TPU Filament 1.75mm 1kg - Flexible, High Resilience TPU for 3D

In this review of Creality's CR-TPU filament, the bottom line is simple: this 1.75mm, 1kg spool is best for users who need flexible, durable prints with strong layer adhesion. The filament's high resilience and soft adhesive material make it well suited for functional parts like seals and phone cases, while its advertised 95A Shore hardness promises a rubberlike toughness. The following review evaluates print quality, compatibility, and real-world usability so makers can judge whether this TPU fits their workflow.

Key Features

• High resilience: The material returns to shape after deformation, making prints suitable for flexible, load-bearing applications such as seals and wearable parts.
• Good glossiness: Prints show a smooth, glossy surface that improves the aesthetic finish of flexible models without heavy post-processing.
• Strong interlayer bonding: The soft adhesive formulation promotes excellent layer adhesion for enhanced part stability and fewer delamination issues.
• Wear and aging resistance: Finished prints resist wear, scratches, and environmental aging, extending usable life for practical parts.
• Chemical and moisture resistance: The filament tolerates water, oils, and many solvents and is described as waterproof and moisture proof for tougher environments.
• Wide compatibility: CR-TPU is compatible with most FDM 3D printers that accept 1.75mm filament, making it easy to integrate into existing setups.

Who It's For

This TPU filament is aimed at hobbyists and professionals who print flexible parts that must withstand repeated deformation, such as rubber seals, shoe prototypes, and protective cases. Its combination of elasticity, gloss, and chemical resistance makes it a practical choice for wearable items and functional prototypes where toughness and finish matter.

It may be less appropriate for users who require ultra-soft elastomers below 95A Shore hardness or those using printers that struggle with flexible materials without a direct-drive or carefully tuned feeding system. Users seeking guaranteed consistency should note that customer reports vary on batch quality and rigidity.

Pros & Cons

Pros

• Elastic and resilient material that produces flexible, functional parts with good recovery.
• Glossy surface finish and strong interlayer adhesion give smoother, more durable prints.
• Good resistance to wear, UV, moisture, and many chemicals increases part longevity.
• Works with a wide range of FDM printers and is easy to work with when printer settings are tuned.

Cons

• Customer reports are mixed on filament consistency and functionality, so some batches may perform better than others.
• Parts can be perceived as rigid or brittle by some users depending on print settings and part geometry.

Frequently Asked Questions

Is this filament compatible with my FDM printer?
Yes, CR-TPU is 1.75mm and designed for broad FDM compatibility, but printers without a reliable flexible filament feed may require tuning or a direct-drive setup.

What parts are best to print with this TPU?
Its high resilience and chemical resistance make it good for seals, phone cases, shoe prototypes, and other parts that need flexibility and durability.

How should I store the filament?
Store in a dry, ventilated place away from high temperature, direct sun, and high humidity to preserve material properties.
