Bioengineering, also known as biomedical engineering, is a field of engineering that applies engineering principles and techniques to the medical field. It involves designing and developing medical technologies and devices, such as artificial organs, medical imaging systems, and other medical innovations.

3D printed body parts, also known as bioprinting, is a technology that uses 3D printing to create living tissue and organs. This is done by using a 3D printer to deposit layers of living cells, growth factors, and other materials to create functional tissue structures. This technology has the potential to revolutionise the field of medicine by providing a new way to create replacement tissues and organs for patients in need. Some potential applications of 3D printed body parts include the creation of custom-made replacement skin for burn victims and the development of 3D-printed organs for transplantation.

3D printing capabilities continue to evolve with researchers constantly looking for ways to improve the technology.

MIT scientists may provide the latest boost to the technology with the invention of 3D manufactured “4D materials” that transform into much more complicated structures in response to changes in temperature and humidity. While much of the shape-changing is rudimentary—from flat to orbs and domes—the researchers have also managed to create a 4D human face.
