3d print meniscus Researchers from North Carolina State University recently developed a technique that uses ultrasound to align cells in 3D bioprinted gels. Using this method, the team aims to bolster the quality of these tissues compared to the structures they are designed to replace. Ultimately, the goal is for these 3D printed tissues to treat common injuries. “We’ve reached the point where we are able to create medical products, such as knee implants, by printing living cells,” said corresponding author Rohan Shirwaiker, associate professor in NC State’s Edward P. Fitts Department of Industrial & Systems Engineering. “But one challenge has been organizing the cells that are being printed, so that the engineered tissue more closely mimics natural tissues.” The scientists built an ultrasound chamber that imposes ultrasound waves through the 3D printing area containing living cells. These waves travel through the printing region and are reflected back to […]
