Can NinjaFlex be used with support material?
Yes, NinjaFlex works well in prints with support material and can easily be removed once the print is complete.
Does NinjaFlex hold similar detail to ABS or PLA?
Yes, once printer settings are dialed in, NinjaFlex should deliver similar detail to rigid materials. For tall thin parts, supports may need to be designed-in to prevent the model from flexing as the print head traverses.
How can I bond NinjaFlex parts?
NinjaFlex has a very low surface energy, so it typically does not bond well with adhesives; however, Gorilla Glue seems to provide moderate bonding. The best way to connect NinjaFlex parts is with a hot knife welder.
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 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 colorfast?
NinjaFlex filament is colorfast, and therefore, the color will not leach from the product.
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.
What is the maximum recommended temperature for printed NinjaFlex parts?
The recommended maximum temperature for NinjaFlex printed parts is 150ºF.
What is the minimum recommended temperature for printed NinjaFlex parts?
The recommended minimum temperature for NinjaFlex printed parts is -30ºC (-22ºF). Below this temperature, printed parts will become increasingly brittle and may shatter.
Is NinjaFlex able to accommodate any bridging (crossing open unsupported spans)?
Yes, NinjaFlex behaves similarly to ABS in this regard and may be substituted in prints designed for ABS.
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 minimize 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 (~180-200ºC / ~356-392ºF) to prevent excess material from draining prior to starting a print.
