Cheetah
™
3D Printing Filament
Flexible Polyurethane Material for FDM Printers
Cheetah™ 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.

NinjaTek filament is capable of being printed by a variety of printers in a variety of configurations. This specification sheet gives results as they pertain to the defined test standard and specimen details. Different slicing and/or
printing configurations, test conditions, ambient environments, etc. may result in different results.
Impact Strength and Heat Deflection Temperature results were both provided by an accredited university testing laboratory. Specific Gravity and Hardness are innate characteristics of the material. Moisture Absorption, values
associated with the Tensile Strength tests, Melting Point and Glass Transition data were prepared by Fenner Drives, Inc.
NinjaTek makes no warranties of any type, express or implied, including, but no liited to, the warranties of fitness for a partuclar application.
