Method and apparatus for three-dimensional fabrication

The present invention relates to methods and an apparatus for the fabrication of solid three-dimensional objects from liquid polymerizable materials.. . ... Carbon3d Inc

Method and apparatus for three-dimensional fabrication

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.. ... Carbon3d Inc

Continuous three dimensional fabrication from immiscible liquids

A method of forming a three-dimensional object is carried out by: providing a carrier and a pool of immiscible liquid, the pool having a liquid build surface, the carrier and the liquid build surface defining a build region therebetween; filling the build region with a polymerizable liquid, wherein the immiscible liquid is immiscible with the polymerizable liquid (in some embodiments wherein the immiscible liquid has a density greater than the polymerizable liquid); irradiating the build region through at least a portion of the pool of immiscible liquid to form a solid polymer from the polymerizable liquid and advancing the carrier away from the liquid build surface to form the three-dimensional object comprised of the solid polymer from the polymerizable liquid. Optionally, but in some embodiments preferably, the method is carried out while also continuously maintaining a gradient of polymerization zone between the liquid build surface and the solid polymer and in contact with each thereof, the gradient of polymerization zone comprising the polymerizable liquid in partially cured form.. ...
