In addition to vacuum sealing, I also put a small amount of desiccant (silica gel) because... basically all plastic is water permeable. So even vacuumed sealed bags will allow humidity from the air to reach your filament. (If you know any chemistry, water is actually a very small molecule. Its smaller than Oxygen (O2) and Nitrogen (N2) which are the majority of the air (which explains how something can be mostly air tight, but NOT actually able to stop water molecules passing through. Water is actually smaller than most of the components of air.) EDIT: Just to be clear, this won't happen quickly... but it does happen over time, and can be important for longer term storage. This is also why filament, despite being usually sold in vacuum sealed bags, almost always has desiccant. If it sits on a shelf for a while (A year or more) before being sold, it would start to get wet otherwise.
I just bought one for my Creality Ender 3 v3 SE and I found that the flexible tube that the filament slides into tends to get pulled hard whilst printing rather than the filament sliding through it.
This saved my prints. I tried everything to fix my failed prints. Friend told me about this. Got it. And oh my god. I can't believe this was the solution. I live in florida. So very humid. I always noticed my prints work great the 1st day I opened them. But never put 2 and 2 together.
Regarding the plastic to plastic interface, i.e. not perfect seal of the box, I would think that this could be a good thing because when you dry the filament you want the moisture to be able to escape the box somehow and not be trapped inside. But yes, obviously the chamber will only be effective while actively drying because of this. It’s a trade off, but probably a good one.
just know that there is an issue with the hygrometer getting stuck and saying 15% at all times. I didn't realize this until after my return window had expired. Looking at many pictures it shows 15%. So I think this has been an issue for some time even before launch as even their promo pictures show 15% on stock photos.
Great video Daniel. I live in Eastern Canada close to water. So humidity is always an issue. In the summer there are a lot of days when I see over 80%. I do run a humidifier in my basement close to my filament and printer but a filament dryer is still needed. I picked up an Eibos single unit a few years ago and it's OK. I recently picked up the Sunlu S4 and I do really like it. A bit expensive though but works well. I looked at the creality one but I am glad I didn't buy one. Seems like they cut a lot of corners on that one. And every reviewer seems to have the same opinion on it.
I don't mind the dryer but I find if I'm using grainy filament the ptfe tube keeps getting pulled into the box and stops the filament from being pulled out by the printer I have a K1C printer ..please help
I found that when I first tried to turn on the unit, I was pressing the screen icon too hard. A very light touch as it is a lcd type screen. Just put your finger on it lightly and hold it. Hope this helps.
Looking to buy my first dryer. I do not use Silica, I use activated alumina instead. I need to buy vacuum bags and a sealer quickly to store things for a long time.
I have a Comgrow filament dryer and it only goes to 55C which is not hot enough for filaments like ABS and ASA. The Comgrow filament dryer is not very good as I have had to take it apart to fix the loose fan. I was looking at the Crealiy one as a replacement so I am glad I watched your review as though it looks fancy the quality does not appear to that good. I think I will look elsewhere for one.
For anyone unaware there's two different styles of Comgrow fliament dryer. The older one, which you have, and a newer one that is basically the Creality box in a different form factor. IMO the newer Comgrow box is better than the Creality version because it's easier to get a seal on it, though that does require getting some sort of silicone sealant to achieve a perfect seal around the lid. Otherwise the complaints in this video match up perfectly with the newer Comgrow model.
@bruwin You are talking about the newer SH02? Yes, that is not bad and goes to 70 degrees C. I wish they made a single roll version as I don't normally need to dry more than one roll at a time.
You shouldn't have to vacuum seal the bag if you store the filament with a dessicant (or silica) packet. As long as the bag is sealed, the packet should remove the internal moisture for long term. I've had perfect success with dessicant packets and a large ziplock style freezer bag.
Stick a large silica pack in a ziplock bag and then use a straw to draw out most of the air as you close it. Not quite vacuum seals but makes it easy to reduce the air and bonus the bags are nice and neat.
Not sure what the point of a timer is if the box isn't sealed. I use a Eibos that has a knob, set a timer on my watch, then put it in my AMS or sone of those bags. There is a lot of added cost to one with those electronics that in the end don't really do anything. If you aren't in the room when the timer goes off it will just start absorbing moister. This is why I like mine that doesn't go off and the timer is on my watch so if I'm not right next to the dryer then I'll still know it has completed the cycle but will still stay on if I can't get to it right then.
It's a piece of crap. They should have put a humidity sensor in it, I mean WTF! The hot air evidently messes up the LCD so it looks like a broken etch-a-sketch. This isn't rocket science, someone needs to do this right but this attempt is abysmal!
First few seconds of your review really turned me off this. Interface is such an important part. Also why is there no integration so i can trigger off an actual print? I want to be able to just pop it in my start print and leave it. This is effort.
@@Crosslink3D not sure, only had the k1 from them and haven't even looked at support yet. Bottom line is it's all open enough for me to rip out closed stuff if needed.
any filament dryer that fails to seal is pointless... Just set your bed heater to X degrees and put your filament on it, then put the cardboard box over the filament with a few holes poked in the top and a thin strip along the bottom cut away to allow hot air to rise and cool air to come in from the bottom. its free... comes with any printer that has a heated bed.
lmao how contradictory. "Any filament dryer that fails to seal is pointless" followed by " Just use your heat bed with a cardboard box with holes". Which is it? Dryers cannot be sealed because you'll trap all the moisture inside the box. There needs to be airflow. You shouldn't be storing filament in a dryer anyways.
The dryer is garbage. Touch screen feels unresponsive and awful, in addition - included pfe tube keeps slipping inside the dryer effectively stopping filment pull. Unfortunately I discovered this after my return window ended. Better buy something else instead and do not bother with this device

Most important thing is missing...How good it is drying the filament?!
It works well. I have the dual spool version.

Can you do a delayed start, if so how please? There is NO manual anywhere…

I consider this chamber heater in the printer because it have heater and bored controller is it possible
what is the max spool size I can fit there?
Welcome back! you have been missed!
Happy to be back making videos!
is 220 volts compatible?
Looks great but i think the Sunlu S4 is better for multiple spools.
its also huge.

Can you link the vaccuum bags you use please? I can only find larger ones

Is its vent too noisy ?
I was surprised how loud it was
Hello, which electric pump have you got? Looks like a useful tool but a bit of a minefield out there in terms of of quality
Ignore me. Those links list all the vacs not just one he uses. Damn
I don't think the vac he has shows up from that link. Its not the Creality, ELEGOO, "Vacbird" lol, eSun, or the OVV3D one.

Get one por two Dehumidifiers for your shop!!!…
LCD isn't good enough for you nowadays for $50 lol?

the lid not being sealed is still a ton better than being out in the open. i dont think thats a fair point
I wish i had that much filament

The integration is actually something that should be doable for creality, but will they do it?
