Description

A simple solution to keep filaments dry even when they're stored in Bambu AMS for a long time. While AMS does store filaments quite well with airtight container, I just wanted active drying solution implemented as I have been running all my Prusa Printers from Dry Boxes and got really used to not worry about humidity and filament storage. Now, with AMS also I can simply plop in ASA, PACF and other hygroscopic filaments and not worry about them catching humidity.

Printing

It is absolutely necessary to print this model with filament that can withstand high temperatures close to 150 - 200 degrees centigrade. I used Bambu PAHT-CF and it has worked perfect so far.

Filament Used: Bambu Lab PAHT-CF
Perimeters: 4

Assembly

Assembly is quite simple, and you can refer to assembly guide attached in the files section.

It worked great, the instructions and bill of materials were easy to follow and effective. I did find gluing all the pipe pieces to be a bit of a pain, so there might be a better solution there with interlocking couplings. also it seems I am not getting enough airflow so I think I need a stronger fan, but otherwise it works!

@TheNiels

How does this work when you have different filament types in there (eg PLA, PETG, ASA) that each need a different temperature to dry at?

The designer has replied

@JalShah

I basically set the temp at 60F to 65F inside. At this temp, you might not be able to dry the ASA, but you can definitely keep ASA dry while stored for long periods.

Replying to @JalShah :

Does it have to stay running 24/7? How is the sound, is it pretty quiet or loud?

@JalShah

Replying to @TheNiels :

I have kept it running for last 10 months. It basically turns on when the temp goes below 57 and stops once the temp reaches 60. So it turns itself on and off. The sounds is basically non-existent, but if you're very sensitive to sound, then you can use quality noctua fan for quite operation.

@LyXAsuna

Hey, i followed the electric diagram and it ended up working the opposite way! when the temp is above the required temp itll turn itself on, any tips?

The designer has replied

@JalShah

The good thing is that you've got it working. The electric diagram in fact will have nothing to do with it working opposite way. What you need to in fact take a look at is the setup of Temp Controller. Take a look at the manual of the controller and you'll find the setting for when to turn it on and off.

Figured it out! thank you :)!!

@LyXAsuna

will PC filament be enough? Or do I need to aim for higher temp resistance filaments?

The designer has replied

@JalShah

The Heat Deflection Temperature for PC filament as per bambu is 119C and for polymaker, it is in the realm of 99C to 110C. PAHT-CF in comparison has the Heat Deflection Temperature of 194C. Based on these numbers, I wouldn't recommend PC. The temps right at the heating element surface may easily reach 100C - 120C for the AMS to reach about 55C - 65C temp.

Replying to @JalShah :

I see, ill try to get PAHT CF !

@SlowEvo

This is next level... Well put together instructions and diagrams. if I were a better tinkerer I would certainly make this.

The designer has replied

@JalShah

Thank you for kind words. :)

@LyXAsuna

Hey! mind telling where u placed your temp sensor? :)

The designer has replied

@JalShah

I place the temp sensor inside AMS by running it from the pipes.

@LyXAsuna

I print mainly PLA+, which surely requires less heat for drying (I assume atleast), will this also work as a good dryer for less intense heat materials?

The designer has replied

@JalShah

Absolutely!
