There are several 3D printing pens that use plastic filaments to create 3D structures that you can actually hold in your hands, one of them being the 3Doodler that we spent time with back in January 2015. What they all had in common was that the Filaments used tended to be expensive. That has changed with a new 3D pen that’s on Kickstarter now called Renegade. This pen can print using those regular filaments, but the really cool part is that it allows you to use plastic from old bottles or bags to build your artistic creations.
The Renegade ballpoint pen has a screw feed mechanism and heating system. This allows the boom to transport, destroy and melt the plastic tape produced by the ChupaCut plastic bottle crusher. That rotating screw head pushes the plastic forward evenly and extrudes the molten plastic from the nozzle. The plastic cools quickly giving it a stable 3D structure.
The manufacturer says that the device “has practically no material limitations.” The pen is designed to use 5 to 7mm strips cut from PET plastic bottles, plastic bags or plastic files with thicknesses ranging from 0.14 to 0.35mm. You can also use PLA, ABS, nylon, TPE, HIPS, wood and other standard filaments with a diameter of 1.75mm.
The Renegade ballpoint pen comes in matte black or matte white and has a removable attachment and ribbon spool. The ChupaCut can create 3, 6, 9 or 12mm plastic tapes. The Renegade pen is on Kickstarter fetching a little over $32,000 and has raised over $38,000 at the time of writing. The Renegade pen and spool retail for around $78. If you want the pen along with a ChupaCut bottle crusher, you need to spend around $118. A set with the pen, cutter, and fancy stand retails for $131. Shipping is estimated or January.
