I just wanted to add this to the materials wishlist..
Perhaps someone has already requested it?
Would it be possible to use SLS / Objet ( / some form of binder-printing followed by furnace treatment) to do 3D-printing in PET plastic?
It would probably not be glass-clear but it would still be cool to have a diffused/matte look.
It could also help as a "recycling"-target for PET product;
just turn it into dust and use it in a 3D printer
It's clearly possible to colour PET plastic so that would be a nice feature too.. translucent colored objects of your own design
It seems to have a pretty high meltingpoint (around 250 degrees Celcius) but maaaybe.. just maaaybe it's possible to get it heated up just enought to squeeze it out of a printer nozzle into a cooling bed of supportmaterial?
