- Filament dryers can be a game-changer for 3D printing, especially if you’re dealing with moisture-sensitive materials. In this video, I’ll explain what filament dryers are, how they work, and whether you really need one for your setup.

AMS should have dryer integrated. Especially considering the price of those things and the fact that heaters cost almost nothing.
Have you seen that new mod enclosure on ams?
Since I got my filament dryer I haven't seen any stringing ever. My wife dries the clothes indoors most of the time due to people here burning wood to warm their houses and the place outside smells like a coal mine.
My printer sits in my basement with humidity of 21% to 30%. I've seen many people claim they don't need a filament dryer but my experience is that print quality improves sometimes significantly just from drying the filament. Even with PLA. Can you print without a dryer? Yeah, but I wouldn't recommend it.
I'm in the exact situation you described. Just bought 5kgs of filament, a bambu A1 combo, a 0.2mm nozzle - and now I'm finding that I need another thing! One of the filaments is PETG, so I may just see how it goes before I put in another 100 bucks. I live on an island so there'll definitely be some humidity.
Can you just put the filament in a sealed container with silica gel packs that absorb moisture?
You could, but depending on the volume of your container and amount/type of descent it could take days to weeks if you are starting from a higher humidity. You would also need a way to dry your desiccant once it is saturated
@@Lewis-bd4hd The way to dry your desiccant is called oven.
i just put 10 spools in a vaccum bag to test humidity, in one hour it dropped to 20% humidity with only 4 filmanet reel dessicant containers.
I'm wondering about the need for one. I'm getting my first 3D printer for Christmas, the Bambu A1. I'll be storing my filament (PLA, PLA Wood, PETG) in a sealed container with plenty of dessicant packets, but how much could be absorbed as I'm printing? If a print takes 16 hours, how much might be absorbed in that time?
Desiccant really only removes moisture from the air. Filament is often be shipped with moisture already absorbed in its core, because water is used for most filaments to cool it after extruding. You need warm air to pull the moisture out of the filament, so desiccant won't really do much alone.
CNC Kitchen has a good video explaining different drying methods:

@@gothnate one of the best answers I'v found. thank you. I guess I'm working with good filament that had very low moisture to begin with.
That DIY dryer looks pretty nice. Are the plans available somewhere?
The instructions say leave the comgrow drier open a crack while drying. Are the two top holes enough?
Great video man! I was wondering do you just have the A1 mini or do you have any other printers?
The Kobra 3 combo is pretty sweet. My dryer feeds my printer. I’ve got a house full of aquariums and plants, so my relative humidity is pretty steep.
Just got my very first filament dryer, and I’m a bit confused about how the % humidity works. I notice it rises but never seems to drop. I purchased the newer dual Comgrow SH02 Dry Box dryer. Any tips or insights would be appreciated!
As a complete beginner to this- i just got bambu a1 mini with the combo that you can out up to 4 spools….but the dryer you mentioned that holds four rolls can also connect to the tubes- so then I wouldn’t be using the asm (whatever it is called that holds the 4 rolls on side of printer)?
Most people dry the filament in a dryer before using
if you have an ams and only 4 rolls of pla, your fine with your ams and dessicant in the ams. dessicant holders with hygrometer fitting for ams should be first prints. when you get into nylon, abs i think, or carbon fiber infused filament, you'll need something. im using a cheap vacuum space saver bags from amazon until I find the right set up. Inverted cereal boxes are good for X!C bambu because even with AMS unit, I can use non-bambu filament feeding from the back. you should also know that not all 3rd party filaments fit in the AMS.
dont forget he is referring to storing fllament for long periods. if you take pla straight out of box into ams unit, the unit will show a number from 1-5 for cabin humidity. if only 4 spools of filament and having fun with learning, hold off and you will pick up info and see what you need as you go. Save your money. don't rush out and buy everything you see on youtube.
I use a Sovol SH02 and love it. I have lots of several year old filament (like dozens!) and I've had great luck drying out everything and it now prints fine.
What's the best setup for printing from fru boxes on the A1 & A1 Mini?
A question that I had about the S4 and have not been able to get a good answer to is, if I am not feeding my X1C directly from the S4, should I not install the PTFE tubes into the S4? And, if not, should I use the provided plugs to plug all or any of the holes in the S4 and keep them there while it is drying or storing filament?
If youre not printing from the AMS for the x1c, and instead using the s4 as an external spool feeder then it would be idea to have a line of ptfe ran to the s4. Otherwise you will have a few feet of filament exposed to the air ready for the next print that could have ugly first layer issues. assuming you didnt unload it.
@@Penguinishy Don't think that's the question.
Hi, Great vid. I have a question regarding smell of PLA/PETG during printing. Due to my small space at home I am concerned about smell during printing. I don’t want to expose my fam to smell and pollution. Can you share any experience here? Thx bro, hugs from Germany 👍🏻
for me (bambu Lab P1S) the smell is almost not noticable on pla in my small living, even after 6 to 8 hour prints.
@@leroy11troythx for sharing. I am aiming for an A1 mini. So printing bed is exposed to environment. Any experience here!
to answer the question, yes it annoyed me to invest alot only to find out about filament drying my 3d printing company and others conviently leave out. what is more annoying is that he answers what a filament dryer but could have started the video like everyone elses instead of making you listen to whole video to have all of his links (affiliate?) "if you know what a filmanet dryer is and wondering if you need one, answer"no,not really if you go through spools in a week and not using special very moisture absorbing filament. if your new and don't know about filament drying, stay tuned and I will explain more" that would have got a subribe and thumbs up. be different. respect time of your viewers.
yes
Am I tripping out or do you have a fishkeeping channel as well?
HUST USE AN OLD HAIR DRYER ON LOW MODE AND 2FT AWAY .. IF YOU DON'T WANT TO SPEND THAT $$$$
I respect the grind to make content especially seeing how you're a small channel, but this is like the 5th printer related video of yours thats showed on my feed recently. And each one you say a whole lot without offering much. At the end of this video is still pretty unclear which direction you lean in the goal of the video to persuade of getting one or not getting one.
Negative negative on the dryers. All my filaments are a month to five years old and no problems. Pla and tpu.
how you keep them from brittling?
@ live in California. Once in awhile the end may snap but after that part the filament is all good
..xD buy Sunlu PETG, out of box it is so moisture that you cannot print single thing in any good quallity.. if you buy good quallity fillament (20 and more usd) you dont need dryer, you dont need special dryer even if you buy cheap fillament just dry it in oven 6 hours 50-70 Celcius degree, but if you print many things and use many fillament buy bigger dryer for drying 1 or 4 spools on month it is throwing money to garbage
have you tried the air fryer method? all my filament is mainly Bambu
@christosvolikakis1523 I'm telling about this, with Bambu fillament you dont really need fillament dryer, why to spend money on any dryer if you doesnt have print farm? When you print only 4 u, oven is enough, dont spend money on things that are not necessery xD
