CMU Engineers Find Innovative Way to Make a Low-Cost 3D Bioprinter
“Researchers at Carnegie Mellon (CMU) are beginning to crack the code of large-scale, low-cost bioprinting while preserving the quality of a detailed print. Their printer? A standard MakerBot desktop 3D printer, modified over six years with open-source hardware and software, now capable of printing lab-grown cells, including collagen and other extracellular matrix proteins. A novel technique specifically designed to print soft and living materials, CMU’s Freeform Reversible Embedding of Suspended Hydrogels (FRESH) prints tissue in a gel, which is then carefully melted away to guarantee the viability of cells. CMU’s engineers have made their bioprinter designs open source — now buildable for under $500 — enabling new medical collaborations and democratized access…”
