Wake me up when we can 3D print pills and I can craft the perfect Tylenol or 5 hour energy from some React app. Now that'll be a medical revolution!

You don't need a 3D printer. Just order bulk acetaminophen and caffeine powder, then put as much as you want into capsules. (Don't poison yourself.)

Once this is done, printing chemicals might be achievable too (thanks to the network effect of lots of people already having 3d printer to produce the required hardware), but maybe not immediately :)
