What is Ninjaflex used for?
What is Ninjaflex Filament? Ninjaflex filament is a TPU (thermoplastic polyurethane) based material that offers flexibility, elasticity and high strength properities. This rubbery material is great for projects that need to be both flexible and durable. It’s ideal for making bumpers for protecting your devices.
What should my retraction be?
If you retract too quickly, the filament may separate from the hot plastic inside the nozzle, or the quick movement of the drive gear may even grind away pieces of your filament. There is usually a sweet spot somewhere between 1200-6000 mm/min (20-100 mm/s) where retraction performs best.
Does Ninjaflex go bad?
Re: Expiration Date on Filament? Yes Ninjaflex is like other filaments and will absorb moisture. Instead of becoming brittle like other filaments it will begin to lose other properties. I mainly deal with functional parts in nylon or tpe so drying is a must if I start to see problems.
What temperature should my Ninjaflex be?
between 225- 250°C
We recommend printing NinjaFlex at between 225- 250°C with a bed temperature of 20 – 50°C. For print speed start off with 30mm/s and adjust it up or down as needed to perfect your print (remember each 3D printer is different and requires slightly different settings).
What is NinjaFlex made of?
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.
How do I know if my retraction is too high?
Too much retraction results in little gaps, or even globbing due to air pockets within the print head. When your printer does not retract enough, visible oozing will occur as the nozzle travels. You will see filament stringing between features as your nozzle is not stopping material extrusion before moving.
What is a good Z hop height?
I like my z hop to be around 2 layers high so as I do the majority of my printing in 0.2 my z hop is set to 0.4. On my cr10 with 0.6 nozzle that I use for larger/draft prints I do a lot of 0.3mm layers, the z hop is set to 0.5 on that printer.
Does PLA filament get old?
When moisture gets trapped inside the filament it can affect color, durability, and finish. ABS filament may expire within a month of humidity exposure, while bio-plastics such as PETG and PLA may last one to two years respectively, without going bad.
Does PLA filament last?
I’ve heard people say that when stored in normal settings, filament can last up to 15 years, and how PLA lasts very long when stored away from moisture. While in an adverse environment, PLA is said to last between a few months to two years.
How soft is Ninja Flex?
It’s incredibly strong! I can’t quite get over how solid objects printed with NinjaFlex are. They’re soft in that they can be curled together, but will regain their shape easily. If you print a single wall of NinjaFlex (0.4mm thick) it will take a lot of force to tear it apart.
What should be the retraction distance for Ninjaflex?
When working with Ninjaflex filament, it’s generally recommended to enable retraction right off the bat. A retraction distance of 1 mm and a speed of 30 mm/s should work just fine, but feel free to increase the values if you’re still having stringing issues.
What makes Ninjaflex different from other 3D printing filaments?
The properties of Ninjaflex make it vastly different from other 3D printing filaments like ABS or PLA. While most other plastics used in 3D printing are hard plastics, Ninjaflex is only one a handful of flexible filaments. Thus, Ninjaflex and other TPU filaments belong to a class of their own.
What to do if Ninjaflex filament gets jammed?
DON’T get discouraged if you have some initial failures printing NinjaFlex. Remember to go slowly and don’t push too much filament through your extruder too quickly! And if it gets jammed, no sweat, just let things cool, take the extruder apart and it should be easy to untangle any filament that is jammed.
Why do I need so much infill for Ninjaflex?
If you have infill that is too sparse, the filament can sag or clump between supports, creating blobs that then stick to the nozzle and become clumps on outer surfaces. Flexible filaments often require more infill than their more rigid counterparts. For NinjaFlex, try to keep your minimum infill to 20%.
