3D-printing is growing each day with researchers discovering more ways to use it for various things. This time scientists have figured out a way to 3D-print more breathable tissues. Researchers at Pennsylvania State University have taken a step forward in making lab-made tissues such as bones and cartilages become a reality. They have created a method of fabricating porous tissues, in which micro-pores allow nutrients and oxygen to circulate, and thus keeping the cells healthy. This method requires taking human stem cells from human fat and then mixing them with a sodium alginate material found in seaweed. This can then be printed into particles that, once dissolved, leave small breathable pores in the fabric of the tissue, explained Digital Trends. Experts want to 3D-print skin, bones and other body parts to help astronauts Such porous structures allow both nutrients and other fluids to circulate and demonstrate the potential for […]
