Thinking of buying a dryer to work with Core One
Hello,
I have been seriously considering buying a dryer for my filament to make my prints a little better. I keep my printer in the garage and it gets a bit moist in there, but it's better than in the house. My prints aren't terrible, but I think a dryer would help get rid of some stringing.
I was looking at a Sovol SH02 or something like that. My concern was feeding the filament into the Core One with the position of the bowden tube, and the SH02 doesn't look like it would feed well. I really don't want to perform surgery on the Core One, since I am not an advanced 3D printer so I don't want to start re-working the feed or anything. I'd prefer to leave the printer itself alone.
Does anyone use specific dryers for their Core Ones? Does it matter if I take the roll out to print? Does THAT much moisture get into the plastic in such a short amount of time?

Sunlu S4…. Yes, you absolutely need to have a dryer because even stuff coming from the factory may not be dry.
For example, I bought some overture PLA and it turned out to be breaking left and right and I couldn’t figure out what the hell is going on. Turned out it was wet from the factory… and it actually needed more than five hours of drying.
RE:
I use an external dryer 100% of the time. I do see changes on very long prints, more than 12 hours, but not enough to try to print directly from the dryer. I just pull it out of the dryer, start the print and put it back in the dryer overnight for the next day's prints. Cooking 8 hours or so a day seems to be sufficient for Prusament PETG, ASA and TPU at least. As I posted elsewhere, no amount of drying will keep Prusament PETG V0 from stringing.
Regards,
Mark

I've got an Eibos Polyphemus and it's working fine for me. It's got the ability to feed into the printer (you have to remove a little rubber plug then feed the filament through the newly created hole) but I've done the same as others here and just taken the (cooled!) filament out of the dryer and slapped it on the feed spool.
You've got me thinking though - next time I do a TPU print, I'll try the feed-direct-from-the-dryer and see if the results are better (that said, the Core One does a pretty good job with TPU, excepting the blobs that weld themselves to the print head - and cleaning an ObXidian is not fun)

Hello! I consider a dryer a mandatory accessory if owning a 3D printer. PETG, ASA, TPU are all quite sensitive to moisture, and just print horribly if they're too wet. Even PLA can get stringy and messy if wet. The only other solution if you don't have a dryer is to get fresh silica gel beads, place them in the same air-tight container as the filament, and wait for a few days. (You could use the oven to dry your filament, but seeing as filament ranges from health-detrimental to outright dangerous that seems like a really poor idea).
I own the Creality Space Pi Filament dryer. It's kind of shit, but I also am not convinced of any other dryers that are better. I dislike it because the fan sound is very annoying (although I'd much rather have a fan than not for performance reasons) and because you need to leave the door slightly ajar / open during running for the moisture to get out, which just feels wrong and like a poor design for a dryer.
Depending on what filament you're printing with and how humid it is in your room, you might actually need to print directly from a drybox. I've had long prints with PETG and TPU that went worse towards the end because the filament had time to get wet in the humid environment of the 3D printer-room.
RE:
I have actually ordered a dryer and it should arrive today 🙂
Up until now, I have been putting my filament in tote boxes with a little desiccant. Not the best method. I use PLA exclusively, but I do want to try TPU when I am able to get my hands on the Advanced Filter unit.
But I am not a professional at this, just enough to cause trouble.
My Garage is very humid. I am going to try to run from the box, I just don't know if I can feed it without bending it quite a lot between the heater and the bowden tube. We shall see.

Great news on the dryer - although most of the printy guys at work don't bother with them.
If your environment is "very humid" then yep definitely buying a dryer is a good plan. However, what's that humidity doing to your Core One??
I've been printing TPU without filtration - that said my Core One is within 4-5 feet of a large south facing window and we get good winds. I can recommend Sunlu's 95A TPU for being fairly decent to print with (minimal fuming) but lawks a-mighty does that suck up moisture like a sponge ... I left a reel out for 3-4 days on the printer and when I printed it I got the characteristic crackle/popping of water contamination (and the resulting print was like sandpaper with layer adhesion issues). Post 5.5 hours in a 60C dryer it was back to normal. But of course we're all using Prusament exclusively... 😉

Look up DIY Cereal Container Dryboxes.
I'm using the smallest/cheapest eSun dryer with two of these cheapo hygrometers put next to the rolls (they stand on the isolation foam-tape, leaning against the roll).
A nylon bag with silica gel inside the roll-hole and I replaced the fan with that tiny Noctua fan + shroud from some DIY manual. The original eSun fan isn't loud, but its whine is really annoying..
Venting the dryer every 4-8 hours, rotating the roll a bit and checking the hygrometers. If they don't go down any further between before venting and about 30 minutes after venting, the filament is done drying.
Prepare a drybox, then open the dryer, put the filament into the box, lead the filament through the ptfe tube and then fill the silica gel container for the drybox and close the drybox as soon as possible.
I'm using some 1 kg clear silica gel balls from a local chemicals shop.
When the hygrometer in the drybox goes up, I put the silica gel into another container, where the "wet" silica gel is stored an's re-fill the container of the drybox.
Whenever I feel like drying the silica gel, I put it onto a big, deep ceramic plate and dry it carefully in the microwave (watch videos and read tutorials!!!).
Doing this, I only have to purge some filament, if I hear some bubbling during the first layer (or already during purging), to get rid of the wet filament from within the Core One / ptfe tube.

I've been wondering about the effects on the printer... But all things considered, I would rather the printer stay in the Garage for now. I'll just deal with it.

I have good results using a food dehydrator and vacuum bags for storage. Ambient moisture here is 60% in summer.
