NinjaTek - 3DNF0317505 3DNF03117505 NinjaFlex TPU Filament, 1.75mm, TPE.5kg, Fire (Red) (Pack of 1)

It's flexible and I've printed several things with it. I just find it more stringy than the black colored version.

The material is great super rubbery great for toys. Getting it to push threw a bowden tube though without bunching up is another challenge. Recommend direct drive though even then I had to do the ptfe tube wedge to keep it from bunching up. Once I wrangled it into the hotend though stuff was really great.

This stuff prints like a dream. Had a bit of trouble reducing stringing because I'm using a Bowden tube setup but seem to have got even that 99% handled. Picture is of my second draft printed next to another object. Takes patience and trial and error to learn how to print successfully but completely worth it.

Normally when I get filliment it's vacume sealed in a bag, this product was not and had to be baked for a couple hours before any really good prints could be made.

Flexibility, quality

Horrible quality control. I have gone through over a third of this 0.5kg roll and have had nothing but inconsistent extrusion on almost every print. Kept thinking I was having printer issues. Found my culprit was crazy inconsistent filament diameter. Unbelievable that this wasn't caught before packaging. Not to mention the cost of this stuff and that it comes packaged in a box with the tiniest decant pack ever made. REALLY disappointed with this product. Waiting to hear back from the manufacturer since I didn’t catch this issue until after my return window was closed.

No re-sealable bag, in fact no bag at all!!! TPU/TPE is hydroscopic, and this stuff came wet wet wet!!! Could not get to print consistently with good flow, and dryed in a dehydrator for 8 hrs. No master roll so realistically only first couple layers dried at all... Not like it’s the cheapest stuff either.....

I dialed this in for my 0.8mm nozzle and it printed great. (printing mostly Gaskets)I did dry this in my COSORI Premium Food Dehydrator Machine before I even printed because it shipped without a bag to seal it. (This is how NinjaTek ships this)
