    摘要： The invention is a system and method for printing 3D objects that employs a hydraulic device. The device may comprise a cartridge or container assembly, which may be single-use or disposable. The container assembly may unitarily house a structure such as a piston, a platform, multiple chambers, and a channel, wherein the channel and chambers are fluidly connected and configured to hold enough of a 3D printing material suitable for printing a single 3D object. In exemplary embodiments, moving the piston transfers 3D printing material from one chamber to another chamber in which the platform is situated; radiation from a light engine coupled to the chamber that includes the platform exposes the 3D printing material to a curing light on a surface of the platform or onto a cured layer of the printing material on the platform, in order to build the 3D object on the platform.

    摘要： A system and method of adjusting a dental appliance by modifying a corresponding digital dental appliance model. The system includes an additive manufacturing system (e.g., a 3D printer system) and a controller running software. The system is designed to (i) 3D print a dental appliance using an initial digital dental appliance model, (ii) determine any portions of the printed dental appliance that may require modification, (iii) automatically adjust the appliance's digital model by performing pixel offsetting to implement a modification, and (iv) reprint the appliance using the modified digital model.

    摘要： The invention is generally a system for washing off residual resin from objects which are three-dimensionally (3D) printed through a vat polymerization (VP) process. Exemplary systems may include a solvent receptacle, a wash reservoir in fluid communication with the solvent receptacle, and a controller configured to pump a solvent from the solvent receptacle to the wash reservoir for washing off residual resin from a 3D-printed object. Exemplary methods may include pumping a first solution of a plurality of solvent solutions from the solvent receptacle to the wash reservoir, dispersing the first solution onto the 3D-printed object, pumping the first solution from the wash reservoir to the solvent receptacle, pumping a second solution of the plurality of solvent solutions from the solvent receptacle to the wash reservoir, and dispersing the second solution onto the 3D-printed object.
