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.

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.

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. 

• 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

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.

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

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.

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

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

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.

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.

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.

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.

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

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.
