The 3D printing industry had a little controversy. This controversy revolves around a small startup in the Allentown, PA area called “Just3DPrint”. Company is founded by four college students who had a dream, “offer 3d printing services”. The controversy does not revolve around their printing service, but it involves two powerhouses, Thingiverse; a website that allows 3d modelers to share their creations for “free” in a non-commercial manner and Ebay, the largest auction website in the world.
