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: A system for manufacturing a three-dimensional article includes a resin vessel, a vertical movement mechanism, and a light engine. The resin vessel includes a lower opening closed by a transparent sheet. The vertical movement mechanism is for positioning a support tray which supports the three-dimensional article. The light engine is disposed below the transparent sheet and is configured to selectively harden layers of resin over a build plane above the transparent sheet. The light engine includes a light bar coupled to a lateral movement mechanism. The light bar includes an array of light emitting devices and a device for impinging upon the transparent sheet. The impingement maintains a proper operating distance H between the transparent sheet and the build plane.

Abstract: A three dimensional printer includes a vessel, a light engine, a fixture, a movement mechanism, a sensor, and a controller. The vessel is for containing a liquid photocurable resin and includes a transparent sheet defining a lower surface through which the resin can be illuminated. The light engine is disposed and configured to selectively illuminate the resin through the transparent sheet. The fixture is for supporting a three dimensional article of manufacture having a lower face immersed in the resin in facing relation with the transparent sheet. The movement mechanism is configured for controllably translating the fixture to adjust a vertical height of the lower face above the transparent sheet. The sensor is configured to monitor a transient displacement of the transparent sheet during the translation.

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.
