Frequently Asked Questions

Q: What is 95A Shore hardness TPU filament and how flexible is it?

A: Shore 95A is a soft-to-medium flexibility rating for TPU filament. It means the filament — and finished prints — can bend, compress, and flex significantly without cracking or breaking, making it ideal for phone cases, gaskets, wearables, and grip components. It is softer than rigid PLA or ABS but holds its structure well under repeated stress.

Q: What print settings are recommended for this 1.75mm TPU filament?

A: For best results with DINGSUN 3D 95A TPU filament, use a nozzle temperature of approximately 220–240°C, a bed temperature of 30–60°C, and a print speed suited to your printer's direct-drive or Bowden extruder setup. Direct-drive extruders typically handle TPU more reliably. Slow down retraction settings to prevent jamming and enable a smooth, consistent extrusion.

Q: How does the luminous glow effect work?

A: The luminous TPU filament contains phosphorescent pigments that absorb ambient or UV light and re-emit it as a visible glow in low-light or dark conditions. Simply expose your finished print to light for a short period, then move it to a dark environment to see the glow effect. The brightness and duration of glow depend on the intensity and duration of light exposure.

Q: Is this filament compatible with my FDM 3D printer?

A: Yes — the 1.75mm diameter is compatible with the vast majority of consumer and prosumer FDM 3D printers, including popular models from Creality, Bambu Lab, Prusa, Anycubic, and more. Always verify your printer's nozzle diameter and extruder type before printing flexible filaments.
