  Provides the perfect balance between softness and rigidity for functional applications
• Excellent Layer Adhesion
  Produces strong, durable parts with minimal risk of delamination
• Reliable Printability
  Easier to print than softer TPU grades, reducing jams and feeding issues
• High Abrasion & Impact Resistance
  Ideal for parts that experience repeated stress, bending, or wear
• Vibrant Lime Green Color
  Bright, consistent pigmentation for visually striking prints
• Reduced Stringing Behavior
  Engineered formulation helps improve print quality and surface finish

Typical Applications

Spectrum S-Flex 90A is widely used for both hobbyist and professional applications, including:

• Flexible hinges and joints
• Phone cases and protective covers
• Gaskets and seals
• Wearable components
• RC tires and shock-absorbing parts
• Tool grips and ergonomic handles
• Industrial prototyping requiring flexibility

Material & Compatibility

This TPU-based filament is compatible with most desktop FDM/FFF 3D printers that support flexible materials. For best results:

• Works well with both direct drive and optimized Bowden setups
• Performs best at moderate print speeds
• Compatible with common heated beds and standard build surfaces

Recommended Printing Considerations:

• Use slower print speeds for improved accuracy
• Ensure proper filament path tension
• Minimize retraction settings to reduce stringing
