Abstract
The present disclosure provides methods and systems for printing a three-dimensional (3D) material. In some examples, a method for printing a 3D biological material comprises providing a media chamber comprising a medium comprising (i) a plurality of cells and (ii) one or more polymer precursors. Next, at least one energy beam may be directed to the medium in the media chamber along at least one energy beam path that is patterned into a 3D projection wherein the x, y, and z dimensions may be simultaneously accessed in accordance with computer instructions for printing the 3D biological material in computer memory, to form at least a portion of the 3D biological material comprising (i) at least a subset of the plurality of cells, and (ii) a polymer formed from the one or more polymer precursors.
Claims21
A system for printing a three-dimensional (3D) object, comprising:
- a media chamber that contains a medium comprising one or more polymer precursors;
- at least one pulsed energy source to output at least one pulsed energy beam to said media chamber;
- and
- one or more computer processors operatively coupled to said at least one pulsed energy source, wherein said one or more computer processors are individually or collectively programmed to
- (i) receive computer instructions for printing said 3D object from computer memory;
- (ii) receive a computer model of the 3D object in the computer memory;
- and
- (iii) in accordance with said computer instructions and the computer model of the 3D object, direct said at least one pulsed energy source to output said at least one pulsed energy beam into said medium, wherein the at least one pulsed energy beam simultaneously generates a plurality of points or lines patterned as a 3D holographic projection of multiple layers of said 3D object in a volume of said medium, thereby subjecting said polymer precursors to form a polymer matrix at the multiple layers at the same time to form said 3D object.
