A recent advancement out of Penn State allows for 3D printed porous tissue. One of the biggest hurdles of fabricating living tissue is replicating blood vessels and porous textures. 3D printing is well suited to create those complex structures as multiple materials can be mixed or positioned in specific geometries, even on the inside of an object . Still, even with 3D printing, there remain obstacles, and one of those is size. Ibrahim Ozbolat, associate professor of Engineering Science and Mechanics at Penn State, explains, “One of the problems with fabrication of tissues is that we can’t make them large in size. Cells die if nutrients and oxygen can’t get inside.” As the science of creating blood vessels is still nascent, most fabricated tissues are kept small enough that researchers can manually deliver nutrients where they’re needed. If a piece of tissue is volumetrically large, it’s difficult to get […]
