An interesting article by Ardar Uddin. Recently, 3D printing technology has generated immense interest in regenerative medicine and tissue engineering. Scientists have been able to engineer human tissues with viable cells embedded inside 3D printed constructs, through a process known as bioprinting (3D Organ Printing).
Different methods have been devised for 3D printing such as stereolithography (SLA)1, selective laser sintering (SLS)2, fused deposition manufacturing (PIP)3 and liquid-frozen deposition manufacturing (LFDM)4. The basic idea behind all the methods is molding cellular aggregates commonly known as “bioink” and polymer to form a 3D structure imitating 3D scanned tissue or organ.
Bioprinting has immense translational promise in which 3D printed organs could potentially be used for medical transplantation, reducing the risk of immune rejection and increasing organ availability. Furthermore, 3D printed tissues would provide a robust screening tool to test efficacy of different drugs and treatments, significantly improving our current methods of in vitro testing. Read more…
