Greetings from the Print UV Conference in Las Vegas. Last night, I got a sneak peak of an interesting new substrate created by a new company called MicroGreen, that essentially recycles plastic water bottles into a light, highly printable polymer substrate—which itself can be recycled, potentially offering a “closed loop” system for producing substrates. It was really quite cool. There will be more on this—and other topics—in upcoming WhatTheyThink coverage of this conference.
