  • Patent number: 11123903
    Abstract: A method for manufacturing a breast implant includes producing an elastic filler material including foam, by applying a source of gas bubbles to a silicone monomer to create a mixture. The mixture is inserted into a sealed chamber. After inserting the mixture, a pressure inside the sealed chamber is set to a first pressure, and a temperature of the mixture inside the sealed chamber is set to a first temperature. Then, following a preset time duration, the pressure is lowered to a second pressure that is lower than the first pressure, and after a given time, the temperature is lowered to a second temperature that is lower than the first temperature. A flexible shell, configured for implantation within a breast of a human subject, is filled with the elastic filler material.

  • Patent number: 11104060
    Abstract: A long sheet may travel lengthwise through a fabrication system. The sheet may be much longer than it is wide or high. One or more objects that are being fabricated may be attached to the sheet. The sheet may move, step by step, through a vat of liquid photopolymer while a digital micromirror device projects a sequence of images unto a surface of the liquid. At each step, a projected light image may cure liquid photopolymer, thereby producing solid, cured polymer that becomes part of an object being fabricated. The sheet may be included in the final fabricated object, or may be a sacrificial material that is removed from the final fabricated object. Alternatively, the sheet may be in the shape of a loop. Or, the sheet may be detached from the final fabricated object and then fed through the system again.

  • Patent number: 11104117
    Abstract: An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. The apparatus includes a solidification substrate that is tiltable relative to a film about a tilting axis. Layers of the solidifiable material solidify in contact with a film located between the most recently solidified object layer and a solidification substrate that comprises the solidification substrate assembly. The tilting of the solidification substrate relative to the film allows the substrate to be used to squeeze excess solidifiable material from between the film and the most recently solidified object surface while minimizing or eliminating the formation of bubbles in the solidifiable material which can prolong object build times.
