The bioprinting project has two general objectives: the development and adaptation of biological materials to make them usable in 3D printers, and the use of these and other materials to further research in tissue engineering and regenerative medicine.
Bio-Based materials: Our current research is centered on chitosan and collagen. Both are readily available, low cost, biodegradable materials. As well as providing an ecological alternative to current SLA printing resins, they have several biocompatible properties that make them ideal for use in tissue engineering and organ printing.
Tissue engineering: We have been working in collaboration with EpiBone, a Brooklyn based biotech company. EpiBone is studying how to grow bones from patient’s stem cells. We developed a polyethylene glycol based resin that is printable on an SLA printer as well as being a bioinert material that stem cells can adhere to. Working in conjunction with Meshmixer and Autodesk Within, we have printed a porous scaffold with the PEGDA resin that mimics the structural conditions within actual bone.
