What is the 3d filament dryer you choose？

Now, get 2 - 3 ft of 10" PVC pipe, put threaded end caps on it, fill with desiccant and use an aquarium air compressor to blow your ambient air in on one end, and let that bone dry air coming out the other end keep the AMS under a slight positive pressure…
It has to go through the media. The media isn’t acting like a magnet but for water molecules.

Sorry for my earlier flippant remark, as I just didn’t have time yesterday to post a proper follow-up.

So, yes, you are 100% right. The experiment is done, and I an confirm it:

The ultimate filament dryer

In terms of Vision Miner’s secondary advice, of using dry nitrogen or argon, I’m almost doing that, but presently with just normal desiccated air to keep the filament dry inside the drybox by supplying just a slight positive pressure: [20240926_161408] [20240926_161423] I’m using an an oxygen flowmeter to dial the pressure all the way down to just above zero. I’ve been running it 247 for two days straight, and only just a little orange desiccant turned green, so extrapolating from that, I…

I thought I had posted it earlier on this thread (which is the reason for my obscure Inception reference), but apparently I hadn’t.

So, now that we’re all on the same page, welcome aboard! The more the merrier.

At the moment I’m waiting on a shipment from China of a very precise differential pressure gauge that I’ll use to more accurately set the minimum pressure needed to maintain positive pressure without wasting dry air flow.
