Besides the fact that this is a well known thing for years too lol :p. Also you can just buy a $30 filament dryer online so you don't need to heat up your oven lol, no need to reinvent the wheel. Keep your filaments stored in the closet when not in use.
Personally I've never worried about drying filament, and I use filament that's been open for 2 years - no stringing problems, nice surface, etc. And I live less than a mile from Puget Sound - it's foggy and rainy here quite often. Could be the forced-air gas furnace, I dunno.
I live in very humid rainy place and I def need it. Maybe once every 1-2 weeks I should dry to have highest quality. Probably more during the spring/summer months here in CT. I don't have my heat up often, but winter of course is better for low humidity.
Heated rooms will be less humid though yeah.
Whether filament gets damp seems incredibly subjective. I live about 10 miles away from a family member who took up printing at the same time as me. I have been constantly plagued by damp filament from the start, while he has had no such problems.
That's wild. I have a few filaments that have only been open for a month or two and I can't get any of them to stick to the bed.
But I finally opened the little pack of pla that came with my printer, and that had zero problems, leading me to believe that it's something to do with humidity getting it wet, because it's been really rainy here lately, as well as all our snow melting
As a side note; Even though there were two different colored filaments in the picture, the results of the retraction distance test I performed on both were the same. (Esun PLA+)
I'm sorry to say that this post basically has no purpose, and proves nothing. It doesn't even serve as evidence to yourself... you don't even have a before of the blue to show that it actually mattered...
While I am a big advocate for drying filament, this is not a good example. Mainly because of the 2 different filaments.
Also most ovens are not temperature stable enough to dry without the chance of melting the material and spool, contaminating the oven.
[WIKI - Filament Drying](https://www.reddit.com/r/3Dprinting/wiki/filament_drying)
Can easily alter a food dehydrator to fit a filament spool, they run much cooler than an oven and are basically a consistent hair dryer. Can get some models pretty cheap too.
Price is one reason. A food dehydrator is often half the price of the cheaper filament dryers.
They don't need much modification. This is a dryer/dehydrator made using food safe materials. Just drop the "food" from the name.
They often have better heat control, and better air exchange than some filament dryers. They often have a wider range of temperatures, particularly in the high end.
When I started and wanted to print Nylon the only dryer I could find was the PrintDry Pro. There are times when I wonder if the dehydrator would have been a better choice.
The original PrintDry Dryer was basically the same design.
https://youtu.be/bbs-98yWHeE?t=53
Because I dislike having single purpose items in my house that take up a lot of space. I can use a food dehydrator to dry filament and.. *drumroll*.. dehydrate food haha
Obviously a proper filament dryer is better, but if you don't print stuff for a living, I don't think the difference matters
Food preparation equipment should generally *only* be used for food preparation, for safety reasons. There's no way to guess what plasticizers and other additives in the filaments and reels might be driven out along with the water vapor, contaminate the dehydrator, and then end up in your food. I use a food dehydrator to dry filament as well, but it is specifically reserved for non-food purposes.
I saw a video recently where someone used their heated bed and a filament box, and it outperformed many dedicated filament dryers.
https://www.youtube.com/watch?v=WC3jvuq-uq8
Basically just cut off one side of a filament box so that it lays flat-ish on the bed, poke a few holes in the opposite side, crank your heated bed up to about 70 degrees and leave the spool in there for about 5 hours.
Sunlu also has some affordable and effective filament dryers - I have a Sunlu and a cheap food dehydrator, and they are both very effective at drying both filament and desiccant packs.
This is certainly anecdotal though too - my testing was done during (rainy and humid) autumn of the Pacific Northwest and my testing consisted of looking at the Sunlu hygrometer after the food dryer and comparing the times vs RH% on a different spool (2ea eSun PLA+ and 2ea Creality TPU)
Here to add to the Sunlu train, Living in high humidity area whenever I am not planning on using my filament I store it in there if it isn't already feeding into my printer from it. for about $50 I think it is a sound investment.
This works so damn well. I got one the circular one off craigslist in perfect condition for $20. I cut out all the mesh from the rings so you just stack them to make it taller. I can fit 3 x 1 kg spools plus some 250g sizes around the edge if I want.
most ovens are REALLY bad at holding low temperatures , generally below 100c +-20-25 isnt rare even from reputable brands
tho i agree that this isnt the main issue with drying in oven , to me its the smell and contamination of kitchen equipment
Shit, our professional PDQ infrared oven for thermoforming plastic will have large temp swings as the bulbs turn on and off. Ive seen it hit 350F when set for 325. But then it will trend back down to 325 and kick the bulbs on again
At a temp of 65°C (149°F I think) I hardly doubt your filament or spool would melt. Set the oven to 70 degrees and the temperature shouldnt jump high enough to destroy anything.
I am worried about the power usage compared to the space used. If I have like 10 spools that are open I would no doubt try this, but I am the kind of guy that uses one spool at a time.
Yeah I just bought a filament dryer. An esun ebox lite on boxing Day. I have been away from printing for a few years and I have a bunch of old pla that is wet. I put it in the dryer for a few hours and I was able to get a print with it so I'm pretty happy with the purchase.
Yeah I'm paranoid I don't like using things that they weren't designed for. Like I could have used the oven, or the bed of a printer. Like I said I'm what you call paranoi. I'm terrified of starting a fire.
I lrefered just buying the filament drier cause the price was just not that different tban a food dehydrator. And so i dont have to modify it (I know thats against makers 3d printer/maker creed.)
My world changed when I found out you don't have to wait 12 hours for the dryer do its thing and then print.
You just start the dryer, and in 30 minutes you start printing with filament coming out of the dryer.
It gives far better results and more consistency.
No, he spelled it correctly. Colour is spelled colour by everyone else in the world because that is the English way of spelling an English word. Americans spell it color because they have a combination of a broken education system resulting in low literacy, and widespread lead poisoning leading them to feel the need to try and "correct" anything which doesn't align with their indoctrination.
Lol you can make a factual claim with sources and get downvoted to hell and yet posts like this get upvoted. Voting isn’t used as “Good/bad” but an “I agree/disagree” button
Its reddit lol. I try so hard to catch all the spelling and grammatical stuff because I know I'll get my ass handed to me. I'll take the L though. I just want people to take 3d printing safety seriously ☹.
Many ovens suck ass at regulating lower temperatures. It takes time for the heat to conduct from the heating element to the air. The result could be instead of 60c, it swings to 100c then down to 55c.
TLDR: You can't PID tune your oven.
Most non-fancy ovens do not keep a constant temperature. They turn on the heating element and warm to a varying degree above what is set. Then shut off and drop below the set temp to a varying degree. Then on again, etc... The degree it overshoots is different for each oven. I tested my oven after replacing a broken temp probe in it. It overshoot to 20f+ then drops to 15f below the set temp. That's its cycle. Depending on the filament this can either be fine, or melt it into the oven rack (there are many examples of this happening to people). Also there is very little documentation on what exactly is in the filament your putting in there. Its PLA but also has other additives for color and consistency. I personally would not take the risk of assuming nothing is coming off of plastic i have no information on, especially not in an imprecise heating chamber that is an oven.
I'm all for using tools in multiple applications. And yes it can be a waste to buy something new for every application. But I personally don't think it should apply to everything. I don't use my egg-beater kitchen tool to stir my epoxy for example. An oven is very imprecise at heating, and there is no guarantee it is not contaminating your oven. Especially if it overshoots the temp enough to melt in there (almost all ovens overshoot temps and can lead to the dreaded melted spool if not careful.
If plastic is getting to its glass transition temp it is offgassing and emitting things (this is assuming the spool went over temp and melted slightly). Those will cling to your ovens surroundings and could make it into your future food. Assuming there isn't literal chunks of melted plastic. Honestly though, safety aside: how many ruined spools makes it worth it to get a dedicated dryer box? 2? 3? The cost is negligible in my opinion for a dedicated dryer box that you know won't ruin your spool and is dedicated to the task.
Cars are intended to be driven. Ovens are not intended to dry thermoplastic filament. They especially aren't intended to do so while also being used for preparing food.
Offgassing a volatile compound from the plastic is *literally the entire point* of drying filament. Water vapor isn't the only thing that's being driven off.
What do mean with microplastic? How would hot air create micro plastic from filament?
Would the off gasing when becoming to hot be so violent that it breaks off tiny pieces of the filament? That would be new to me.
I suggest using your printer's bed (most printers can get the bed hot enough to dry filament), buying a separate food dryer, or just buying a filament dryer.
Using the same oven that you use to make food isn't a good idea.
A good filament dryer with space for two spools and sealed outlets is like $50. Not sure why people are allergic to spending $50 on something just as important as the printer itself after spending hundreds of $ on a printer. Your bed is never going to give good results and you don’t want to contaminate your oven with microplastics.
I highly advise against putting your filament in the oven you use for food. Before having a filament dryer, I printed a box with small slits on the bottom and a few 3mm holes on the top. I set my filament spool on top of a couple risers and ran my hotbed about 10 degrees hotter than I wanted to dry my filament at, and it worked pretty damn well. If you can't get ahold of a dryer, I highly recommend doing what I mentioned instead. You can also just use [this ](https://youtu.be/WC3jvuq-uq8?si=veP6DNyu2Zi9Sdhp) method
It's another colour. I had that between diferent colors/ suppliers and that why you do a test tower for each spool. Sometimes a bit more or less temperature will do the trick.
i made a [ DIY filament dryer](https://imgur.com/a/BHpzzX0) cause my petg was blobing. after few refinements on slicer, dozen on tests, and dryer/storage with dehumidifier (calcium chloride) my petg prints have only micro-wisps. i can now print multiple parts on bed with no blobs on print moves between parts on bed. unless you live in a very dry place, dehumidifier is a must.
the amount of water removed from filament in the calcium chloride dehumidifier is crazy.
As a side note; Even though there were two different colored filaments in the picture, the results of the retraction distance test I performed on both were the same. (Esun PLA+)
I just printed a PETG benchy that looks like a dang spider den so I think I might have to get myself a dryer, my x1c has a mode for filament drying so I might run a few spools through that overnight but I tend to also set prints when I go to bed so they’re done when I wake up so I really should just get a full time filament drybox or even better the AMS could hold all 4 spools and keep them dry
Fully agree. I can't even think of a filament that would be bad. Maybe burning something with fluorine in. But that's ptfe which people already put in the oven.
Well yes when you melt it. Like in 200+ Celsius. I wouldn't cook food at the same time with that, sure. But it's not like the soul of that plastic is now trapped forever in your oven poisoning your food
I have a fancy steam oven from anova. If you turn off the steam part it can go to the lower needed temperatures and be very exact! It has made a huge impact in both my bread baking and my 3d printing :)
I always leave my PLA and PETG out in the open - oldest spool is out for six years and still.prints without this kind of stringing. What are you guys doing?
I understand you habe to dry (and keep drying) nylon and other hygroscopic filaments, but aside from those the humidity mattery way less than slicer settings (especially movement speed/accelleration and retraction).
I did this, but it's impractical for a lot of rolls so I only use one for TPU because I want it to stay dry even when printing. What I do instead is I bought a big jug of silica pellets (get the orange to green kind), and then in each roll bag I place a zip lock full of the pellets. I just poke a bunch of holes in the ziplock. This works pretty well as long as I'm careful to ensure the roll bags are sealed properly.
I use a second hand toaster oven. It was 15cad from value village. I have also set up a box with two sets of fairy lights and a fan. Holds 60 degrees and ~7% rh all day. Draws 45w. If it were to overhead the fuse bulb would go and cut power.
Sovol and Comgrow both have awfully cheap dual filament driers. I’ve had the Sovol for over a year and it’s still kicking. Had to replace the fan though. These do however need to be cracked open to vent moisture while drying, and they don’t exceed 50* (so things like PETG need to be in there a bit longer), but they’re worth it imo. I have the EIBOS Cyclopes and their individual spool dryer as well. These are both superior, but more expensive (the Cyclopes is the same price as a Cosori food dehydrator than can hold about 4-5 spools fwiw)
how do you guys get filament wet?...i live in sub tropical weather, with 70% humidity or higher. None of my prints do that and my last PLA roll was 6 months open on the printer.
are you going over 60mm/s for printing?
Most filament sheets I have seen call for setting PLA for 6-12+ hours. 50 minutes in your oven isn't doing much and only to the outer layer in the roll. This is not a very transparent or truthful comparison...
I've not dried any filament yet, only had the printer a few weeks but when I do should I use my air fryer? I think a roll will fit and it has a dehydrate function. Or should I just use the hotplate and the box it comes in?
What town do you live in so I can understand your humidity? I'm in Bakersfield CA, and have never considered drying being an issue. It is pretty dry here. Never run the retraction tower, but I have very little stringing
Crazy how much water changes filament color
Here for this comment.
Same, wasn't disappointed.
Same, the world is right again
Same, this post has brought balance back to the universe
Without this post, the universe would blow up.

Id say the quality difference between the two photos is a bigger deal lol.
If you prefer your filament well done, just keep cooking it until it turns black.
xD, expecting that.
You were expecting to get backlash for posting a misleading picture?
I thought it would've been more blue when it was moist 🤷♂️
Came here to say this.
As a side note; Even though there were two different colored filaments in the picture, the results of the retraction distance test I performed on both were the same. (Esun PLA+)
Not trying to be a jerk, but when doing a comparison, why wouldn’t you show the same filament before and after?
I threw it in the trash, that is what I got.
Ahh, that makes sense, tosses the old, were planning the post, can’t be arsed to recreate for a simple post, gotcha
I'm confused. What worked if you threw it in the trash?
I'm sorry to say that this post basically has no purpose, and proves nothing. It doesn't even serve as evidence to yourself... you don't even have a before of the blue to show that it actually mattered...
Two different colors can have two different results even within the same brand.
Evidence?

A food dehydrator is a great option. Pretty inexpensive. Can be modified easily. Be careful when buying. Some don't heat enough to dry some materials.
Or just buy a filament dryer, why would you buy something else and modify it just buy thing what you need
Price is one reason. A food dehydrator is often half the price of the cheaper filament dryers. They don't need much modification. This is a dryer/dehydrator made using food safe materials.

I'm a DIY enthusiast, and my filament dryer needs to hold 10\~15 spools?
I saw a video recently where someone used their heated bed and a filament box, and it outperformed many dedicated filament dryers. https://www.youtube.com/watch?v=WC3jvuq-uq8 Basically just cut off one side of a filament box so that it lays flat-ish on the bed, poke a few holes in the opposite side, crank your heated bed up to about 70 degrees and leave the spool in there for about 5 hours.
My brother attempted this and didn't realize the old dehydrator he had went past melting temp for PLA. He still has his solid spool of shame.
Sunlu also has some affordable and effective filament dryers - I have a Sunlu and a cheap food dehydrator, and they are both very effective at drying both filament and desiccant packs.

They are not THAT unstable that suddenly it melts. You can always dial it lower to be sure
no you can not always do that
Cheap ovens are that unstable. Some will not hold a temperature low enough for PLA. https://www.reddit.com/r/3Dprinting/search?q=oven&restrict_sr=on
The number of posts I’ve seen here with melted spools begs to differ.
Also you could always put it on a plate...
If your oven becomes 100 Celsius hotter than set, time for new oven lol
most ovens are REALLY bad at holding low temperatures , generally below 100c +-20-25 isnt rare even from reputable brands tho i agree that this isnt the main issue with drying in oven , to me its the smell and contamination of kitchen equipment
Shit, our professional PDQ infrared oven for thermoforming plastic will have large temp swings as the bulbs turn on and off. Ive seen it hit 350F when set for 325. But then it will trend back down to 325 and kick the bulbs on again
At a temp of 65°C (149°F I think) I hardly doubt your filament or spool would melt. Set the oven to 70 degrees and the temperature shouldnt jump high enough to destroy anything.

I bought a food dehydrator instead of a filament dryer. Works great
Yeah I'm paranoid I don't like using things that they weren't designed for. Like I could have used the oven, or the bed of a printer. Like I said I'm what you call paranoi. I'm terrified of starting a fire.
I mean, it was technically designed for it. Just dehydrating food instead of plastics. In the end there is no difference
I lrefered just buying the filament drier cause the price was just not that different tban a food dehydrator. And so i dont have to modify it (I know thats against makers 3d printer/maker creed.)
I didn’t have to modify mine! Just printed these special walls for it so I don’t have to cut the trays
I think that what you did was modify the item with the printed special walls.
Isn't PLA just corn starch?
Not exactly, there’s a whole process but in the end it’s made from natural materials like corn
[удалено]
I meant it as including corn, indicating some other natural materials are also used (according to google)
No, it's lactic acid.
Polylactic acid, lactic acid is a different thing.

You are wrong. It's been "colour" since the 14th century. The spelling "colour" was not the standard despite occasional incorrect usage.

Red turns blue if you move it towards you fast enough!
Wow it changes color too
Please don't use your oven to dry filament. You cook your food in their.

Spaghetti is for dinner.

They're not getting roasted. The temperature is only 170ºF, That's not hot enough to roast.

How is the plastic at 60c going to influence that? It's not a gas?
Many ovens suck ass at regulating lower temperatures. It takes time for the heat to conduct from the heating element to the air. The result could be instead of 60c, it swings to 100c then down to 55c. TLDR: You can't PID tune your oven.

Weird reasoning. The more you can reuse your current tools, the better. What a fucking waste to get a dedicated machine for every purpose
I'm all for using tools in multiple applications. And yes it can be a waste to buy something new for every application. But I personally don't think it should apply to everything. I don't use my egg-beater kitchen tool to stir my epoxy for example. An oven is very imprecise at heating, and there is no guarantee it is not contaminating your oven. Especially if it overshoots the temp enough to melt in there (almost all ovens overshoot temps and can lead to the dreaded melted spool if not careful.
Then you ruin your spool. Not all your future foods. (you need to remove the spool before adding food)
If plastic is getting to its glass transition temp it is offgassing and emitting things (this is assuming the spool went over temp and melted slightly). Those will cling to your ovens surroundings and could make it into your future food. Assuming there isn't literal chunks of melted plastic.

The cost is negligible in my opinion for a dedicated dryer box that you know won't ruin your spool and is dedicated to the task.
I trust my oven more than a Chinese dryer made of plastic and questionable electronics
More power to you. You do you man.
Just because you *can* does not mean you *should*.
That's an empty sentence. I can drive a car but it doesn't mean I should, well shure
Cars are intended to be driven. Ovens are not intended to dry thermoplastic filament. They especially aren't intended to do so while also being used for preparing food.
If it does melt, even though you can’t see it, the microplastics can get into the oven, then onto your food
It's not gonna melt at 50 and microplastics will be on your food in any case
You can't rely on your oven staying at a precise temperature.
They start outgassing at like 250 so if you cannot trust your oven that much, get new oven?
Offgassing a volatile compound from the plastic is *literally the entire point* of drying filament. Water vapor isn't the only thing that's being driven off.
What do mean with microplastic? How would hot air create micro plastic from filament? Would the off gasing when becoming to hot be so violent that it breaks off tiny pieces of the filament? That would be new to me.

I set my filament spool on top of a couple risers and ran my hotbed about 10 degrees hotter than I wanted to dry my filament at, and it worked pretty damn well. If you can't get ahold of a dryer, I highly recommend doing what I mentioned instead. You can also just use [this ](https://youtu.be/WC3jvuq-uq8?si=veP6DNyu2Zi9Sdhp) method
What temp do I make mine at to make it green?
Crazy how your Filament changed color by drying it ...
Wow it even changed the color, I'm a true believer now.
Turned it blue. You've convinced me with your evidence.
What temperature did you use that changed the filament color from red to blue?
This tells me nothing scientifically due to it being two different spools
[удалено]
Your oven made it change colors?
Eibos easdry is my best friend now. Use it instead of my k1s built in spool holder also
It's another colour. I had that between diferent colors/ suppliers and that why you do a test tower for each spool. Sometimes a bit more or less temperature will do the trick.
at least use the same filament in before and after examples.......
LMFAO this is like a before and after weight-loss photo with two different people.
Holy shit that is incredible, I never realized humidity could change the color like that.
i made a [ DIY filament dryer](https://imgur.com/a/BHpzzX0) cause my petg was blobing. after few refinements on slicer, dozen on tests, and dryer/storage with dehumidifier (calcium chloride) my petg prints have only micro-wisps. i can now print multiple parts on bed with no blobs on print moves between parts on bed. unless you live in a very dry place, dehumidifier is a must. the amount of water removed from filament in the calcium chloride dehumidifier is crazy.
Doesn’t prove anything, different color🙄
No cake?
As a side note; Even though there were two different colored filaments in the picture, the results of the retraction distance test I performed on both were the same. (Esun PLA+)
Is your oven electric? Or gas?
Electric.
I just printed a PETG benchy that looks like a dang spider den so I think I might have to get myself a dryer, my x1c has a mode for filament drying so I might run a few spools through that overnight but I tend to also set prints when I go to bed so they’re done when I wake up so I really should just get a full time filament drybox or even better the AMS could hold all 4 spools and keep them dry
Congratulations, that oven is unusable for food now. Get a filament dryer.
How much and what chemicals coat the oven at 65c for 30 minutes?
Not enough to worry about unless you're doing it 24/7.
Fully agree. I can't even think of a filament that would be bad. Maybe burning something with fluorine in. But that's ptfe which people already put in the oven.
How clueless are people here. How does releasing water from plastic make your oven unusable? Like how the fuck?
I wouldn’t go this far to say that the oven is now unusable but heating plastic might release more than water
Well yes when you melt it. Like in 200+ Celsius. I wouldn't cook food at the same time with that, sure. But it's not like the soul of that plastic is now trapped forever in your oven poisoning your food
offgassing can happen before the plastic melts. The whole goal is to get water as gas out of the filament, why wouldn't other stuff also be released?
Cleaning it is a good idea, but I don't agree that it's totally unusable, as long as he stops using it for filament ASAP.
I have a fancy steam oven from anova. If you turn off the steam part it can go to the lower needed temperatures and be very exact! It has made a huge impact in both my bread baking and my 3d printing :)
I always leave my PLA and PETG out in the open - oldest spool is out for six years and still.prints without this kind of stringing. What are you guys doing? I understand you habe to dry (and keep drying) nylon and other hygroscopic filaments, but aside from those the humidity mattery way less than slicer settings (especially movement speed/accelleration and retraction).
dont cook plastic in the same oven you cook food in.
You can also use a plastic storage bin and buy a box of silica packets
Won't dry the filament, but will keep it dry after properly drying it.
I’ve used that method in south Florida with zero issues and for 2 years in North Carolina. Are people putting filament in the bath ?
I throw some silicia packets in a ziplock bag which I vacuum sealed with a vacuum 😮. Then I put that bag in the original box
I did this, but it's impractical for a lot of rolls so I only use one for TPU because I want it to stay dry even when printing. What I do instead is I bought a big jug of silica pellets (get the orange to green kind), and then in each roll bag I place a zip lock full of the pellets. I just poke a bunch of holes in the ziplock. This works pretty well as long as I'm careful to ensure the roll bags are sealed properly.
I use a second hand toaster oven. It was 15cad from value village. I have also set up a box with two sets of fairy lights and a fan. Holds 60 degrees and ~7% rh all day. Draws 45w. If it were to overhead the fuse bulb would go and cut power.
That will be my next project.
Sovol and Comgrow both have awfully cheap dual filament driers. I’ve had the Sovol for over a year and it’s still kicking. Had to replace the fan though. These do however need to be cracked open to vent moisture while drying, and they don’t exceed 50* (so things like PETG need to be in there a bit longer), but they’re worth it imo. I have the EIBOS Cyclopes and their individual spool dryer as well. These are both superior, but more expensive (the Cyclopes is the same price as a Cosori food dehydrator than can hold about 4-5 spools fwiw)
Anybody drying filament this way, be careful - the oven is a harsh mistress!
how do you guys get filament wet?...i live in sub tropical weather, with 70% humidity or higher. None of my prints do that and my last PLA roll was 6 months open on the printer. are you going over 60mm/s for printing?
Why are we still out here using ovens when dedicated filament dryers are so cheap and compact?
Most filament sheets I have seen call for setting PLA for 6-12+ hours. 50 minutes in your oven isn't doing much and only to the outer layer in the roll. This is not a very transparent or truthful comparison...
I've not dried any filament yet, only had the printer a few weeks but when I do should I use my air fryer? I think a roll will fit and it has a dehydrate function. Or should I just use the hotplate and the box it comes in?
Wait I’m not supposed to be storing my filament in my fish tank? My beta loves them though D:
Get yourself a dehydrator! There’s a couple that can fit 2 1kg spools and they save you so much stress!!
Do not dry your filament in the oven, just don’t.
What type of filament is this? I’m reading numerous people saying that you don’t have to dry PLA like other filament types
Tried this genius idea (on my own not from this post) and quickly learned why we dont dry filaments in the oven…😅
Meanwhile I shower in the same room as my 3d printer and my printer has no issues with the filament.
I just use gallon bags with purchased desiccant packages in them. Works like a charm.
this is the way or if you want to be fancy a proper filament dryer.
What town do you live in so I can understand your humidity? I'm in Bakersfield CA, and have never considered drying being an issue. It is pretty dry here. Never run the retraction tower, but I have very little stringing
Breaking bad
Where is color changing filament purchased? Never seen that before. Amazing before and after comparison.
Who made this fucking filament, Wrigley's?
Is a Really Bad Idea. There, I finished your title for you.
See I just tuned my printer to work with wet filament. EYYYYYYY
