Airless Basketball Model - SainSmart PEBA

Edit: Added the 3mf file/profile on 5/8/2026 for printing the Siraya Tech PEBA with this model. The only difference is a nozzle temperature of 245C, and a Z-distance of 0.35mm. It uses the same model as the SainSmart PEBA.

I can't seem to add a printing profile because I had to create a profile with custom filament, so the 3MF is available for download instead. I will work on uploading a printing profile. 

This is our new SainSmart PEBA Airless Basketball model! The SainSmart PEBA is an incredible filament. This filament has had the best bounce/durability per cost that I have tested so far. At $60 or less per kilogram, it is the same price as the BIQUE PLA-HR filament, but has the same bounce/durability as the Kimya PEBA-S filament. Like all of the airless basketball filaments, I always dry the filament for several hours before printing, and I always add a release agent to the printing bed (glue stick) before printing.

I have included the STL for just the file, along with the 3MF that includes the settings and supports that I used to print the basketball. If you have any questions please feel free to reach out, and thank you for the support!
