Ultra-Flexible Performance with Enhanced Control

The Midnight Black NinjaTek NinjaFlex Edge TPE 83A filament is engineered for users who demand extreme flexibility without sacrificing print control. Developed by NinjaTek, this advanced TPE material builds on the trusted NinjaFlex platform by offering improved stiffness for easier handling while maintaining exceptional elasticity.

With a Shore hardness of 83A, NinjaFlex Edge is significantly softer than standard TPU, making it ideal for applications that require stretch, compression, and repeated movement.

Key Features & Benefits

• High Flexibility (83A Shore Hardness)
  Extremely flexible material ideal for soft-touch and compressible parts.
• Improved Print Control vs Traditional TPE
  Engineered to reduce buckling and feeding issues common with very soft filaments.
• Smooth, Matte Black Finish
  Produces clean, professional-looking prints with a consistent surface texture.
• Excellent Layer Adhesion
  Strong interlayer bonding ensures durability even under repeated flexing.
• Abrasion and Impact Resistance
  Designed for long-lasting parts that endure wear and mechanical stress.
• Reduced Stringing Compared to Softer TPEs
  Optimized formulation improves print quality and reduces post-processing.

Typical Applications

NinjaFlex Edge TPE 83A is ideal for highly flexible and functional designs:

• Wearables and soft-touch products
• Phone cases and protective covers
• Gaskets, seals, and flexible joints
• Vibration dampeners and shock absorbers
• Robotics components and soft mechanisms
• Medical and ergonomic prototypes (non-certified use)

Material & Compatibility

This 1.75mm filament is compatible with most FDM/FFF 3D printers capable of handling flexible materials.

Best Results With:

• Direct drive extruders (strongly recommended)
• Well-tuned Bowden systems (slower speeds required)

Printing Considerations:

• Slower print speeds compared to TPU for optimal control
• Consistent extrusion temperature for stable flow
• Heated bed recommended for improved adhesion
• Works well with PEI, glass, and textured build surfaces

Due to its softness, careful tuning of retraction and feed rates is important to achieve optimal results.

Why Users Choose NinjaFlex Edge

NinjaFlex Edge is designed for users who need maximum flexibility without the frustration often associated with soft filaments. It provides a more controlled printing experience while delivering the elastic performance expected from high-quality TPE.

Users rely on it for:

• Superior elasticity and compression resistance
• Better handling than traditional ultra-soft filaments
• Reliable print outcomes with proper setup
• Consistent quality across functional and aesthetic parts
