 | 

Color:MUSTARD




























NinjaFlex flexible filament leads the industry thanks to its superior flexibility and longevity compared to non-polyurethane materials. Its consistency in diameter and orality (roundness) outpaces other polyurethane materials. Made from a specially formulated thermoplastic polyurethane (TPU) material, this patented technology boasts a low-tack, easy-to-feed texture. The result is uniquely flexible, strong prints ideal for direct-drive extruders. Suggested Applications: Seals, gaskets, plugs, leveling feet, protective applications. KEY FEATURES: Polyurethane composition allows for excellent vibration reduction Patented low friction exterior allows for smooth feeding Consistent diameter and material properties providing reliable, high quality prints Chemical resistant to many materials, including naphtha, ASTM Oils #1-3, petroleum and Freon Adheres to all standard build platforms without glue or tape REACH and RoHS 2002/95/EC Directive compliant PRINTING GUIDELINES: Extruder Temperature:&nabs; 225°C – 235°C Platform Temperature:&Room temperature – 40°C Glue and/ or blue painters tape is suggested if not using a heated bed. Print Speed:&nabs; Top and bottom layers: 10-20 mm/ sec (600-1200 mm/ min) Infill speeds: 15-35 mm/ sec (900-2100 mm/ min) Layer 2+ use cooling fan if available.

## Features

- Truly flexible - no fill or layer manipulation required to achieve performance
- 660% elongation allows for repeated movement & impact without wear or cracking
- Excellent vibration reduction
- Shore Hardness = 85A
- Suggested Applications: Seals, gaskets, plugs, leveling feet, protective applications

    Experiment with this filament - small changes can make big differences
  

*by D***F on Reviewed in the United States on October 18, 2017*

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.

    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.

    Fun stuff, lots of interesting applications.
  

*by P***K on Reviewed in the United States on March 18, 2017*

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.
