Skip to 0 minutes and 9 secondsLast week, we used 3D printing to create implants. And again you will have seen the importance of identifying the need, creating the design, selecting the materials, and choosing the best 3D printing method. This week, we will confront new challenges. We will see where we are with the use of 3D-printed structures to facilitate tissue regeneration. Can we regenerate cartilage? Can we regenerate skin? To do so, we will need to 3D-print stem cells and biologically active molecules.
Week 3 introduction
Since the 1990s a new concept known as ‘tissue engineering’ has generated much excitement.
This is the possibility of replacing faulty tissues and organs with a fully-functional tissue or organ grown externally using the patient’s own cells.
Biomaterials, bionics and tissue engineering are relatively new fields and advances in these arenas are seen as pivotal to a new wave of medical practice. The recent concurrence of advances in these fields, in particular the development of highly biofunctional materials and the advent of 3D printing tools, has us poised on the verge of a revolution.
- What do you know of tissue regeneration? Have you heard of this before? If so where?
