Formfutura 1.75mm Crystal Flex – Clear – 3D Printer Filament

Crystal Flex is a heavy duty, translucent and yet flexible filament. Crystal Flex’s transparency is being described as “plexiglass-like” as apparently Crystal Flex will let 91% of visible light pass through its fibre. Crystal Flex is as clear as Polycarbonate filament. This unique feature makes Crystal Flex extremely suitable for printing light-transmitting objects. Another great feature about Crystal Flex is its resilience and bendability. Crystal Flex is a very tough material and has a shore hardness of D65, which enables this filament to being bent up to 175% without causing white stress marks after bending. Crystal Flex has a high interlayer adhesion, making it a really wonderful and easy-to-print filament. Crystal Flex’s recommended printing temperature is between 230° and 260°C, with 260°C as recommended temperature for best layer adhesion during printing at high speed. Crystal Flex’s thermal stability is comparable with that of PLA (65° – 70°C). Crystal Flex’s water absorption is only 30% of that of ABS, meaning that there will be less evaporation and therefore prints are less likely to warp. Crystal Flex sticks well to ABS and PLA, which makes this 3D printer filament also suitable for multi-material prints. However, do keep in mind that Crystal Flex gets crumbly from Acetone. So it is recommended not to smooth your ABS/Crystal Flex multi-material prints afterwards with Acetone. Crystal Flex’s unique set of characteristics with respect to its high impact resistance, light emission, and flexibility enables a whole new field of application for FFF/FDM desktop 3D printers. Crystal Flex’s bendability and high impact strength allow the material being used for instance for hinges and other mechanical parts to be built into other, firmer and inflexible parts. The combination of being flexible and resilient make Crystal Flex also very suitable for creating belts and straps.
