3D Printing pen to recycle plastic waste for filament

3D printer pens are no strangers to us. Pens like 3doodler and LIX has enticed us before with their ability to create sculptures out of drawings by using a gel that hardens when exposed in air. While 3D printing pens including the above mentioned ones demand expensive filaments to be refilled with, Renegade, a new 3D printing pen that uses recycled household plastic waste for filament can redefine 3D printing pens in the future. A Kickstarter project as of now, Renegade claims to be ‘reliable’ and that it recycles plastic bottles, files and bags.

Creator Daniel Edwards remarked, “We often use 3D printing for our projects, so we were regularly exposed to the price of standardized filaments. 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!” He was also reminded of “the mountains of used plastic bottles and bags that continue to critically pollute our environment.”

To recycle plastic bottles into filament needed by the pen, Renegade uses a ChupaCut, a device that acts as shredder to transform the bottles into plastic strips of 3, 6, 9, or 12mm thickness. ChupaCut also features curved blades so as to reduce friction and thereby offer faster, stable cutting and greater life. The device can hold larger bottles with stability and Renegade claims the ChupaCut can be used for many DIY projects too. A stand provided by Renegade can hold the pen and additional supplies. The stand is not very bulky and will take only little space of your desk. ChupaCut costs an additional £20 and the stand £12.

Renegade claims that “two 1.5L bottles or 12 plastic bags can replace 25 standard filaments and [thereby] save $10 to $15 each time.” Renegade- Reclaim, save and create aims to reduce plastic waste by recycling it in maximum ways possible, with 3D printing pens being one.On stretching and expansion of the project, Edwards added, “The mechanisms used in the pen are scalable, so one of our future goals is to design and develop a full-sized 3D printer that also operates on plastic waste. Implementing this would expand the user base, bringing affordable 3D printing to more places than ever before. It would also allow us to tackle the problem of pollution in a fun and inventive way — creating an incentive for the collection of plastic bottles, bags, and more from local communities throughout the world.”
