The new Renegade 3D pen was born with the aim of being the perfect solid tool to eliminate overpriced 3D printing filaments and to save the environment by directly recycling and reusing household plastic waste for 3D printing.
The sustainable technology specializes in one thing, and one thing only — it prints models by recycling plastic bottles, files, and bags. It does this providing a great 3D printing experience with no compromises.
The pen uses a robust and powerful extruder that includes a screw-feeder mechanism and heating system. These combine to transport, destruct, and melt the plastic tape produced by the ‘chupacut’ plastic bottle shredder or even standard filaments.
The rotating screw forces the heated plastic to move forward evenly and extrudes it from the nozzle. The molten plastic then cools down rapidly into a solid and stable spatial structure. The tool uses a powerful drive motor and gearbox, eliminating well-known issues in plastic material feeding that most 3D pens currently face.
The temperature is adjustable from 50°C to 320°C using a single controller and the speed is also controlled by a single button.
The sustainable instrument can use 5 to 7 mm strips cut from PET plastic bottles, plastic bags, or plastic files with a thickness of 0.14 to 0.35mm. It can also use standard PLA, ABS, nylon, TPE, HIPS, wood and other types of filament with a diameter of 1.75 mm. It is available in two finish options: matte black and matte white plus features a removable attachment with a colourful spool for plastic tapes.
Chupacut is a manual plastic bottle shredder which produces the perfect plastic strips to use with the 3d printing pen. Its spherical shape allows it to create 3, 6, 9, or 12mm plastic strips without ever having to change the setup.
It has curved slots that significantly reduce friction force and provide a very efficient rotation of the bottle, keeping it at an acute angle with the blade as it’s being cut. This also prolongs the lifespan of the blade, and results in a faster, more stable cutting process.
The design ensures that the blade is completely enclosed within the instrument. After installation, the blade can only be removed by using another similar-sized blade for safety purposes. Chupacut’s telescopic holder keeps large bottles stable – in any position. A stable bottle means a more reliable cutting process that yields the smoothest plastic strips.
