DURAMIC 3D TPU Filament 1.75mm 2-Pack - Flexible, Durable Spool

In this review of the DURAMIC 3D TPU Filament 1.75mm 2-Pack the bottom line is simple: this filament is for makers and small workshops that need a reliable, rubber-like flexible material with tight diameter control. The reviewer found it especially useful for functional parts, jigs and flexible prototypes because of its high elasticity and a reported shore hardness around 95A, while the consistent diameter and jam-free production method delivered mostly clog-free printing across both direct and bowden extruders.

Key Features

• High Elasticity: The filament stretches up to three times its length, letting users print flexible, rubber-like parts that recover shape after deformation.
• Strong Shore Hardness: With a shore hardness of about 95A, printed parts resist abrasion and hold up well in functional use.
• Consistent Diameter: Digital caliper monitoring keeps diameter close to 1.75mm with tight tolerances to reduce feeding issues and improve dimensional reliability.
• Smooth, Stable Printing: The jam-free manufacturing claim and good layer adhesion gave smooth extrusion and fewer clogs in test prints at recommended settings.
• Two-Spool Value Pack: The 2 x 1kg spools include resealable aluminum bags and desiccant for better storage of unfinished spools.
• Printer Compatibility: Works with both direct drive and bowden printers and is usable in many 3D pens, expanding where it can be applied.

Who It's For

This filament is best for hobbyists, small shops, and engineers who need a flexible yet durable material for parts, grips, gaskets or low-load mechanical components. Its consistent diameter and user-friendly spool features suit people who print frequently and want predictable, clog-free extrusion.

Those who should look elsewhere include users needing ultra-soft TPU for wearable comfort or manufacturers requiring specialized chemical resistance beyond general TPU properties. Also, beginners completely new to flexible filaments may need some tuning to avoid feeder or adhesion quirks noted by a subset of users.

Pros & Cons

Pros

• Reliable elasticity and toughness make durable, flexible parts for functional use.
• Tight diameter control reduces filament diameter-related print failures and improves dimensional accuracy.
• Included storage bags with desiccant and spool features help prevent tangles and moisture issues between uses.
• Compatible with both direct and bowden systems, expanding printer compatibility.

Cons

• Some users report mixed adhesion behavior and occasional contact with feeder gears on certain setups, so tuning may be required.
• Depending on part thickness, the material can feel stiff rather than very soft for wearable applications.
