This disclosure presents an ink for glass inkjet printing and its preparation method, comprising the following components by weight: 18-25 parts pigment; 30-40 parts glass powder frit; and 30-50 parts dispersion. The pigment is copper chromium black, and the dispersion includes a solvent, a dispersant, and additives. This ink has low viscosity and excellent flowability, allowing for smooth printing of complex patterns. It effectively suppresses diffusion, and combined with the high blackness of the copper chromium black pigment, it provides high pattern clarity.

The invention belongs to the technical field of bio-printing, and particularly discloses bio-ink of light-curable Matrigel matrigel, a preparation method and application in volume bio-printing.The bio-ink is prepared by mixing hydrogel and Matrigel matrigel and then adding a photoinitiator, controllable curing can be achieved under irradiation of a light source, and the bio-ink has the advantages that the bio-ink can be applied to volume bio-printing; the problem that in the prior art, due to the fact that Matrigel matrigel lacks photosensitive groups, photo-crosslinking reaction cannot be carried out is solved, the bio-ink is further mixed with a biological medium, the composite bio-ink is obtained and perfectly compatible with the GLVBP technology, a printed and formed structure has high precision, high cell viability and good biocompatibility, and the composite bio-ink can be used for preparing the light-sensitive matrix gel. The method has a wide application prospect in the biomedical fields of organoid culture, tissue engineering and the like.
