3D printers post #2

i learned that they have 3D printers witch i didn't even know they did cause i dont watch a lot on technology, i learned that the larger the object being printed the longer it takes, i also learned that these 3D printers are very expensive, i like how you can print 3D toys like starwars battles ships, but i dont like how long it takes to print the items. How long till everyone has a 3D printer? thats my only question.
