Printing Tips for Best Results

For optimal performance with this TPU filament, use a nozzle temperature of 220–240°C and a bed temperature of 30–60°C. Reduce your print speed to 20–40mm/s for cleaner, more accurate prints. A direct-drive extruder is highly recommended for the smoothest results with flexible filaments.

Frequently Asked Questions

Q: What is 95A Shore hardness and what does it mean for my TPU filament prints?

A: Shore hardness measures how stiff or flexible a material is. A 95A rating means this TPU filament is moderately flexible — soft enough to bend and stretch without cracking, yet firm enough to hold its shape under normal use. It's the sweet spot for functional parts like phone cases, grips, and wearable accessories.

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

A: Yes! DINGSUN 3D TPU Filament is designed to be compatible with most FDM (Fused Deposition Modeling) 3D printers that use a 1.75mm filament diameter. For best results with flexible TPU, a direct-drive extruder is recommended. Bowden-style setups can also work, but may require slower print speeds and fine-tuning.

Q: How should I store my TPU filament to keep it in good condition?

A: TPU is hygroscopic, meaning it can absorb moisture from the air over time, which can lead to bubbling, stringing, or poor layer adhesion during printing. Store your spool in an airtight container or resealable bag with silica gel desiccant packets. Keep it in a cool, dry place away from direct sunlight. Properly stored, the filament has a shelf life of 1 year.

Q: What spool size should I choose — 250g, 500g, or 1kg?

A: It depends on your project scope. The 250g spool is great for trying out the filament or small print jobs. The 500g spool suits medium projects or occasional users. The 1kg spool offers the best value for regular makers, large prints, or those who want a steady supply for multiple projects.
