3D Bioprinting

3D bioprinting is an additive manufacturing technique. It employs computer-aided design (CAD) software to design intricate three-dimensional structures and utilizes this technique to fabricate cell-based scaffold structures. The essence of 3D bioprinting technology lies in the use of living cells, bioactive factors, and biomaterials as fundamental building blocks to design and manufacture bioactive artificial organs, implants, or three-dimensional cellular structures.Bioink, the scaffold material used in 3D bioprinting, simulates the extracellular matrix (ECM) environment to facilitate cell adhesion, proliferation, and differentiation post-printing.
MCE provides natural polymer hydrogels and organic synthetic polymer hydrogels. Based on the differences in crosslinking methods, they can be further classified into light- cured modified hydrogel and thermosensitive hydrogel.
