NinjaFlex TPU 3D Printing Filament - 3mm .75kg - RADIANT ORCHID

Better than I expected, but still has its drawbacks.First, I am using this on a Monoprice Mini Select V2 3D printer. 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.

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.

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.

This NinjaFlex is great. I had no issues printing with the NinjaFlex on the Flashforge Dreamer. I'm printing with Simplify3D, and I did need to create a custom NinjaFlex material profile. I did have to create an external spool holder (made mine out of 3/4" PVC), since this spool will not sit inside the FF Dreamer. I have not yet tried printing two NinjaFlex colors on one print.Add these configurations to your ".fff" configuration file and printing with NinjaFlex should work without much issue:<autoConfigureMaterial name="NinjaFlex"> <defaultSpeed>1200</defaultSpeed> <extruder name="Right Extruder"> <toolheadNumber>0</toolheadNumber> <diameter>0.4</diameter> <autoWidth>0</autoWidth> <width>0.4</width> <extrusionMultiplier>0.9</extrusionMultiplier> <useRetract>1</useRetract> <retractionDistance>1.5</retractionDistance> <extraRestartDistance>0</extraRestartDistance> <retractionZLift>0</retractionZLift> <retractionSpeed>1800</retractionSpeed> <useCoasting>0</useCoasting> <coastingDistance>0.2</coastingDistance> <useWipe>0</useWipe> <wipeDistance>5</wipeDistance> </extruder> <extruder name="Left Extruder"> <toolheadNumber>1</toolheadNumber> <diameter>0.4</diameter> <autoWidth>0</autoWidth> <width>0.4</width> <extrusionMultiplier>1</extrusionMultiplier> <useRetract>1</useRetract> <retractionDistance>1.5</retractionDistance> <extraRestartDistance>0</extraRestartDistance> <retractionZLift>0</retractionZLift> <retractionSpeed>1800</retractionSpeed> <useCoasting>0</useCoasting> <coastingDistance>0.2</coastingDistance> <useWipe>0</useWipe> <wipeDistance>5</wipeDistance> </extruder> <temperatureController name="Right Extruder"> <temperatureNumber>0</temperatureNumber> <isHeatedBed>0</isHeatedBed> <relayBetweenLayers>0</relayBetweenLayers> <relayBetweenLoops>0</relayBetweenLoops> <stabilizeAtStartup>0</stabilizeAtStartup> <setpoint layer="1" temperature="235"> </temperatureController> <temperatureController name="Left Extruder"> <temperatureNumber>1</temperatureNumber> <isHeatedBed>0</isHeatedBed> <relayBetweenLayers>0</relayBetweenLayers> <relayBetweenLoops>0</relayBetweenLoops> <stabilizeAtStartup>0</stabilizeAtStartup> <setpoint layer="1" temperature="235"> </temperatureController> <temperatureController name="Heated Build Platform"> <temperatureNumber>0</temperatureNumber> <isHeatedBed>1</isHeatedBed> <relayBetweenLayers>0</relayBetweenLayers> <relayBetweenLoops>0</relayBetweenLoops> <stabilizeAtStartup>0</stabilizeAtStartup> <setpoint layer="1" temperature="40"> </temperatureController> <fanSpeed> <setpoint layer="1" speed="0"> <setpoint layer="2" speed="100"> </fanSpeed> </autoConfigureMaterial>

This is awesome! Very temperamental, but once you get the hang of it, it's great. My husband made himself a wallet from it!

Very difficult to print with. Once you get the settings just right prints come out fantastic though. Used to print some Open-RC tyres.

flexible doesnt quite cover it. this stuff is almost like rubber

good quality, easy to print, fast seller

Come really quickly and a great product
