Device could help advance regenerative medicine. A UCLA Samueli-led team has developed a specially adapted 3D printer to build therapeutic biomaterials from multiple materials. The advance could be a step toward on-demand printing of complex artificial tissues for use in transplants and other surgeries. “Tissues are wonderfully complex structures, so to engineer artificial versions of them that function properly, we have to recreate their complexity,” said Ali Khademhosseini, who led the study and is UCLA’s Levi James Knight, Jr., Professor of Engineering at the UCLA Samueli School of Engineering...

Researchers at Carnegie Mellon University have developed a low-cost 3D bioprinter by modifying a standard desktop 3D printer, and they have released the breakthrough designs as open source so that anyone can build their own system. The researchers – Materials Science and Engineering (MSE) and Biomedical Engineering (BME) Associate Professor Adam Feinberg, BME postdoctoral fellow TJ Hinton, and Kira Pusch, a recent graduate of the MSE undergraduate program – recently published a paper in the journal HardwareX that contains complete instructions for printing and installing the syringe-based, large volume extruder (LVE) to modify any typical, commercial plastic printer.
