It's a Bowden style extruder, so I had to print a spacer to fit ahead of the PTFE tube so the filament will extrude without looping onto itself. It really is the consistency of something like al dente cooked spaghetti.Initially I was able to print at 210C with a 40C heated bed. The next time I tried, it didn't want to extrude at that temperature so I upped it to 220C with a 40C bed. At 10mm/sec, it prints quite well. Slow, but pretty well. Also go slowly when preheating the hot end... the filament will "drool" for a bit as it's primed into the system. It takes a bit to get the right settings dialed in, but when they are, it prints fairly well.I did have overhand on my part, and therefore needed to have a raft and supports. Some configurations work better than others; you'll have to experiment and learn what works and what doesn't. PLA it's not! That said, one can achieve different "effective" Shore A durometers from this material depending on the size of the part being printed, the thickness of the shell, and the infill density. Experiment - I got the exact same part to feel like about 30 Shore A and another to feel like about 70 Shore A, just by changing the shell and infill percentage.Overall, so far.. good stuff. Wish it was a bit easier to get extruded and started printing, but in general I'm satisfied. ### ⭐⭐⭐⭐ Unravel enough length from the spool and omit the filament feed tube -- prints very well! *by A***R on Reviewed in the United States on June 24, 2017* This is fun stuff! Use 100% infill for gaskets and watch straps, but drop the infill to 10% for a spongy pillow-like effect on large cavities. Seems durable.The biggest problem was getting it to feed reliably. The trick is to use a direct extruder (e.g. FlashForge Creator Pro) and NOT to use the spool or the plastic filament feed tube. This filament is gummy-ish and does NOT pull off the spool easily nor feed through the tube down into the extruder very well. I was always getting underflow/no_flow issues because the extruder gear just can't bite into it well enough to keep it moving.The slicer should tell you how many meters of filament will be required. Unroll a little more than that and let it dangle directly out of the extruder inlet and off the side of the machine in a fashion that won't tangle on the floor. Drop your print speeds and be patient. Be aware that it dribbles a lot as it's preheating. Keep the extruder off to the side so it won't drip on your print area and do one last snip/wipe right before it starts to print, to remove the last snot glob. It should reward you with a great print. ### ⭐ Horrible Filliment *by A***R on Reviewed in the United States on December 9, 2018* I tinkered with getting this to print for weeks. I tried lots of Temps, Speeds, cleaning and replacing the PFTE Tube in the extruder. constantly had issues. Several times had great starts only to come back later to a half printed object.The spool was not wound very tight and not consistent, so I unwound 50ft of it (Enough to print my object) and found it on a separate roll. It had kinks in the filament every 10-15ft that were jamming the extruder!Quality control was clearly asleep on the job on this roll. Who knows how many more are like this. I would not recommend. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/170936132-ninjaflex-tpu-3d-printing-filament-3mm-75kg-caramel](https://www.desertcart.hr/products/170936132-ninjaflex-tpu-3d-printing-filament-3mm-75kg-caramel) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
