Abstract: A three-dimensional (3D) printing system for manufacturing a 3D article includes a resin vessel, a build tray, a movement mechanism, a light engine, a housing, a gas handling system, and a controller. The resin vessel includes a transparent sheet on a lower side. The housing defines two chambers including an upper chamber and a lower chamber. The upper chamber is in fluidic communication with the resin contained by the resin vessel. The lower chamber is in fluid communication with a lower surface of the transparent sheet. The controller is configured to (a) operate the gas handling system to reduce and control a partial pressure of oxygen in the upper and lower chambers, (b) operate the movement mechanism and the light engine to form the 3D article in a layer-by-layer manner.

Abstract: An article is configured for transferring tissue cores from a patient donor site to a patient wound site. The article includes a matrix construction of resilient elastomeric polymer material to support an array of tissue core locators individually defining an opening and individually configured to: (1) receive a tissue core from the donor site into the opening, (2) resiliently hold the tissue core at the opening until and after the sheet is placed upon the wound site, and (3) release the tissue core when the sheet is removed from the wound site at a time that is between 2 and 29 days after the sheet is placed upon the wound site.

In some embodiments, an ink described herein comprise 10-70 wt. % or 20-40 wt. % of a cyclopolymerizable monomer, based on the total weight of the ink. The cyclopolymerizable monomer comprises an acrylate moiety and an ethenyl or ethynyl moiety, and the α-carbon of the acrylate moiety and the α-carbon of the ethenyl or ethynyl moiety may have a 1,5-, 1,6-, 1,7-, or 1,8-relationship. Additionally, an ink described herein can have a viscosity of 1600 centipoise (cP) or less at 30° C., or of 500 cP or less at 30° C. and can be used to print a desired 3D article having mechanical properties similar to those of articles formed from thermoplastic materials.

Abstract: There is provided compositions and methods for producing three-dimensional objects by selective deposition modeling with a polar build material and a non-polar support material. The build material comprises a hydrocarbon wax material and a viscosity modifier, and the support material comprises a hydrocarbon alcohol wax material and a viscosity modifier. After the selective deposition modeling process has been completed, the object can be placed in a bath of polar solvent to remove the support material. The particular materials provided herein, and the post-processing methods associated therewith, provide for improved part quality of the three-dimensional object and for improved post-processing techniques. The three-dimensional objects can subsequently be used in a number of applications, such as patterns for investment casting.
