BIQU PLA-HR Flexible 3D Printer Filament Specifically for Printing Airless Basketballs, 1.75mm 1KG Spool (2.2lbs), Flexi Tough Filament Compatible with Most FDM 3D Printer (Black)

Love this filament for TPU replacement. It is better in every way than the TPU that I have used in the past. It's very durable, is relatively hard yet flexible, but most importantly it can take a real beating and survive. I've printed tennis balls out of this and they just work. Tires, wiper, gaskets, all good options for this filament. I use a 0.6mm nozzle and as long as it's very dry, it prints easily.

Followed all of the manufacturer’s recommendations as far as settings. I calibrated and leveled my Bambu a1 right before print. Used their cryogrip build plate. I even printed a smaller 5” ball before the print of the bigger ball (with cracked also due to what I thought to be excessive use or scaling down the size caused weakness in the model. The big ball printed out, and the quality was decent. However, I dropped the ball from about 3 feet in the air ( waist high) and the ball shattered. I emailed the manufacturer and they would not replace the filament. I was very disappointed in the customer service and the fact that they are selling shotty materials and will not replace if you followed all the recommended steps. BUYER BEWARE!

Printed with a Bambulab X1C. Used .6mm nozzle and .3mf file supplied by Biqu. Print speed at 80mm/s and 230C. Thank God I used 3dLac spray on the smooth PEI bed. Otherwise, I would not have been able to remove the print without damaging the plate. This stuff sticks! Dried the heck out of the filament at 45C for 24 hours. Biqu says use 60 - 65C, but I don't trust that much heat for PLA. Print was a little rougher than I would hope due to .6mm nozzle and maybe the print speed. Printed without a hitch and bounces pretty well. My grandson absolutely loves it.

Good filament and prints well. Just a little way too pricy

I have been trying to print a basketball and haven't had a successful print yet. The print constantly warps and pulls free from the bed. I have an enclosed printer (X1 C) and have printed with Elmers, Bambu's glue, and without. The prints pull free from the plate every time. This has eaten two complete rolls of filament. This makes for an expensive fail.

Bought a basketball already printed from Biqu. It broke after 3 days of regular use. I have emailed the company and they will not respond.
