DURAMIC 3D TPU Filament 1.75mm Black White - Flexible 95A, 2 Pack

In this review of the DURAMIC 3D TPU filament 1.75mm, the bottom line is simple: this 2 pack is best for makers who need a durable, rubber-like filament that prints reliably with minimal fuss. The reviewer found the filament's combination of high elasticity and a firm 95A shore hardness makes it ideal for functional parts that must flex yet resist wear. With a focus on consistent diameter and jam-free formulation, this filament is designed to reduce clogs and deliver repeatable results for both hobbyists and light industrial use.

Key Features

• High elasticity: The filament stretches up to three times its length, allowing prints that need significant flex without tearing.
• 95A shore hardness: A firm, durable feel makes printed parts suitable for jigs, tools, and functional prototypes that face mechanical stress.
• Dimensional accuracy: Measured with a digital caliper system, the 1.75mm diameter maintains tight tolerances for clog-free extrusion.
• Smooth, stable printing: A jam-free patent and good layer adhesion produce consistent extrusion and fewer interruptions during multi-hour prints.
• Bowden and direct compatibility: Works with both direct drive and bowden printers plus 3D pens, expanding printer compatibility for a variety of setups.
• Practical packaging: Two 1kg spools arrive in resealable foil bags with desiccant and a storage hole on the spool to prevent tangles.

Who It's For

The DURAMIC TPU filament suits makers, small shops, and product developers who need a flexible filament with high tear resistance and consistent diameter for reliable prints. It is particularly useful for printing wearable prototypes, flexible enclosures, grips, and functional components that undergo bending or repeated motion.

Users who depend on ultra-soft rubber-like materials (much lower shore hardness) or who require extremely high-temperature performance should consider other elastomers. Also, beginners who cannot tune retraction and temperature may encounter occasional adhesion or stringing issues before dialing in settings.

Pros & Cons

Pros

• Consistent diameter control reduces the risk of clogging and improves first-layer reliability.
• Strong elasticity combined with a 95A hardness delivers robust, flexible parts for functional use.
• Jam-free formulation and good layer adhesion support smoother long prints and fewer failures.
• Two-spool kit and resealable packaging make storage and ongoing use convenient.

Cons

• Some users report mixed adhesion to feeder gears and variable stringing until print settings are tuned.
• The 95A hardness is firm; those seeking very soft elastomers may find it too stiff.

Our Verdict

The DURAMIC 3D TPU 1.75mm two-spool kit is a solid choice for makers who need a dependable, wear-resistant flexible filament that prints smoothly once tuned. Its tight diameter control and jam-free formulation provide good value for those producing functional parts and prototypes, though users should expect to adjust retraction and temperature to minimize stringing.

Frequently Asked Questions
