Compatible Printers

Works with most FDM (Fused Deposition Modeling) 3D printers that support 1.75mm filament, including popular models from Creality, Ender, Prusa, Anycubic, Bambu Lab, and more. For best results, use a direct-drive extruder setup when printing flexible TPU filament.

Frequently Asked Questions

Q: What type of 3D printers is this 1.75mm TPU filament compatible with?

A: This 1.75mm TPU filament is compatible with the vast majority of FDM 3D printers that accept 1.75mm diameter filament. It works with brands like Creality, Ender, Prusa, Anycubic, Bambu Lab, and many others. For the smoothest results with flexible TPU, a direct-drive extruder is highly recommended over a Bowden-style setup, as it provides better control over flexible material feeding.

Q: What does 95A Shore hardness mean for TPU filament?

A: Shore hardness is a measure of a material's resistance to permanent indentation. A 95A rating means this TPU filament is moderately flexible — softer and more rubber-like than rigid plastics like PLA or ABS, yet firm enough to hold its shape under normal use. It's ideal for applications requiring flexibility, impact resistance, and durability, such as phone cases, wearables, and gaskets.

Q: How do I prevent clogging when printing with TPU filament?

A: DINGSUN 3D's non-clogging formula significantly reduces the risk of nozzle blockages. For best results, print at slower speeds (15–30 mm/s is recommended for TPU), ensure your print temperature is within the filament's recommended range (typically 220–240°C), and keep retraction settings low or disabled. Store unused filament in a sealed, dry environment to prevent moisture absorption, which can also cause clogging.

Q: Is the transparent TPU filament truly clear after printing?

A: Yes! The Transparent Series TPU filament produces prints with a clear, see-through appearance. The level of transparency can vary slightly depending on your layer height, print speed, and temperature settings — thinner layers and slower speeds generally yield the clearest results. It's perfect for artistic displays, light-diffusing parts, and any project where visual clarity adds value.

Q: What is the diameter tolerance of this TPU filament, and why does it matter?

A: This filament maintains a tight ±0.03mm diameter tolerance, meaning the filament is extremely consistent in thickness throughout the entire spool. This precision is critical for smooth, uninterrupted extrusion — inconsistent diameter causes under-extrusion, over-extrusion, or clogs. With ±0.03mm accuracy, you get reliable, high-quality prints with excellent surface finish and detail.
