Blue PLA-HR 1.75mm Flexible Filament 1KG Spool - Airless Basketball

In this review the reviewer examines the blue BIQU PLA-HR 1.75mm 1KG spool aimed at hobbyists and makers who want to print a playable airless basketball. The bottom line: this filament is compelling for users who want a filament tuned to deliver an authentic bounce and regulation-like weight when printed with the provided 3mf settings, but it may raise durability concerns for heavy long-term play. The review covers print setup, compatibility, feel, and real-world wear based strictly on the product details and customer feedback.

Key Features

• Predefined print profile: The included 3mf file supplies recommended settings so users can reproduce the intended structure and bounce without extensive tuning.
• Ball performance: When printed using the suggested settings the airless basketball achieves about 605g to 610g and returns impact energy for a natural bounce similar to a regulation ball.
• Flexi tough material: The filament is engineered to be resilient so the printed ball absorbs and returns impact energy while remaining flexible during play.
• Precision diameter: A tight tolerance of +/- 0.03mm improves feeding reliability across common 1.75mm FDM printers, reducing extrusion variation.
• Wide compatibility: Works with many popular FDM models such as Bambu-Lab, Ender-3 series, K1 Max, CR10, and BIQU printers when standard 1.75mm is supported.
• Manufacturer support: Products are manually inspected and the vendor offers technical help with promise to respond for quality issues within 24 hours.

Who It's For

This filament is best for 3D printer owners who want to produce a single-piece airless basketball that mimics the feel and flight of a traditional ball, especially those using printers known for reliability and who will use the provided 3mf file to avoid complex manual tuning. It also suits makers who value color fidelity and consistent filament diameter for repeatable prints.

It is less ideal for users seeking a long-term, heavy-duty sports ball without maintenance: some customers reported cracking after a few weeks of heavy use, so teams or frequent outdoor players should consider reinforced designs or alternate materials for rigorous play.

Pros & Cons

Pros

• Prints reliably when using the supplied 3mf profile, producing the intended bounce and weight.
• Color and filament quality earn positive feedback for clean, consistent extrusion.
• Broad printer compatibility thanks to tight diameter tolerance and standard 1.75mm sizing.
• Manufacturer offers accessible technical support and inspects products before shipping.

Cons

• Some users reported durability issues such as cracking after weeks of play, indicating potential limits for very aggressive use.
• Tangle resistance feedback is mixed and occasional surface imperfections were noted by some customers.

Our Verdict

The blue PLA-HR 1.75mm spool is a practical choice for makers who want to print a playable airless basketball with close-to-regulation weight and bounce when using the supplied 3mf profile.

Overall it represents good value for hobby use and controlled play.

Frequently Asked Questions

Do I need the 3mf file to get the proper ball performance?
Using the provided 3mf file is strongly recommended because it contains predefined settings that produce the intended bounce and weight.

Will this filament work with my Ender or Bambu-Lab printer?
Yes, the filament is compatible with a wide range of 1.75mm FDM printers including Ender series and Bambu-Lab models thanks to its tight diameter tolerance.

Is the printed ball durable for heavy outdoor play?
The material is designed to be resilient, but some customers reported cracking after weeks of aggressive use, so it may not suit constant heavy outdoor play without design reinforcement.
