Kingroon TPU 3D Printer Filament 10 Rolls - Flexible, Accurate 1.75mm

In this review we look at the Kingroon TPU 3D Printer Filament 10 Rolls pack, aimed at makers and small workshops that need a lot of flexible material on hand. The bottom line: this set is best for users who value consistent diameter and ready-to-print spools for flexible parts; its dimensional accuracy and low-odor, low-warp profile make it an easy choice for repeated prints. The pack includes a wide color range and large total weight, so it suits batch work and prototyping where elasticity and bed adhesion matter.

Key Features

• Soft filament with high elasticity: The TPU formulation produces flexible parts that withstand bending and stretching without immediate deformation.
• Dimensional accuracy: The 1.75 mm diameter is manufactured to tight tolerances (noted as +/- 0.03 mm in the product name) to reduce nozzle clogs and maintain extrusion consistency.
• Ten-roll bulk pack: The 10-kg total (ten 1 kg spools) supply keeps printers running for multiple projects and reduces spool changes.
• Clog-free, bubble-free preparation: Spools are described as fully dried and free of air pockets to improve first-layer reliability and reduce print failures.
• Wide printer compatibility: The filament is compatible with common 1.75 mm FDM desktop printers, making it easy to switch from rigid materials to flexible TPU.

Who It's For

This pack is aimed at hobbyists, small business prototypers, and educators who print flexible components like gaskets, phone cases, wearable prototypes, or damping mounts. The large combined weight and variety of colors are practical for labs and makerspaces that need repeatable flexible prints without constant reordering.

Users who should look elsewhere include those who only need single small spools or strictly require engineered TPU grades with certified mechanical testing beyond the provided tolerance and printing guidance. If you need rigid PLA-specific characteristics, the TPU set will not deliver the same stiffness.

Pros & Cons

Pros

• Consistent 1.75 mm diameter reduces extrusion variance and helps avoid clogs during long print runs.
• Good bed adhesion and low-warp behavior make it reliable for flexible prints without complex bed preparations.
• The bulk 10-roll pack and multiple colors are cost-effective for repeated use and prototyping.
• Manufacturing steps such as complete drying help minimize bubbles and printing interruptions.

Cons

• TPU prints are inherently soft and not suitable where rigid strength or very high-temperature resistance is required.
• Bulk quantity may be excessive for casual users who prefer to trial a single spool before committing to a multi-roll pack.

Our Verdict

Its consistent diameter, low-warp printing and pre-dried spools lower the chance of print interruptions, making it good value for sustained prototyping and runs where elasticity matters.

Frequently Asked Questions

Is this filament compatible with my 1.75 mm FDM printer?
Yes. The filament is designed for common 1.75 mm FDM desktop printers and should work with most setups that handle TPU.

Do the spools require drying before use?
The product notes that spools are fully dried for 24 hours, so they are ready to print; if your environment is very humid, a brief drying cycle can help.

What printing temperatures are recommended?
While TPU specifics depend on the printer and part, the product notes general PLA and PETG ranges; for TPU, follow your printer and filament guidelines and start with a moderate nozzle temperature and slow print speed for best results.
