This is our newest airless basketball filament made specifically for use with the BIQU PLA-HR filament: (https://shareasale.com/r.cfm?b=1890927&u=4425865&m=118144&urllink=&afftrack= ). With the right print settings, this basketball should meet the NBA regulations and requirements for size and weight. Watch our 3D printing video here: 

I have been testing many different filaments to see which ones make the best airless basketballs. You can follow our most up-to-date testing on our YouTube channel here: https://www.youtube.com/@makeitlabchannel. 

For this filament, I highly recommend a filament dryer (I use this one: https://youtu.be/L7AP0ahJMyo) and a printer bed glue stick for both bed adhesion and as a release agent when the basketball is done printing: https://amzn.to/3ALWcxK.
