Introducing more sustainable plastics is key to reduce waste and save natural resources. Real filaments' Recycled PETG 3D filament is produced from quality ensured waste supplies and checked for consistency during the entire production process, ensuring the best possible 3D printing experience while reusing at least 95% material. With our famous white recyclable cardboard spool, this product is a big step in using precious natural resources in a better way and part our our continued effort in making 3D printing an even more 'greener' alternative to traditional manufacturing methods. On the spool is 1 kg Gray filament in 1.75 mm diameter. Printing this filament requires a heated bed at about 65 degrees and less cooling than regular PETG. A 3d print at normal speeds prints best around 245 degrees, slower or faster printing speeds may need tweaking the temperature just slightly.
