• Spool Weight: 0.25kg

Compatible with most FDM/FFF 3D printers that support flexible filaments:

• Direct drive extruders recommended for best results
• Bowden setups can be used with reduced speeds and tuning
• Heated bed improves adhesion and consistency
• Works well on PEI, textured build plates, or glass with adhesive

Printability & Performance

• Ease of Printing: Moderate and user-friendly for TPU
• Surface Finish: Smooth with a slightly satin flexible texture
• Flexibility: High with excellent recovery after bending
• Bed Adhesion: Strong with proper setup
• Warping: Minimal
• Stringing: Lower than softer TPU grades

Glow additives may slightly increase wear on nozzles over time, so hardened nozzles are recommended for extended use.
