Instead of printing stupid shyt why don't they print money or Jordan's or replicate a PlayStation or drugs something useful I'd be doing fake ids and shyt
Printing money is highly illegal, plus your gonna need the right paper, watermarks, barcodes, texture of the paper, inking process, uv markers...
Jordans you can do but the materials and gonna be sued by copyright laws if you dont differentiate..
Drugs you can make in a chemist lab, you cant 3D print them...

it's not that advanced yet...
