Scientists at Harvard University used 3D printed brain to learn how a human brain develops it's folds. The whole new concept that not only biochemical processes but physical forces are also involved in brain folds formation. This new discovery will help better understand the concepts behind neurological disorders like Alzheimer's disease and Schizophrenia.

With 3D Printing already into use in every sector, researchers are now experimenting 4D Printing that involves 3D-printing items that are designed to change shape after they are printed. Lewis and team, Harvard University, have evolved 3D-printed structures made of stiff cellulose fibers embedded in a soft hydrogel, whose orientation can be controlled after they swell up on immersing in water.

A team of researchers in tissue engineering, 3D biofabrication, biomaterials design and stem cell differentiation at Harvard’s Wyss Institute is working on 3D Printing a Functioning Kidney Subunit with current work to build branched vascular network unique to each organ. Using advanced 3D Bioprinting from Wyss Institute, Dr. Jennifer Lewis’s organ-on-chips are ready, using special polymer inks for creation of structures made up of human cells, complete with vasculatures and extracellular matrices.

Linh Nam, a Harvard College Student was diagnosed with Osteosarcoma, a cancerous tumor in the bone when she was just ten years old and had a section of bone removed from her leg with a gap left and upcoming 10 surgeries over a decade. However, she joined with Hala Zreiqat, biomedical engineering professor, to work on a project that aims to create a biocompatible, artificial material with the same strength and porosity as real bone using 3D printing. Professor Zreigat’s team finally found a way to generate a porous core of a novel multi-component ceramic for bone implants using 3D printing which will be available to public around 2019.
