You may have heard of 3D-printing pens before: devices like the 3Doodler which turn plastic filaments into a gel that hardens in the air — letting users create impressive freehand sculptures in the process.
But while these are all well and great, new Kickstarter project Renegade wants to solve the accompanying problem of cost and waste which comes with having to buy often pricey filaments for the pens in question. In aid of this mission, creator Daniel Edwards has invented a 3D-printing pen that works by recycling household plastic waste such as plastic bottles, files, and bags.
“We often use 3D printing for our projects, so we were regularly exposed to the price of standardized filaments,” Edwards tells Digital Trends. “After paying $100 for a 3D pen and being obliged to buy its filaments for $10 per 50g pack, we couldn’t help but think this [was] crazy!” Edwards also notes that he is painfully aware of “the mountains of used plastic bottles and bags that continue to critically pollute our environment.”
