Abstract
The disclosure relates to a method or a platform for hydrogel-based 3D fabrication, wherein the hydrogel is patterned with a programmable femtosecond light sheet with a power density of 0.1 to 100 TW/cm2.
Claims10
A method for hydrogel-based 3D fabrication, comprising:
- patterning a hydrogel with a laser with a power density of 0.1 to 100 TW/cm2 by a photo-chemical modification of the hydrogel;
- shrinking the hydrogel, then depositing and absorbing a material on the hydrogel, wherein the material is directly bonded to the hydrogel;
- dehydrating the hydrogel to produce a three-dimensional structure.
