Each Splash Spool is loaded with approximately 50 grams of NinjaTek's CHEETAH 1.75MM TPU flexible filament (~57 feet/17.37 meters). CHEETAH is made in the USA. CheetahTM flexible filament is the fastest and easiest to print flexible filament on the market. The focus in development of this material was on optimizing the user experience. The result is a filament that is printable across all types of desktop 3D printers at ABS and PLA speeds, many times twice the speed of other flexible materials on the market.
