Abstract: There is provided solid imaging methods and apparatus for making three-dimensional objects from solid imaging material. A tray with a film bottom is provided to hold solid imaging material that is selectively cured into cross-sections of the three-dimensional object being built. A coater bar is moved back and forth over the film to remove any uncured solid imaging material from a previous layer and to apply a new layer of solid imaging material. A sensor is provided to measure the amount of resin in the tray to determine the appropriate amount of solid imaging material to be added, from a cartridge, for the next layer. A shuttle, which covers the tray when the exterior door to the solid imaging apparatus is opened for setting up a build or removing a three-dimensional object, can also be used to move the coater bar and to selectively open one or more valves on the cartridge to dispense the desired amount of solid imaging material.

Abstract translation: 提供了用于从固体成像材料制造三维物体的固体成像方法和装置。 提供具有薄膜底部的托盘以保持固体成像材料，其被选择性地固化成正在建造的三维物体的横截面。 涂膜机棒在膜上来回移动以从之前的层去除任何未固化的固体成像材料并施加新的固体成像材料层。 提供传感器以测量托盘中的树脂量，以确定用于下一层从盒中加入的固体成像材料的适量。 当打开固体成像装置的外门打开以建立构件或移除三维物体时，覆盖托盘的梭子也可用于移动涂布机杆并选择性地打开一个或多个阀 盒以分配所需量的固体成像材料。

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.
