I wanted to brainstorm a few options for storing Bridge Nylon. Everywhere I read, people are saying nylon filament sucks up moisture like a sponge, and I wanted to find a way to keep it from doing that. I would also like to find a way to keep the filament in this container when printing. A couple ideas:

1.) Keeping it in a tubberware container with a bowden tube going out of it. It would also have silica packets inside. I found this on an instructables page about printing nylon.

2.) Storing the filament inside a bag full of the the silica packets or rice.

Do you guys have any other ideas?

Hey Jake,

the first option is sort of what I use. The container is both storage and printer feeder container.

I would strongly discourage from using anything but silica for moisture prevention (the best silica is the orange coloured variant that turns green to indicate saturation). Rice, kitty litter or the likes have some dust in them, which ends up clinging to the filament and ends up in the hotend. Nasty.

Sincerely,

Jonas

Could you elaborate on how you store/dispense the filament? I am very interested in doing that, since it seems like the most convenient way to go about using nylon. What container, how it’s modified, how you keep frictionless motion around the spool, how you get the filament to the extruder, how many of the packets you use in the container, etc.?

Good advice on the rice and kitty litter, I hadn’t even thought about dust.

Thanks!

I’ve never heard of baking PLA before. I was planning on baking the nylon at some point in the near future. I’ve heard you need to bake the nylon at 175 degrees for two hours. Is that in Celsius or Fahrenheit?

Keeping it in a sealed bag with silica gel is the best way to prevent moisture in the filament.

If the filament has too much moisture in it already, a good idea is to dry the filament in an oven at low temperature for a couple of hours. That’s what pva manufacturer actually recommend before using their filament. It is not very practical but it is the best way to “fix” the problem.

Got it. Thank you!

Sorry, it’s a typo. I meant pva. My auto-correct changed it to pla. To give you an exemple, Layfomm pva filament should be dry in oven at max 80 degree celsius (around 175 degree fahrenheit) for 4-5 hours. I guess that you can do the same with nylon. 80 degree celsius is definitely too hot for nylon but below the glass transition point of nylon should be a safe bet. Somewhere below 45 degree celsius would be perfect.
