It also comes with an in-built online slicer that you can use to slice your 3D models and generate the G-code to send to your 3D printer.

Build Responsibly With Recycled Filaments

These 3D printing filaments made from recycled materials are great because they are both eco-friendly and effective in the classroom. They help keep plastic out of landfills and cut down on demand for virgin materials by recycling post-consumer plastics and other forms of production waste. The smooth feeds, low warping, and minimal odor they provide are perfect for shared learning areas, and they keep up the print quality, consistency, and user-friendliness that students require for their projects. 

The fact that they are available in both PLA and PETG allows teachers a lot of leeway to create everything from delicate, colorful models to robust, practical components. Using these filaments demonstrates to students that environmentally conscientious decisions do not compromise the quality of their engineering, art, or STEM projects, and so enables schools to teach sustainability in a practical way.
