Three-dimensional (3D) printers are quickly becoming available to the masses. Soon, you and I will be printing on one of them. So what are they good for?
Our university has one. Apparently, you can build a gun with one of them. Now, soon, it seems, 3D printers will also be able to produce meat! Presumably, the meat and the gun will come from two different printers. Then again, why should that be an issue? Have you eaten at a fast food joint lately?
