I’d like to print collagen gels, basically Jello. I’ve got an extra printer I can modify, does anyone have suggestions?Obviously there are some challenges printing collagen since it polymerizes after pH neutralization. It would need to print into a solution of sodium hydroxide so that it polymerized on contact and it would have to go quite slow, probably 20mins per layer to give each layer time to polymerize. http://ift.tt/2cROXmV
