Researchers from Imperial College London (ICL) have developed new 3D Printing Technique to create biological replicas for tissue regeneration. In collaboration with Kings College London, they experimented with 3D Printing and Cryogenics using solid Carbon Dioxide (dry ice) to quickly cool down hydrogel ink and Ultimaker 3D Printer. Once the ink softens, it forms a gel as soft as human tissue, which was then seeded with Dermal Fibroblasts with success.
