Sample Box 3 IMPORTANT - These filaments are extremely sensitive to moisture. If the filament is exposed to air for a long period of time during printing, there is a very high risk of decreasing the quality of the filament. It is therefore necessary to keep the filament in a dry storage box at all times, even during printing. This box helps to preserve the integrity of the filament and protect it so that it retains its unique properties. Since this product can degrade easily, it is essential to obtain a filament dehydrator and use it to dry the filament before using it. For the dry storage box, we recommend the Polymaker PolyBox Edition II. For a Filament dehydrator, we recommend the PrintDry Filament Dryer Pro. The Sample Box 1 contains 2x100g sample: Diameter: 1.75mm Color: Black CF and Grey GF PolyMide™ PA6-CF and PolyMide™ PA6-GF These samples require a 3D printer capable of reaching a nozzle temperature of 300˚C and equipped with an abrasion resistant nozzle.
