Frequently Asked Questions

Q: What printers are compatible with DINGSUN TPU 1.75mm filament?

A: DINGSUN TPU 1.75mm filament is compatible with most standard FDM 3D printers that accept a 1.75mm diameter filament, including popular models from Creality (Ender series), Prusa, Anycubic, Bambu Lab, and many others. We recommend using a direct-drive extruder for the best results with flexible TPU filament, though Bowden setups can also work with tuned retraction settings.

Q: What print temperature and settings are recommended for TPU 98A filament?

A: For optimal printing with DINGSUN TPU 98A filament, a nozzle temperature of 220–240°C and a bed temperature of 30–60°C are generally recommended. Print slowly (20–30 mm/s) to prevent filament buckling, especially in Bowden-style printers. Minimal or zero retraction is advised to reduce stringing and ensure smooth extrusion.

Q: How should I store TPU filament to preserve its shelf life?

A: TPU filament is hygroscopic, meaning it absorbs moisture from the air, which can lead to poor print quality (bubbling, stringing, or weak layers). Store your DINGSUN TPU filament in an airtight container or resealable bag with silica gel desiccant packets, away from direct sunlight and humidity. Proper storage helps maintain a shelf life of up to 1 year.

Q: What is the difference between 98A TPU and softer TPU filaments?

A: Shore hardness indicates flexibility — a 98A rating means the filament is on the firmer end of the flexible spectrum. It offers excellent elasticity and bend recovery while still being rigid enough for detailed, structural prints. Softer TPU (e.g., 87A or 95A) is more rubbery and pliable. 98A is ideal for functional parts that need both flexibility and structural integrity, such as phone cases, grips, and mechanical components.
