NinjaFlex TPU 3D Printing Filament - 3mm .75kg - MUSTARD

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.

OK, I have to give this 5 stars but it's not perfect. But, the give and takes are a balance. This is an 'Expert' material for a reason. 3D printing the softest rubber is an amazing feat on a consumer-level machine (I'm on a Taz 6 with the Flexystruder v2 head). Any softer and you need to print molds and pour.This material has to print slow and you have to design your print carefully. You aren't going to get amazing detail with it, but it is quite cool and fun. Doesn't smell much, and $45 for a spool of this is good value. You might need a new head by the time you go through all this. ;') My head's gears are already showing wear after a few dozen hours of printing.

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
