The FLEX 45 is available in 5 colours. Samples of 50gr. are available (in white only). Make your choice!

Flex 45 is a highly flexible rubber replacement filament for 3D printing. The combination of flexibility, mechanical strength, durability (in the service life) and good resistance to chemicals as well as extreme temperatures makes it a unique filament. This bio-performance thermoplastic co-polyester has a high carbon content in renewable materials, which reduces the environmental impact. Finally, the FLEX 45 has excellent UV resistance.

Directions for use:
– The recommended temperature for the heating mat is ± 100°C. Various other options are possible (without heating mat, warmer, less hot, etc.) depending on the type and size of the object to be printed. We recommend using a hook like the EZ Stick (for any type of parts), an adhesive such as Kapton (for small parts), glue (for large parts), or even both (Kapton and glue). If you use glue, no need to put it on the entire surface of the part, but only on the contours or areas at risk of retraction.
– The FLEX 45 prints better at a slower speed, due to its flexibility.
– The FLEX 45 is preferably used on 3D printers with direct filament deposition.

Storage tips:
– Our filaments are filmed, in a cardboard box without window filmed also to ensure the good conservation of the product until the moment of use.
– Store it in a cold and dry environment (15 – 25 ° C), away from light (UV) and under vacuum (to stay dry). We recommend that, after each use, you vacuum it by slipping a silica gel pouch into it and in its box protected from UV. Good storage significantly increases the shelf life of your filament.
