System and method for three-dimensional printing

1. A three-dimensional printing system, comprising:

a reservoir tank having a bottom surface and at least one side wall, the bottom surface and the at least one side wall which form an interior of the reservoir tank for storing one or more forming materials that are responsive to electromagnetic radiation of a defined range of wavelengths to form a solid material, the reservoir tank including a drum assembly having a hydrophobic material stretched between a top stretcher wall of the drum assembly and an inner wall of the bottom portion of the reservoir tank, and the stretched hydrophobic material is in the shape of a drum;

a projector to project electromagnetic radiation that includes the defined range of wavelengths towards the reservoir tank to cure a portion of the one or more forming materials stored in the reservoir tank to form in the reservoir tank at least a section of a solid object comprised of the solid material; and

a lifting platform moveable in a direction perpendicular to the bottom surface of the reservoir tank, the lifting platform configured to move the solid object perpendicularly away from the bottom surface after the section of the solid object is formed, whereby additional sections of the solid object can be formed in the interior of the reservoir tank; and

a wiper and/or a scraper coupled to the reservoir tank, the wiper and/or the scraper adapted to remove debris from the bottom surface.

2. The system of claim 1 , wherein:

the reservoir tank is further configured to tilt in relation to the lifting platform in order to separate a cured portion of the one or more forming materials from the bottom surface of the reservoir tank.

3. The system of claim 2 , further comprising:

a passive hinge coupled to the reservoir that enables the reservoir tank to be tilted and returned to an initial position by the movement of the lifting platform during one or more printing cycles of the system.

4. The system of claim 2 , further comprising:

a motor coupled to the reservoir tank and configured to tilt the reservoir tank and to return the reservoir tank to an initial position during one or more printing cycles of the system.

5. The system of claim 2 , further comprising:

a feedback system configured to obtain an accurate position of the reservoir tank so that the reservoir tank tilts into a same location during one or more printing cycles of the system.

6. The system of claim 5 , wherein:

the feedback system comprises of one or more sensors or one or more servo motors.

7. The system of claim 1 , wherein:

the reservoir tank comprises a single-use drum assembly having a protective seal to enclose the one or more forming materials inside the reservoir tank.

8. The system of claim 1 , wherein the projector is operable to project electromagnetic radiation in a range of 365 nanometers to 410 nanometers.

9. The system of claim 1 , wherein projector is operable to project electromagnetic radiation in a range of 405 nanometers to 410 nanometers.

10. The system of claim 1 , wherein the bottom surface of the reservoir tank is transparent to electromagnetic radiation in at least the defined range of wavelengths, and the projector is orientable to project the electromagnetic radiation into the reservoir tank via the bottom surface.

11. The system of claim 1 , further comprising:

a controller including at least one processor and at least one nontransitory processor-readable medium that stores at least one of processor-executable instructions and data, which when executed by the at least one processor, cause the at least one processor to iteratively;

cause the projector to project spatial pattern of the electromagnetic radiation into the reservoir tank to form each of respective additional section of the solid object; and

cause the lifting platform to move away from the bottom of the reservoir tank as each of respective additional section of the solid object is formed.
