Abstract
Described are systems and methods for multi-material printing. The systems and methods can utilize a stereolithographic printing device, a moving stage, and a microfluidic device. The microfluidic device can include a plurality of reservoirs, each reservoir housing a different ink for printing, and a microfluidic chip. The microfluidic chip can include a chamber that comprises a plurality of inlets, a printing region, and one or more outlets as well as an elastic membrane.
Claims6
A method of printing a multi-material 3D construct comprising:
- providing a plurality of inks;
- releasing at least one first ink into a microfluidic chip wherein the microfluidic chip comprises (i) a chamber, wherein the chamber further comprises a printing region for holding the ink to be printed;
- (ii) a deposition layer, and (iii) an elastic membrane;
- causing the elastic membrane to deform;
- photocrosslinking the first ink in the printing region onto the deposition layer to form a first printed layer;
- reducing the deformation of the elastic membrane;
- washing the chamber;
- and
- releasing at least one second ink into the microfluidic chip to produce a second printed layer.
