🔧 NinjaTek 3DNF03117505 NinjaFlex Filament TPE 5Kg: Flexible 3D Printing Filament for Versatile Projects Review

This stuff prints like a dream. I had a bit of trouble reducing the string tension due to using a bowden tube setup, but I seem to be 99% balanced with that. The image of my second draft is printed next to another object. It takes patience and trial and error to learn how to type successfully, but it's worth it.

Excellent material, super rubber, great for toys. Getting him to squeeze the Bowden tube while not crouched is another problem. Recommend direct drive, although even then I had to make a wedge out of teflon tubing to keep it from building up. I pushed it to the hot end once, even though everything was really great.

Terrible quality control. I used over a third of that 0.5kg roll and had nothing but intermittent extrusion on almost every print. The whole time I thought I had problems with the printer. I found the culprit in the crazy discrepancy between the diameter of the filament. It is unbelievable that it was not caught before packaging. Not to mention the cost of this stuff and the fact that it comes packaged in a box with the smallest bottle ever made. VERY disappointed in this product. I'm awaiting…
