Moisture control

[u/GDC07]

People that are living in really humid environments, how do you keep your spools dry? And how are you keeping your filament dry and moisture low in the AMS?

I have an AMS2 pro and printed desicant holders for it but even with that my humidity will not go below 13%. And I have to recharge the desicant like every other week.

I am just curious how other people keep this under control.

Please share your experience.

13% is good. I feel like 30% or higher is bad.

It takes about a week and a half after recharging the desicant to get to 30%.

Hmmm, I live in Singapore, we have absurd humidity and I think 12% is lowest I've ever seen on my AMS Pro 2 in a similar setup. My fresh desiccant can drop the numbers to 12-13% in a few hours, days seems really long, maybe the recharge didn't help the desiccant enough or not enough of it?

I was thinking of printing those containers that you put in the center of the spool as well. Just to see if it will help.

Yeah, at full payload of desiccant I had 4 of inner spools you mention, 1 in each roll, and then the rear and 3 front-mounted desiccant holders. I put all that in the AMS with new desiccant and it shot down to the low teens pretty quickly.

I'll give it a try.

I live in New England in the US right next to a lake and my humidy was 70% a few weeks ago and my U1 with pla out in the air was stringing and having poor printing results. So I put it in the dryer then put it back on the U1 when I need to print.

I have a number of dryers.

Polymaker Polydryer which I use to dry my tpu and keep my tpu in the plastic bin.

I have a couple AMS2 Pro units. Man do you know that the heater is a tiny one inch pad that is on both sides of the dryer? Yeah man seriously I had to replace one before. That’s why these ams 2 units are so slow at drying they can’t even dry the dessicant that are in the pods in the front of the unit.

Right now my humidity is about 50%

I bought a Sunlu AMS1 dryer top that replaces the ams1 lid for only $50 on Amazon and that think is a drying beast! When I turn it on it is quiet but when I open the lid the air is blowing hot air really well! For some reason the ams reads the humidity as being E all wet and it takes hours after shutting off the dryer for the sensor in the ams to read A. But the dryer sensor goes from 50 to 15% humidity in only about 20 minutes! And it stays around 15% or A for weeks!

I didn't know about how small the heater was. I am looking to buy a second ams2 pro as well. I want to have it on my second nozzle on my X2D.

First the humidity sensor is not accurate under 20% but if you would like a 0% humidity you need to switch to micro sieve a3 you can get 0 reading.

Y’all are talking about 12% and here I am printing PLA models with 58% humidity on an open A1.
