SUNLU Filament Dryer S4 vs S2 vs Food Dehydrator
Do you dry your 3D-printing filaments? It can be a cheap Food Dehydrator, or fancy like the brand new SUNLU FilaDryer S4... or the S2 for drying just one spool. Which one is best for you?

IMPORTANT: I do NOT know if this will suit you well!
You probably need to modify them to fit the spools - it will void the warranty! This is totally on your risk.

Do you have a FilaDryer S2?
Tell me if you are interested in performing the same modification I did to make a tangent exit hole for a bowden tube in your dryer.
I still need to find an easy way for people to reliably dry a hole on the S2 Lid - I did mine "by eye", with a firm hand 😬

I have an idea for 'reliable drilling'. I would design a drill jig to print out of PLA, that would pilot into the existing hole and have a fairly long 'guide' hole tangent to the lid. With careful use, you can sneak up on drilling the hole without tearing into the sides of the jig. Make the hole very tight to the drill size to help guide and prevent cutting. Then you could share that file and the TPU new plug. I'm shopping for a decent one spool dryer and this review and your mod are pushing me towards the S2. Keep up the great work!

Loved the video. Very well made and edited and kept me interested throughout the entire thing. Not too slow, not too fast, just right. And THAT's very important! About drying, I never have dried my filament and barely store them in a box with desiccant. Could this be causing my random problems? I live in central Florida. Thank you again! Great video, just subscribed.

Great video. I’m going to subscribe. 👍🏼 I really enjoyed that you pointed out the flaw with the S2 and modded it with the adapter. I’d appreciate if you shared the model for that.
I have the S2. The main change I would make would be the colour of the lid. It's a smoky grey colour that is difficult to see through, but I think the clear plastic of the S1 is better because you can check what's left on the reel with just a quick glance.

Oh, there is no Orange color… Some photos of the product can cause lots of confusion: some images suggest an “âmbar” cover and some are so reflective that you could think it is just clear transparent… The product is a transparent gray, hard even to see which spool is inside.
Really cool that you got a preproduction model AND that they value your opinion. Solid for the business, and I instantly like you more given that they trust you with their product. I'm excited to see what more I can learn from you!

Thank you! So good to have you here, Dr. Igor 🤗 Absolutely! And we need to promote more the 4.0mm OD 2.5mm ID Bowden tube, as the default to feeding tubes. Of course, between extruders and nozzles that’s a different story, it needs to be tight. 👍
Great video! Some suggestions: 1. I like the idea of automation (setting it to begin heating 6 hours before I get to my lab, so filament is ready-to-go). 2. I second your Large diameter Bowden Tube suggestion, especially if this is feeding 2 printers, it may have longer to travel. 3. Location of the power-plug -- The S1 allowed units to be stacked flush side-by-side (power was in back). The S2 you can't stack back-to-back, as the power cable sticks out in the way (would have been better to put it between the feet, or in the lower quadrant of the curved portion, so power feeds do not prevent units from stacking flush with each other (or stacking snug with printer enclosures). Hope the S4 power cable is underneath the feet, and not sticking out on the sides.

Hi Thomas! Yeah, the side-plug can be an issue, wow, I didn’t think of that! The S1 has the connector at its back (if you put it side-by-side with a printer) as you envisioned. The S1 makes a lot of sense as a companion for printers on a shelf - the panel is “in the front”, at the bottom of the unit. The S2 is way more beautiful, but it makes sense only when you have the unit accessible from the lateral. Oh, it seems that the Bowden tube coming with the S4 has a bigger internal diameter - at least somebody commented it here somewhere - and I am happy that they did the change!

@MihaiDesigns I almost printed one of your filament boxes - they looked SO COOL, but it was a lot of filament for me back when I saw it… Your designs are VERY Pro.
I wound up making my own filament dryers and storage from old computer parts I had laying around and home depot buckets. Works great albeit not aesthetically pleasing. The main difference is I do not like using silica gel. I find it works but it can be slow to absorb and a pain to recharge. I prefer to use calcium chloride and find I get much better results from it. I wish these dryers would be designed in such a way that we would have more than one choice in desiccant.
Did you ever post a link for the STL for the S2? I'd love to add that mod to my S2!

Thanks Fernando!!! Oh, it was a pitty that the AnkerMake M5C arrived here on the VERY day you guys went back home… Very fun printer! And considerably faster than everything I had so far.
I have the S1, and found that the rollers on the bottom did not work well with some cardboard spools, especially those that were roughly handled in shipping and suffered from dented spools. The solution there was a conversion that was on thingiverse that involves a printed frame and uses skate bearings to make the spool turn using the inner diameter instead. It has been freely rotating since the upgrade and I wish they would give you the option of either using the bottom roller way, or a center axle way. I have a bowden coming out of the lid of the S1 in the standard location going directly in to my ikea lack enclosure and then in to my S1 pro, smooth as silk.
hello I just started 3D printing about a month ago and I love your video about the filament dryer.

Great to see you here @McGybeer 🤗 Yeah, if silence is a major concern, the S4 should not be your choice… But, really, side-by-side with the M5C, it doesn’t really matter, the fast-printing world is very noisy 😬 BUT, the drying performance is amazing: it reaches 15% RH very fast, about 30 minutes here. And yes, 50% is really high… it takes the whole day to reach this mark and I would prefer if it stayed in a more desirable range.
I didn't have a 3D printer until last Saturday so I missed out on the kickstarter. I ordered the S2 on Amazon since my TPU is WET. I'll be ordering this when it's available to non-kickstarters!

This would actually be an awesome idea.
I would like to know to what degree a S4 allows in moisture when closed, since this review says at 9:25 "time will pass and humidity will start increasing"
Great video! I love that you mentioned the amount of power these things use. I don't use my food dehydrator so much because it sucks around 300 Watts or so. I like the fact that the S2 only draws 50 watts! That's very efficient. The only things that I don't like about the S2 is that it's very unstable. It's easy to fall over. In my case, if I had that one, I'd have to have it sitting on the top rail of my printer as I feed the filament from the spools on top, directly down. So the S2 would need to be bolted down or held on some way. As well, for me, the filament would need to feed out of the box as low to its floor as possible. Feeding UP, then having a sharp angle down, would not work. Perhaps an idea for SUNLU would be to have several holes so filament could be routed at different angles and positions. They could have plugs for the holes not in use.

Thanks!!!! 🤗 Look, the S1 by far is not fancy (at all), but it has the advantages of being a nice side-companion to a printer: panel on the front, DC plug on the back, Squared as you pointed the stability advantage. And it is cheaper. The S1 is still a good choice if you think of these things.
get them to out in larger lower rpm fans to help lessen that noise

Hey, nice mod for S2. Where can I download the file for S2 tangent mod?
For the S4 the fans are presumably running from 24V or 12V, so it should be possible to swap in variable speed (PWM control) fans, that can run quietly at lower speeds to circulate the air when the box is not actively heating.

S2 now has a fan. I've looked into this and a filament dryer really should be airtight with some desiccant, that way the heat extracts the moisture and it's absorbed by the desiccant. The S2 doesn't have anywhere for desiccant so once the filament is dry, and the machine turns off, it will slowly begin to absorb again.

I agree - and not only that: the S4 really dries much faster. But most people beginning printing might prefer spending money upgrading the printer or buying filament… money is always something to be considered.

Would it be possible to manage and control it through WiFi? If not, it would be nice to have the option to add an ESP32 to extend the possibilities. I use Home Assistant, and there are infinite possibilities for automating filament drying.

It doesn’t allow any sort of automation and that’s a pity, now thinking of it! Good thinking!
I don't know if it's still possible to make a suggestion, but they could allow dividing the chambers to control filaments 2 by 2, to treat different filaments.

Well… that won’t happen. There is only one heater. But in truth, for PETG and PLA, you can dry them together without much worry about so specific settings.
Wouldn't be nice if this was somehow combined with the Bambu AMS unit. e.g. Put all the drying bits into the AMS Unit. The Super SUNLU Bambu AMS.

Is this S2 the one with the fan at the bottom or without?
@GeekDetour

The S2 I got doesn’t have any fan - it was completely silent. I realized there is a new S2 with a Fan and I asked Sunlu if they could send one for me to compare - they sent it and I will make a video soon.
I use a cheap air fryer that has dehydrate mode. This interests me, but I'd have to look at swapping the fans for Noctua ones.

So it makes the moisture go from the filament into the air inside the dryer. And then it's trapped there, practically forcing it back into the filament, because the filament is now constantly surrounded by very moist air. The desiccant might help a bit, but that also stays warm, which also prevents it from absorbing moisture.

I think what you says might apply for the S2 - the %RH drops way slower… also, it is just 50W. But on the S4 it definitely doesn’t apply: it drops from 50% to 15% RH in less than 15 minutes, I was paying attention to that yesterday…

@@GeekDetour The relative humidity drops just because the temperature increases. The amount of actual moisture increases. Where do you think the moisture goes? It's not as if it magically vanishes or goes through the walls. No, warm air can hold more moisture. By increasing the air temperature you make it possible to increase the *actual* (as opposed to relative) humidity in the air.

The box is not as water-tight as you think. Vapor can definitely escape. Maybe I need to make a shorter video: when I open the LID, the %RH start increasing immediately. On your theory, it would help to open from time to time, but actually, every time I open, it gets more “humid” inside. Closing, it starts to drop again.

@@GeekDetour The reason why RH increases when you open the lid is because the temperature drops. Once you heat up the cooler, less moist air to the same temperature you'll end up with a lower RH. A real dehydrator (e.g. for dehydrating food) has huge holes for hot, moist air to escape, while it sucks in cool, dry air (although it might have higher RH) which it will heat up (thereby lowering its RH) and blow across whatever needs dehydrating. If you just keep blowing the same air around then it will just get saturated with moisture until there's an equilibrium of dehydration and hydration. Small holes are useless for getting rid of all the moisture in the hot air. And you can try it. Put a damp piece of tissue paper (or whatever) in it, run it until it's dry(ish), note the temperature and RH, then let out all the hot air and close the lid again, and run it until you get to the same temperature as it was before opening the lid. The RH will be lower (assuming it's at all reliable, and isn't just a temperature sensor faked to simulate a humidity sensor).
Yes I would like to get the piece for the S2

Looser tubes are likely to be more problematic with flexible filament where it bending and bunching up can cause failures as well. This will depend on the filament hardness and friction specifics, the speed, the geometry of the tube bends etc of course.
@GeekDetour

Well, that is absolutely true for Bowden printers, trying to push the filament, far from the nozzle. But when the printer is direct drive - the extruder is on the printhead pulling filament - then the less friction the better.

Why not holes on the front and flip the spools 90 degrees. Makes more sence, then you can loadup 4 spools behind a mmu unit and do multicolorprints. Now it come out of the sides. which need a long way to go to a mmu unit. Might work dunno?

To my taste, all the spools side by side as you said would make more sense to distribute to one or many pribters. But overall I guess it would be harder to distribute the heat equally to all spools, internally. The way Sunlu did was easier: the heater is in the middle of the unit, so, heat goes equally to both sides and each spools receives the same amount of heat.
I would love to have a dryer for my 3KG spools! I have a lot of wet 3kg spools that need drying and I WOULD buy sunlus filament dryers if they had that option but since I cant even fit them in, there is no point in buying it :( edit: cross my comment, I watched further into the vid, thank you so much sunlu! I will definitely consider buying this 😄

Hi there! Most of the times, PLA and PETG come perfect from factory… but for me, like 1 in 10 come printing less than ideal - you hear a “frying” sound from the nozzle and it pops tiny bubbles - search for “wet filament” and you will find videos showing how it looks and sounds. BUT, any filament with Carbon Fibers get bad after you open, Nylon also NEEDS to by drying WHILE you print. I don’t even want to test now, I use my filament in a dryer while printing.

Se tu deixar a S2 aberta um pouquinho, ela chega a uns 11% de umidade
Nice looking dryer, but I wish companies that make them would stop directing the heat directly at the filament. If you're not printing but drying the filament the heat will be directed at one spot on the filament. This would inturn fuse the filament together, I've suffered from this with two different dryers the S1 & the Eibos Series X. The Eibos was the worse one for doing this as it was fusing the middle of the filament due to the heating element & fan in the center of the spool.

@@GeekDetour lol actually like in a cold place.. UK. But with me using PETG i have to dry the filament most of the time, the last spool I dried for 24 hours before printing & it was only when I was getting to the middle of the filament (just over 500g used) did the filament snap. I took the spool out and spotted that the middle of the spool had warped. On inspection I found the whole filament next to the fan out take had completely melted together. This was while the dryer was as set to PETG on the Eibos. So I lowered the temp to the PLA setting but just slightly higher and it still fused but not as much as before. I have just recently bought a 2nd one (Eibos) and found that the sticker for the temp dial is totally different between each box. They must have noticed the error but didn’t tell anyone, the PETG & TPU are swapped around.
