brave new world we're living in
I understand how 3D printing works, but trying to sit down and think about it hurts my brain.
brave new world we're living in
we're probably a couple of decades away from printing a live human being cell by cell
what are the religious nuts gonna say then
everyone will be their own personal god.....capable of creating anything they can dream of
anymore. 
Its very simplistic actually. I've operated one. You have a device that looks like an easy bake oven. Inside of it are large *how do i say this* like ink cartridges that have material used to create the 3d image. You use some kind of cad drawing software of some kind to create a model for what you want to print. You then export the file to the printer and the print head goes up and down inside the little oven tray and creates the image for you using the material in the cartridges. The material hardens quickly so you can easily bring your ideas to beta form. Very cool to watch.

what makes you think we know what an easy bake oven looks like?
Dont be aggressive with me, friend. We all have female cousins, nieces, sister who may have owned a makeshift oven to make basic snacks for us. Im kinda surprised you didnt.

I want to stick my hand in one while its printing smh
It would be like you sticking your hand on someones skin while their getting a tattoo. You'd literally be putting your hand under the ink head as its on their skin. Probably painful.
I had a dream i did and it was just plastic that bounced off![]()
The unit feels like it has some weight to it. It will probably draw a piece of the figure in your skin.

Earlier this week, an un-named man in the United States had 75 percent of his skull replaced with a 3D-printed plastic prosthetic, the first-known operation of its kind. The transplant was carried out by Oxford Performance Materials, which received approval to carry out such procedures from the US Food and Drug Administration last month. The company crafted the artificial skull based on a 3D scan of the patient's head, and the polyetherketoneketone prosthetic sports holes meant to encourage the growth of new cells and bone. According to the firm, about 500 people in the US could benefit from this technology each month. It's a fascinating implementation of a technology that's better associated with figurines and animation, but here's hoping we never witness the innovation firsthand.
