This Will REVOLUTIONIZE 3D Printer Filament Storage!

⚠️BIG UPDATE! ⚠️ 🔟%Since the video went into editing, I swapped ONE of the units to molecular sieves (another type of desiccant) + replaced the silica gel one more time... within HOURS, the humidity dropped to 10% and has stayed there for 6+ hours. THIS IS HUGE!!! 🎊Stay tuned, especially on @thenextnextlayer, for more updates.

dude, the whole rack you built is passing moisture not just through gaps but through plastic itself! to watertight plastic you need to coat it with like aluminium

good video, good effort ! aside of the not perfectly sealed enclosure, your test-results have one big problem, that maybe failed your measurements. you work wit RELATIVE humidity. the xx% your displays show is ALWAYS relative to 20° C ... now if the effective temperature is higher or lower than 20°, the shown % isn't correct. your collected data can fool you. download an app that converts temperature and relative humidity into ABSOLUTE humidity. you will get how much grams of water are in a cubic meter of air. these numbers are ABSOLUTE and are way better to compare with each other. you invested so much work and effort, you deserve true results!

I inadvertently found a hack. I have a 500 mm to a side Voron 2.4 and I am using the cereal box based single spool dry boxes. Because space is at a premium, I have a bunch of them sitting on top of the printer. I'm seeing relative humidities as low as 10% in one of the boxes. I am inadvertently getting some convection action by mainly printing ABS and having my boxes sitting on top because the driest box is currently at 83° f

Would love to see some up-cycling wine fridge videos

This video could have been half the length. Your verbose style apparently designed to increase watchtime is insufferable.

A big endorsement on the molecular sieve desiccant.
I work for a window manufacturer and we use molecular sieve desiccant in our sealed units. We buy it by the barrel and i definitely did not take a small container of it home to test. I was finding that a container of silica gel would take forever to lower the moisture in a dry box to sub 10% levels and often would only get it to 20%. However a small bag of molecular sieve just thrown in the container got the humidity down to sub 10% in less than half an hour. The stuff is very very effective.

Got a " stupid question " can i put my filament on my balcony when it's 45 deg c outside to dry it ?

Lithium chloride will get it to 10% or less, but it turns to a liquid so I has to be contained in a tray

Next step is to have controllable vents and heater inside the device so it can go through a desiccant drying cycle periodically. Close off the vents to the box and open external vent to release moisture outside.

You do such a fantastic approach to all kinds of situations with your videos, but videos, such as this one are directed toward the hard-core professional printer, which I am not. I’m an 83 year-old who just wants to do some hobbies work and maybe sell at a couple of local craft shows. I hope you will perhaps make a playlist for those of us who are not these serious hard-core print, farmers but directed to the very small time. Hobby printer like me because I find such huge value in what you present. I have enjoyed dozens of your videos, but now I’m more confused than ever about a beginner printer. What do you consider the very best easiest printer for a senior hobby printer? Thank you so much for all your hard work; it is truly, truly appreciated.

Trying to dry filament in a sauna created by spent desiccant, is a terrible idea. Do not dry your desiccant along with your filament. It's hard to coax moisture out of filament. Trying to do it in an environment with WAAAYYYYY more soaked-in moisture right next to it, is crazy

Lol. Imagine being upset about $14 spray paint when you own a thermal imaging camera. I mean I'm sure as a YouTuber you're earning a lot of your tools and filaments for free, but still, I mean a thermal camera is hundreds or thousands of dollars. You probably have $60-$80 in filament just in the drying cabinet alone. $28 (for 2 cans) is honestly just a drop in the bucket for a project like this. I mean even a bottle of desiccant is around $14 if you have the indicating kind.

Is there a sense of the total amount I absorbendkosirure in the box when full of say moderately dry filaments like in gram? Volume of sir at x %RH Adn y kg of FILAMENT AT Z% RHtherefore a calculable theoretical amount of descant (eg 1 kg / 20g water?) requires to absorb all that moisture?

Aliexpress 90c dryng hoven 15 spool capacity, 120 bucks, vacuum sealer for food 15 bucks, 1000 box vacuum bags 17bucks, silca baggies come with spools.
Total expense152 bucks, time wasted 0 hrs, energy requirement on long therm low, shelf life of dehidrated spools from 3 weeks (pa6) to 6 months (PC-ABS).
Wanna go fancy, professional sealer for metalized vacuum bags 80bucks, 1000 box vacuum metalized bags 90 bucks, shelf life from 3 months to years.
I come from open source but really cant stand people tryn to reinvent the weel, maybe it's just me tho.

Have you considered that the cabinet is sealed, so you are circulating the the air with no place for some of the damp air to escape. Most newer filament dryers have some kind of vent or else they actually accumulate humidity on surfaces.

I know you're committed to that cabinet but i would think building an enclosure thats better sealed, doesnt absorb moisture itself and designed to remove the silica cartridge externally or at least without exposing the whole compartment to fresh air would be better for maxing the dryness.

Having watched the video, in case I desperately need such a solution, I'd better saving up for the industrial one.

this is pretty cool! have you looked maybe into using something like Calcium chloride?

as for standard desiccant you will for sure need more volume of it for it. but i do like the idea of a no heat method.

You need to use flex seal!!

Can you try this electrolyte solid state dehydrator CNC kitchen tried?

and what about an hybrid approach using an heater to help and dry the silca itself adding a fan to extract humidity to the outside? this involve some valves and complexity but i think it's pretty doable anyway.

Think, using a salt like cacl2 is more effective. You can use the same setup, but need a bowl to catch the solution.

I’ve bought slice engineering activated alumina. LOVE it.

DO NOT touch with your bare fingers. You’ve been warned.

I'm using Molecular Sieve and the beads are 1.5 mm so they fall out of the current design. This is super cool though, love the fan, but need the holes to be smaller.

Hmm, I'll do this using a very simple box. I'll add your blower silica gel contrapment. I think it'll also be good for drying, not just keeping them dry.
