Review on 🔩 3DNF14117505 NinjaTek NinjaFlex TPE Filament 5Kg by Abdullah Huan

This does NOT look like normal flexible TPU. It's MUCH more flexible. You MUST make sure your printer is set to print VERY flexible filament. I have two Bowden tube printers and I'm getting great results with a simple change in the extruder feed path. A piece of Bowden cable a few millimeters long with a V-notch at one end is sufficient. A small gap between the extruder drive and the Bowden cable leading to the printer remains to be eliminated. I just let the short tube hover over the drive wheel. I need to increase the feed rate to 1.2 and print SLOWLY. maybe 20mm/s. Good smooth results on bare glass as it sticks very well to a warm bed. I use temperatures between 50 and 65 degrees Celsius. My only complaint: very expensive for a 0.5kg roll. For some reason they use a LARGER spool than the standard 1kg spool. (Mostly empty and too big to fit in a 1 gallon ziplock bag. I've noticed that a couple of rolls I've received will never fit in a vacuum bag and print perfectly, so I'm guessing the humidity at this is not a factor... Prints Understand that this is NOT like normal TPU, it is a special filament for a very specific use.
