NinjaFlex Fire 2.85mm is a specially formulated thermoplastic elastomer (TPE) that produces flexible prints with elastic properties.

 

NinjaFlex is available in 2.85mm and 1.75mm diameters in a range of colours. It has high elasticity and is REACH and RoHS 2002/95/EC Directive Compliant.

 

Each 2.85mm NinjaFlex spool contains approx. 750g of filament.

 

Due to the large variation of monitors, video cards, operating systems & Internet browsers and the effects each has on each other, the colours on this page may not exactly match the materials.

Does NinjaFlex work with all desktop 3D printers?

NinjaFlex has been used successfully on many FDM/FFF 3D printers, but it has not been tested on every model. In general, NinjaFlex performs best in printers with direct-drive extruders using settings similar to standard rigid ABS filament.

 

Will NinjaFlex work with Bowden extruders (push feed mechanism)?

Bowden extruders are not ideal for printing flexible filaments such as NinjaFlex due to the excessive distance between the stepper motor and the extruder head. However, some users have generated successful prints using reduced speeds.

 

Are there specific printer settings for using NinjaFlex?

NinjaFlex generally works well at similar extruder settings to ABS. However, adjusting the printer’s retraction settings can improve stop/start print quality, and it may be necessary to reduce the print speed to approximately 30mm/s. 

 

What are the processing guidelines for NinjaFlex?

  • Recommended extruder temperature: 210-225°C (410-437°F)

  • Recommended platform temperature: 20-50°C (68-122°F)

  • Recommended print speed: 30mm/s

  • Max temperature for printed parts: 66°C (150°F)

  • Min temperature for printed parts: -30°C (-22°F). Below this temperature, printed parts will become increasingly brittle and may shatter

 

Will NinjaFlex feed well through plastic guide tubes?

While the low coefficient of friction surface of NinjaFlex has been formulated to reduce surface tack and allow the filament to feed more easily, the use of PTFE guide tubes may be beneficial to further reduce pull at the extruder.

 

Is a heated bed necessary for printing with NinjaFlex?

No, in most printers, a heated build plate is not necessary to successfully print with NinjaFlex.

 

Is it necessary to coat the build platform prior to a print?

NinjaFlex bonds well to most surfaces (including aluminium and glass, blue painters tape, etc.), so coating the build platform is not necessary. Kapton tape can be used with NinjaFlex, but the adhesion of the printed part to the tape may be stronger than the adhesive holding the tape to the build platform.

 

Is NinjaFlex able to accommodate any bridging (crossing open unsupported spans)?

Yes, NinjaFlex behaves similarly to ABS in this regard and may accommodate some small gaps.

 

Can NinjaFlex be used as support material?

Yes, NinjaFlex works well in prints with support material and can easily be removed once the print is complete.

 

Are there any safety concerns or considerations when using NinjaFlex?

NinjaFlex should be used in a well-ventilated area according to recommended operating conditions. TPE products are capable of releasing small amounts of fumes at high temperatures. While these fumes are generally considered tolerable and less odorous than ABS, care should be taken to minimise exposure, particularly among sensitive persons.

 

Any other tips for using NinjaFlex?

When switching from another polymer (such as ABS or PLA) purge thoroughly before starting a print. As with other materials, when preheating, use a lower temperature (~180-200°C / ~356-392°F) to prevent excess material from draining prior to starting a print.

 

How can I bond NinjaFlex parts?

NinjaFlex has a very low surface energy, so it typically does not bond well with adhesives. However, 3M trim adhesive and Gorilla Glue provide moderate bonding. The best way to connect NinjaFlex parts is with a hot knife welder.

 

Is NinjaFlex water resistant?

While occasional contact with water will have no adverse effect on NinjaFlex, the product will degrade and lose its elastic properties when submerged in water for extended periods of time.

 

Is NinjaFlex food or medical grade?

Although NinjaFlex does not contain any known toxins, it is not recommended for food contact or medical applications.

 

Is NinjaFlex chemical resistant?

While NinjaFlex is resistant to most oils, it is highly affected by solvents, acids, and fuels such as gasoline. If the printed part should need to be cleaned, a mild soap solution is recommended.
