NinjaFlex Filaments

Colors, Diameters and Shore Hardness

We carry a wide range of ninjaflex filaments in the Adafruit shop. We carry several colors, filament diameters and types (Cheetah and regular Minjaflex). You can see all them by clicking on the shop category link below.

What Is Shore Hardness?

The different types of Ninjaflex list Shore Hardness as a way to reference how hard the material is. It's basically a unit of measurement for hardness. The lower the value, the "softer" it is.

Regular Ninjaflex has a rating of 85A, while Cheetah Ninjaflex is rated at 95A.

From Wikipedia

The durometer scale was defined by Albert FerdinandShore, who developed a device to measure Shore hardness in the 1920s. The term durometer is often used to refer to the measurement as well as the instrument itself. Durometer is typically used as a measure of hardness in polymers, elastomers, and rubbers.

Painting on Ninjaflex

We've found it is possible to air bush on the surface of 3D printed Ninjaflex parts. It's not prone to bleeding, so you can achieve details to create intricate shapes and patterns.

NinjaFlex vs SemiFlex

The newest addition to the NinjaFlex family, SemiFlex 3D Filament is now available! Just like the original NinjaFlex 3D Filament, SemiFlex material boasts flexibility, strength and reliability for your 3D printing projects, and is slightly more rigid to expand your printing possibilities.

SemiFlex is best for the following types of projects:

  • High level of detail
  • Contain intricate parts
  • High resolution text
  • Unsupported vertical printing
  • Shock-absorption needed
  • Requires less flexibility than NinjaFlex Original 3D Filament

NinjaFlex is best suited for:

  • Fused Deposition 3D printers that use 1.75mm or 3mm filament
  • 3D printers that accept other types of filaments such as ABS and PLA
