摘要： A device for keeping the liquid level constant during 3D printing includes a liquid bath for containing printing liquid, a printing platform for carrying a printed sample, a liquid level counterbalance inserted into the liquid bath, and a link mechanism connected with the printing platform and the liquid level counterbalance respectively for driving the liquid level counterbalance to ascend when the printing platform descends. The printing platform is inserted into the liquid bath and driven by a lifting device to ascend or descend. The printing platform and the liquid level counterbalance are in a relationship that a volume of a portion of the printing platform immersed into the printing liquid due to descending of the printing platform is equal to a volume of a portion of the liquid level counterbalance leaving the printing liquid due to rising of the liquid level counterbalance caused by descending of the printing platform.

摘要： Methods and compositions for additive manufacturing of silicone parts are provided. The methods can use SLA printing techniques to print silicone parts that exhibit excellent hardness, tear strength and elongation at break. The parts can be produced by using low dosages of radiation. In various embodiments, the silicone compositions include a mercapto-derivatized polysiloxane having two or more functional groups, an alkenyl-derivatized polysiloxane, and a photo-initiator.

摘要： An additive manufacturing apparatus is provided herein that includes a resin support configured to support a resin. A support plate includes a window. A stage is configured to hold one or more cured layers of the resin to form a component. Each cured layer is formed with the stage in a respective cure position. A radiant energy device is positioned on an opposite side of the resin support from the stage and is operable to generate and project radiant energy in a patterned image through the window. An actuator is operably coupled with the stage and is configured to move the stage in a Z-axis direction to place the stage in a removal position. The component contacts one of the resin support or the resin supported by the resin support in the removal position.
