Gembird's company motto "Shaping the perfection" alone shows that they pride themselves on the top quality of their products, and Gembird filaments are no exception. They don't release dangerous odors during printing and are made to avoid getting stuck in 3D printers. Filament FLEX indicates by its name that its material is flexible. They are made of thermoplastic elastomers, soft rubber materials and other additives. Thanks to its flexibility, you can use Gembird FLEX filament to print products that may be subject to impact, such as mobile device cases, car tyres for handling or even shoe parts.
