From: Recent advances in bioprinting techniques: approaches, applications and future prospects

Bioprinted tissues and organs 3D printing technology Applications Future directions References
Blood vessels Inkjet bioprinting Optimizing vascular geometry and cell viability and function Predicting flow rates, oxygen tension, and the diffusion of molecules in the vascular environment Improving resolution for printing small vessels Increasing available bioink materials Increasing bioprinting speed [22, 111]
Extrusion bioprinting
Laser-assisted bioprinting
Heart Extrusion-based bioprinting Printing valvular interstitial cells into scaffolds with high speed and good viability (~100 %) over 21 days Printing hydrogel-based valve-shaped structures Developing types of materials with good flexibility and elasticity [31, 77, 83]
FRESH
Bone SLA Printing scaffolds that provide a framework for cells to attach, proliferate and function and to be integrated with the surrounding tissue Accurately controlling pore geometry, cell viability and mechanical properties Investigating printed materials with osteoinductive or osteoconductive proteins Triggering vascularization in the repaired region [112, 113]
Laser-assisted bioprinting
Liver Inkjet printing Printing biological livers for liver transplantation in patients with liver resection Constructing artificial liver tissue for the detection of drug toxicities and other medical and biological testing Constructing 3D functional liver tissue with a substantial capillary-like network [95, 99, 114]
Skin Inkjet bioprinting Fabricating skin substitutes to repair skin wounds Studying the pathophysiology of skin diseases Fabricating more complex human skin models with secondary and adnexal structures Improving LAB technology to achieve automation for bioprinting skin [42, 93]
