatus for three-dimensional fabrication

A build plate unit () for a three-dimensional printer includes a build plate () having an optically transparent member comprising a flexible, gas permeable, optically transparent sheet () having upper and lower opposing sides, wherein the flexible sheet upper side defines the build surface; and a flexible, gas permeable or impermeable, optically transparent base layer () on the lower side of the flexible sheet opposite the build region, wherein the build plate is configured to permit gas flow to the build surface.
