BIQU PLA-HR Flexible 1.75mm Filament 1KG Spool - Orange

In this review of the BIQU PLA-HR flexible filament, the bottom line is simple: this spool is aimed at makers who want a ready-to-print filament for producing airless basketballs and similarly resilient parts. Our review finds it most compelling for users willing to follow the provided 3mf profile or to copy the recommended settings, because those presets deliver the closest match to a regulation feel. The filament's color and print quality stand out, and when printed with the right parameters the airless basketballs show notable bounce and weight comparable to a standard ball.

Key Features

• Predefined 3mf profile: The included 3mf file supplies tuned settings so users can reproduce the intended ball performance without guesswork.
• Designed for airless basketballs: When printed with recommended settings the finished ball weighs about 605g-610g and returns a natural bounce similar to a regulation ball.
• Flexi tough material: The PLA-HR formulation claims high resilience to absorb and return impact energy for realistic play response.
• Wide printer compatibility: Tight diameter tolerance of +/- 0.03mm ensures reliable feeding across common 1.75mm FDM printers from hobby to prosumer models.
• Technical support and inspection: Each spool is manually inspected and the vendor offers a 24-hour response window for product quality concerns.
• Vibrant orange color: The spool prints a consistent, saturated orange that users noted as a positive visual trait.

Who It's For

This filament is best for hobbyists and small workshop users who want to 3D print functional sports gear, especially airless basketballs, and who will use the supplied 3mf file or carefully copy the recommended print settings. It's also suitable for owners of Bambu-Lab, Ender, CR series, and similar FDM machines because the spool is manufactured to a narrow tolerance.

Those who should look elsewhere include users needing a filament proven for long-term outdoor exposure or extreme impact conditions, and buyers who expect guaranteed multi-year crack resistance without testing. Some customers reported cracking over weeks, so professionals seeking guaranteed durability for heavy commercial use may prefer other elastomeric materials.

Pros & Cons

Pros

• Prints with good surface quality and consistent color when settings are followed.
• Makes an airless basketball that closely matches weight and bounce of a regulation ball using the recommended profile.
• Compatible with a wide range of 1.75mm FDM printers thanks to tight diameter tolerance.
• Vendor inspection and responsive technical support add confidence after purchase.

Cons

• Some users reported cracking of printed parts after a few weeks, indicating potential long-term durability limits.
• Tangle resistance feedback was mixed, with occasional bumps or feed issues reported by customers.

Our Verdict

The BIQU PLA-HR 1.75mm 1KG spool is a solid option for makers focused on printing airless basketballs who will use the provided 3mf settings; it delivers good print quality, accurate color, and a realistic bounce when printed correctly. However, buyers should be aware of reported cracking in some prints and mixed feed behavior, so it is best suited for experimental builds and enthusiasts rather than guaranteed long-term commercial use.
