HYDRAULIC 3D-PRINTING SYSTEM AND METHOD
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.
1 . A container assembly for printing a three-dimensional (3D) object, comprising:
an enclosure housing a first chamber adapted to store a printing material and a second chamber adapted to receive a platform;
a channel within the enclosure connecting a side wall of the first chamber with a side wall of the second chamber so that the first chamber and the second chamber are in fluid communication; and
a structure, movable within the first chamber adapted to transfer a portion of the printing material from the first chamber to a printing area between a surface of a window and the platform in the second chamber for receiving a curing light for curing a layer of the printing material onto the platform or onto a cured layer of the printing material on the platform, in order to build the 3D object on the platform.
2 . The container assembly of claim 1 , wherein the second chamber is adapted to limit or prevent a rotation of the platform.
3 . The container assembly of claim 1 , wherein the second chamber is a non-cylindrical chamber.
4 . The container assembly of claim 1 , wherein the second chamber includes a circular cross-section extending a first length along an axis of the second chamber, and a non-circular cross-section extending a second length along the axis of the second chamber.
5 . The container assembly of claim 4 , wherein the platform includes a cylindrical portion adapted to register with the circular cross-section extending the first length along the axis of the second chamber.
6 . The container assembly of claim 4 , wherein the platform includes a seal adapted to hermetically seal the circular cross-section extending the first length along the axis of the second chamber.
7 . The container assembly of claim 4 , wherein the second chamber includes one or more structures along one or more side walls adapted to alleviate a negative pressure during a movement of the platform.
8 . The container assembly of claim 7 , wherein the one or more structures includes a negative pressure cavity or air vents along the one or more side walls of the second chamber.
9 . The container assembly of claim 1 , further comprising a handle portion coupled to the platform for removing the platform from the second chamber to facilitate removal of the 3D object built onto the platform.
10 . The container assembly of claim 1 , wherein the enclosure is adapted to receive heat from a heat source external to the container assembly.
11 . A system for printing three-dimensional objects, comprising:
a controller;
a container assembly adapted to hermetically store a printing material, including:
an enclosure housing a first chamber adapted to store a printing material and a second chamber adapted to receive a platform;
a channel within the enclosure connecting a side wall of the first chamber with a side wall of the second chamber so that the first chamber and the second chamber are in fluid communication; and
a structure, movable within the first chamber adapted to transfer a portion of the printing material from the first chamber to a printing area between a surface of a window and the platform in the second chamber;
a motor coupled to the controller and configured to move the structure; and
a light emitting module, in communication with the controller, configured to emit a curing light through the window to cure at least a layer of the printing material to the platform or to a cured layer of the printing material on the platform, in order to build the 3D object on the platform.
12 . The system of claim 11 , further comprising an arm coupled to the motor and adapted to press on the structure of the container assembly.
13 . The system of claim 12 , further comprising a housing for the controller, the motor, and the light emitting module, an exterior surface of the housing including a holding frame adapted to receive the container assembly.
14 . The system of claim 13 , further comprising a touch screen interface disposed on an exterior of the housing.
15 . The system of claim 13 , further comprising a heating module adapted to heat the printing material inside the container assembly.
16 . The system of claim 15 , wherein the heating module comprises a transparent surface heater disposed over portion of the holding frame.
17 . The system of claim 15 , wherein the heating module includes a layer of an Indium Tin Oxide (ITO) coating.
18 . The system of claim 15 , wherein the heating module comprises an adapter removably coupled to the holding frame, the adapter having heating elements disposed on walls of the adapter.
19 . The system of claim 15 , wherein the heating module comprises a heating element disposed over the arm.
20 . A container assembly for printing a three-dimensional (3D) object, comprising:
a single-use enclosure housing a first chamber adapted to hermetically store a printing material and a second chamber adapted to receive a platform, wherein the second chamber is adapted to limit or prevent a rotation of the platform;
a channel within the single-use enclosure connecting a side wall of the first chamber with a side wall of the second chamber so that the first chamber and the second chamber are in fluid communication; and
a structure, movable within the first chamber adapted to transfer a portion of the printing material from the first chamber to a printing area between a surface of a window and the platform in the second chamber for receiving a curing light for curing a layer of the printing material onto the platform or onto a cured layer of the printing material on the platform, in order to build the 3D object on the platform.
