This is PA Nylon filament as made by Flashforge. This is an incredibly hardy type of Nylon, making it perfect for intense and specific engineering projects. PA nylon has incredibly strong inter-layer adhesion, ensuring that your prints come out without cracks and splits, while still being very flexible when printed with thin walls.
This is a new-upgraded formulation engineered by Flashforge helps to minimize filament problems such as curling and bubbles during printing. The new anti-moisture ingredients included in this formulation permits longer storage time without loss of quality.
Nylon likes to print very hot, at around 230 degrees at a minimum when printed slowly with thin layers, and all the way up to 260 degrees when printed with thicker layers or at a faster speed. This can only be printed on a 3D printer that has a heated bed that can maintain a temperature of at least 90 degrees, and at bed 105 degrees.
Nylon likes to absorb the water in it’s environment. Once a Nylon roll is opened, either the filament needs to be used quickly, or when not in use, it should be stored in a plastic resealable bag (or other airtight environment) with the silica gel sachet that came with the roll initially to ensure the filament will last a long time in storage.
These spools will fit on nearly every 3D printer, having a large inner spool diameter. These filaments will work well with any printer that takes 1.75mm. They might however require an external spool holder if they do not fit on the spool holder that comes with the printer.
