From hobbyists, to providing goods for consumers in remote areas, the applications of 3-D printing are endless. The only problem: All 3-D printed products are made using petroleum based plastics, and lots of it. 3-D printing has eaten up 30 million pounds of plastic so far, which will translate to over a million barrels of oil used by 2020 with the current method of printing. A new company, called Dimension Polymers, recycles plastic to make the plastic spools used by 3-D printers. And if launched as planned, Dimension Polymers envisions their plastics reducing emissions related to 3-D printing plastics as much as 60 percent. For now Dimension Polymers is seeking Kickstarter funding, to make a large batch of recycled plastics to get their company off the ground.
