Systems and methods for stereolithography three-dimensional printing

A system for printing a three-dimensional (3D) object, comprising:

• at least one platform configured to hold a film of at least one mixture;
• a deposition unit comprising a nozzle in fluid communication with a source of said at least one mixture, wherein said deposition unit is configured to deposit said film onto said at least one platform;
• a building unit comprising a light source configured to provide a light sufficient for curing at least a portion of said film, to form at least a portion of said 3D object;
• a build head configured to hold said at least said portion of said 3D object;
• and
• a controller operatively coupled to said at least one platform, wherein said controller is configured to direct said at least one platform to move from said deposition unit to said building unit, or vice versa, along a plurality of non-overlapping paths.

A method for printing a three-dimensional (3D) object, comprising:

• (a) providing:
• (i) at least one platform for holding a film of at least one mixture;
• (ii) a deposition unit comprising a nozzle in fluid communication with a source of said at least one mixture, wherein said deposition unit is for depositing said film onto said at least one platform;
• (iii) a building unit comprising a light source for providing a light sufficient for curing at least a portion of said film, to form at least a portion of said 3D object;
• and
• (iv) a build head configured to hold said at least said portion of said 3D object;
• and
• (b) moving said at least one platform from said deposition unit to said building unit, or vice versa, along a plurality of non-overlapping paths.
