Abstract
A bioprintable material is provided. The bioprintable material includes a hydrogel and microfilaments mixed in the hydrogel. The hydrogel includes a first collagen. The microfilament includes a second collagen. The diameter of the microfilament is ranging from 5 microns to 200 microns. The weight ratio of the microfilaments to the first collagen is ranging from 0.01:1 to 10:1.
Claims20
A bioprintable material, comprising:
- a hydrogel comprising a first collagen;
- and
- a microfilament comprising a second collagen mixed in the hydrogel, wherein the microfilament has a diameter of ranging from 5 μm to 200 μm, and the microfilament and the first collagen have a weight ratio of ranging from 0.01:1 to 10:1.
A method for fabricating a bioprintable material, comprising:
- providing a second collagen to perform a filament-forming step to form a microfilament;
- and
- mixing the microfilament and a hydrogel to produce a bioprintable material, wherein the hydrogel comprises a first collagen, the microfilament has a diameter of ranging from 5 μm to 200 μm, and the microfilament and the first collagen have a weight ratio of ranging from 0.01:1 to 10:1.
