I looked at one of the links, but are these all printers that use various forms of plastics?
I was listening to a story on the radio just the other day, and the guy made the comment that anything that can be made into a powder, theoretically the proper 3D printer would be able to make the product out of.
Can only hope that means that powdered aluminum and steel 3D printers are coming (or are already out there) at a price many can afford.
Metal printers are already out there (though they are very expensive). Just been reading about a group of people who have designed a working gun that can be printed out, though the barrel has to be bought.
