Don't get me started on 3D printers. I work for an invisible braces company. Do you know how much waste is generated from 3D printing? Hey everyone's teeth are straight but the landfills are full of plastic.

I don't understand. Can't that plastic be re-used?

They heat plastic up to stamp it over model of printed teeth.  I've been told that type of plastic isn't recyclable once heated.  Pretty much everything is trash there and nothing is recycled.  Those printed models of teeth end up in trash too.  Only thing not sent to trash is the end product of clear braces.
