Edit: Surprised at all the vegans in this thread. I didn’t think there were so many of you. I’m glad you care so much about animal rights, that you’re willing to forego eating them and using products made from them. If you’re not vegan and have moral objections for this, maybe you should look at yourself first and all the animal abuse you sanction by eating animals and using animal products. Did you know dairy cows have to be pregnant to produce milk? They’re artificially inseminated throughout most of their lives. I hope everyone complaining about this also complains about ice cream and cheese. Or else they would be hypocrites who just want to blame others but never look at themselves.
Some Scottish scientist has been working with 3D printing organs. I haven’t heard anything about it in a few years though. This is definitely cheaper, as he has to work with your specific stem cells and culture them to use as “ink”
