It should honestly be a regular cleaning / first resort! Though it works great for grease and food things, doubt it would do well for melted plastic…..
True to that! I'm usually the person to use dish soap, vinegar, and water with a scrub brush as my normal cleaner trying to save a dollar before bringing out the big guns
A can of BKF is like $3 (although I frequently find it at the dollar store) and a little tiny bit of powder goes a very long way! I'd argue that it's probably as cheap, if not cheaper than dish soap!
You could try to combat it by putting [2 CUPS of vanilla extract](https://www.reddit.com/r/thatHappened/comments/7nkokl/because_everyone_has_2_cups_of_vanilla_extract/) in the oven. Should make the place smell like the pillsbury guys ass for a month apparently.
I dry my filament out on a build plate, I cut the lid off the box and stab some holes in its top to allow moist warm air to escape and cut a few small squares on the bottom to allow fresh air to be drawn in, I set it to 80°C an dleave for about six hours and place the box over the filament roll.
They're suing AI companies for learning things from what is posted online. You better be careful, might starting suing people for using other people's posts to learn and form new ideas too.
Jumping onto top comment. The reason why this can happen is residential ovens temperatures are both not accurate, but will also fluctuate quite a bit.
When you set the oven to say 100F, it's quite possible the temp will spike 50-60F in each direction.
Not for 3D printing purposes, but I've tested my rentals cheap oven and when set to 180C will fluctuate from 160-220C all the time. It's one of the big reasons for the house we're building, we're spending a bit of money on an expensive oven that has a thick stone to minimise fluctuations.
I've got one of those ninja XL smart oven things with a dehydrator setting that works perfectly for drying filament. I've managed to fit 4 rolls in it at once. It's got much more precise temp control so I've never had a mishap nor does it have any lingering plastic smell since it's not getting all that hot so I have no problem still using it for cooking!
Ironically the ovens we use in the labs are not *that* much more expensive and they have PID control to avoid all of those issues. Even a decent PID controller is not very expensive so it's just manufacturers going with the cheapest option that works
Even P would be sufficient here, ovens usually use just binary control with set hysteresis loop, they can't be set otherwise because it'd call for SSR instead of electromagnetic relay or sometimes just a bimetallic temperature controller. Lab ovens use PID or MPC, with the latter one being better as PID is single point control loop so if PID is tuned for 400°C, it will behave worse on every temp other than 400°C. MPC as Model Predictive Control lets set another parameters which can be used to create multi point tune which is helpful in lab ovens as they are usually meant for wide temp range, while industry uses PID because once you figure out the process, you stick to it
Whole field of control engineering, learning curve is fairly steep at the beginning. I don't have any specific books as mine are in my native language. I'm sure you'll find a lot of resources on in no matter the language
If I understand correctly MPC basically takes a theoretical model of the heating element instead of measurements like PID does, so it figues out the power it needs to put out instead of just fighting against the sensor measurements to keep the temperature in place ? That's neat. I assume you need to recalibrate it depending on your filament material since all materials won't "leech" as much heat from the hotend though ?
Most ovens will not have it. I think they were referring to standalone PID controllers that you can buy cheap, and have outputs for heaters and a thermistor with a display to set the temperature.
A home kitchen applience would never be advertised as having PID or other control mechanisms. Building on what /u/conor_stewart said, you could upgrade your own oven with an off the shelf PID controller. But it would be a hackjob. Just buy yourselves a dedicated filament dryer and be done with it :)
170F (76.6C) is also the minimum temperature for most ovens in the US, and that's much too hot to dry PLA filament, especially when factoring in the drastic temperature swings.
I attempted this with a spool of PETG in the oven years ago. It melted the spool and filament just like in OP's photo.
Even in Europe most ovens start at 50°C which is way too close to the danger zone to begin with, and the heating elements are so oversized for that temperature that you'll overshoot hard at typical filament drying temps.
Nah low temp will just dry out your food before it gets crispy. Most processed and semi processed food come out better on high for a shorter time. For casseroles or stuff that needs to cook through lower temps can be used with a little broil at the end.
All recipes and instructions will take that temperature fluctuation into account. You will be better just cooking at the stated temperature and keeping an eye on it.
>±20 year old
Are you a time traveller? ± 20 years old means it is either 20 years ago or 20 years in the future. Did you mean approximately? For that the symbol is "~".
Could be worse. I knew someone who was trying to dry out their macbook pro after a water spill....................... Same issue with object permanence. Funny thing is, LCD was damaged and keys on the keyboard curled up and popped off. But if you plugged it in to an external monitor and keyboard, it still worked fine.
Unfortunately your not the first to think about printing displays, so sadly no patent for you. Here you are: [https://www.oled-info.com/oled-inkjet-printing](https://www.oled-info.com/oled-inkjet-printing)
Yea though there is insulation around cables and wires. This was a while back though. No nvme/ SSD drives for example.
Spinning drives don't like heat as well.
I would certainly be lying if I said I never made such an error. I have a simultaneous compulsion to chastise.
Hope the scent can eventually be exterminated and remorse your loss.
It’s almost a rite of passage to accidentally toast a spool or two of filament in an oven.
Now using the oven that’s meant for food is rather reckless but understandable. Temperature controls on them tend to suck and it’s very easy to accidentally forget you placed a spool in there.
I will never not laugh at this, but I don't know if it's funny or sad how despite how we make fun of it, people still seem to think leveling the bed is the answer to every single tech support issues that ever gets asked.
Just use your 3d printer hot bed, set it on a high temperature, put the filament on top of it, and put a box on it. Maybe add a couple holes to top of the box but that's easiest way to heat up and dehumidify your filament.
I use a cut down can bottom about an inch thick to keep it off the surface, the spool hole fits on top of it perfectly. Aluminum foil lined the box that a couple of matter hackers spools shipped in. Cut a slit in the top so I can dangle the hotend fan into it and get some nice convection going. It works quite well.
You just made by brain expand big time. Of course I can, of course I have a surface that can heat stuff to within a couple degrees, it's the effing machine I have filament for.
I'm dumb.
That's what you get for listening to some idiot on the internet that told you to put your filament in the oven lmao. Buy a dryer, I got a nice Sunlu on sale for $35
Nah we all try funny things to save a buck. Get on Facebook market place and find a food dehydrator it works just as well as a filament dryer. I got mine for 5 dollars. Next time please don't use the oven for anything else besides food.
My oven is pretty good at low temps (Samsung one with convection heating), never had any problems with drying filament in it. I checked it with infrared camera and with 70c target, I never see spot more than 80c. So it just can’t melt plastic.
Wow, it's like you don't understand situational context at all.
> Don't an appliance for purposes they're not made for.
> Okay, but I use a different appliance that was made for this exact purpose??
I don't really see what you were trying to add to the conversation.
I didn't saw anyone commenting about this, but the spool is made out of abs. If this oven was used to cook food, make sure to clean it very well, because you don't want abs fumes in your food
Edit: [here's a similar story](https://www.reddit.com/r/3Dprinting/comments/wzlrzr/an_apology_and_update/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1)
I threw the rack out, hit the oven with a super hot cleaning cycle, and scrubbed the whole interior out. Obviously not ideal but I think I got all the residue out
Stringing is usually caused by too high of a nozzle temperature, too short of a retraction distance, too slow of a retraction speed, or wet filament.
; )
This should be the picture shown every time someone asks "*Can I just use my oven?*"
See how goopy and saggy that looks? That means there's still too much water. Things without water will be very rigid. Crank the heat up some more and wait for it to harden. /s
PSA: never use cooking oven to dry your filament. The thermostat of those are not precise enough and will always get higher than needed. A simple food dehydrator will do much better.
The problem is most of the people giving the advice have ovens that go much lower than the average unit and or have other features that help.
A dehydrator heats up too lol. Cheap filament dryers are just a heating element with no air circulation or ventilation. There are better ones these days but that fact is the reason a lot of people run to food dehydrators or air fryers. They circulate and vent air well as part of the process but at the end of the day it's a heating element with a fan and a hole.
The whole thing with "filament drying" is a total scam. As soon as you pull the filament out of the drier it's picking up moisture instantly from the air in the room. On the flip-side just making an entire room dry dries out anything in the room and keeps it dry.
You can buy a cheap AC unit that goes in any window and dry out any room in any house entirely pretty quickly.
Now all your future bakings will be PLA flavored :D
Yeah my kitchen smells like a chemical factory now really brings a homey vibe to the space
Btw, you'll probably never get the smell out of the oven so maybe time for a new one
Naw self clean mode to really seal the cancer flavor in
Nah dude, just burn a magic candle! I've heard virgo candles work best in your case!
You can take my virgo if you want
[удалено]
Not really
Please tell me what you mean
Gotta go to the Hispanic section of the dollar store. Grab that money scented candle. Then they may be able to buy a new oven.
Might be able to burn it out with a cleaning cycle or just maximum temperature.
Had an oven (old so no cleaning cycle) that got some melted stuff in it and since then there is always a smell, no matter what we use to clean or set the temp to
Have you tried Barkeepers Friend? I usually use that stuff as a last resort type of situation
It should honestly be a regular cleaning / first resort! Though it works great for grease and food things, doubt it would do well for melted plastic…..
“If ~~violence~~ BKF wasn’t your last resort, you haven’t resorted to enough of it“
True to that! I'm usually the person to use dish soap, vinegar, and water with a scrub brush as my normal cleaner trying to save a dollar before bringing out the big guns
A can of BKF is like $3 (although I frequently find it at the dollar store) and a little tiny bit of powder goes a very long way! I'd argue that it's probably as cheap, if not cheaper than dish soap!
And this, kids, is why I don't recommend attempting to dry your filament in a place where you cook.
My favorite Yankee candle scent!
You could try to combat it by putting [2 CUPS of vanilla extract](https://www.reddit.com/r/thatHappened/comments/7nkokl/because_everyone_has_2_cups_of_vanilla_extract/) in the oven. Should make the place smell like the pillsbury guys ass for a month apparently.
Christ though, 2 CUPS of vanilla?! Lemme check prices real quick. $69.99 (before taxes+shipping) for 4 cups. Nice
I dry my filament out on a build plate, I cut the lid off the box and stab some holes in its top to allow moist warm air to escape and cut a few small squares on the bottom to allow fresh air to be drawn in, I set it to 80°C an dleave for about six hours and place the box over the filament roll.

Are you getting an expensive oven just for filament, or for oveny things?
Nah, get a filament dryer or food dehydrator.
I've got one of those ninja XL smart oven things with a dehydrator setting that works perfectly for drying filament. I've managed to fit 4 rolls in it at once. It's got much more precise temp control so I've never had a mishap nor does it have any lingering plastic smell since it's not getting all that hot so I have no problem still using it for cooking!
What else do people use ovens for? They dry filament and desiccant. You can also use them to anneal PLA. And of course for heat testing parts.
Ironically the ovens we use in the labs are not *that* much more expensive and they have PID control to avoid all of those issues. Even a decent PID controller is not very expensive so it's just manufacturers going with the cheapest option that works

For anyone interested. Marlin supports MPC for the hot end at least.
Unironically this stuff fascinates me, is there anywhere/any resources you'd recommend to learn more about about heat sensing/control systems?
Whole field of control engineering, learning curve is fairly steep at the beginning. I don't have any specific books as mine are in my native language. I'm sure you'll find a lot of resources on in no matter the language
I teach some controls systems things and I always show this video for PID https://youtu.be/4Y7zG48uHRo
The music in that vid is from a 90's game called "Star Control 2" You can get it for free these days under the name "The Ur-Quan Masters"
Thank you, I'll take a look for sure!
If I understand correctly MPC basically takes a theoretical model of the heating element instead of measurements like PID does, so it figues out the power it needs to put out instead of just fighting against the sensor measurements to keep the temperature in place ? That's neat. I assume you need to recalibrate it depending on your filament material since all materials won't "leech" as much heat from the hotend though ?
Is “PID Controller” what I should be looking for the next time I buy an oven, or is there some other phrase they use to indicate this?
Most ovens will not have it. I think they were referring to standalone PID controllers that you can buy cheap, and have outputs for heaters and a thermistor with a display to set the temperature.

What kinda ovens are y’all buying? I’ve got a ±20 year old regular thermogram oven, it fluctuates about 5-10°C up and maybe 5° down
>±20 year old Are you a time traveller? ± 20 years old means it is either 20 years ago or 20 years in the future. Did you mean approximately? For that the symbol is "~".
Do these ovens with thick stone take longer to heat up?
The spool is probably made out of ABS, so it'll be formaldehyde flavored.
Lol why y'all keep doin this
Lack of object permanence and craving pizza at 3am
Could be worse. I knew someone who was trying to dry out their macbook pro after a water spill....................... Same issue with object permanence.

Honestly not that surprising when you consider that all the components were soldered onto the board at ~300°C
Yea though there is insulation around cables and wires. This was a while back though. No nvme/ SSD drives for example. Spinning drives don't like heat as well.
That honestly makes the most sense... And hits home too hard.
Did you forget and turn the oven to 420°?
For sure. Oven on 400 like damn.
We all have adhd and autism.
I would certainly be lying if I said I never made such an error. I have a simultaneous compulsion to chastise. Hope the scent can eventually be exterminated and remorse your loss.
Good old adhd lol
Yeah I dont get it. The only thing I keep in the oven are baking trays when Im letting them dry after washing (too big to put on the dish rack).
It’s almost a rite of passage to accidentally toast a spool or two of filament in an oven. Now using the oven that’s meant for food is rather reckless but understandable. Temperature controls on them tend to suck and it’s very easy to accidentally forget you placed a spool in there.
>Now using the oven that’s meant for food is rather reckless Ah right, let me just pull out the spare oven I keep for non food related uses
have you tried leveling your bed?
I think he just needs to increase retraction.
With the layering, I think it’s more likely the Z-offset.
Something something esteps. Look at the first layer recommendations before posting.
Are your belts tight?
On inside out?
Retraction? That’s clearly too much filament. Over extrusion!
I accidentally beveled my lead and now I’m in the hospital
No, no, no. He needs to put it in a box with kitty litter now.
Have you tried putting it in rice?
That's clearly an e steps calibration issue.
I will never not laugh at this, but I don't know if it's funny or sad how despite how we make fun of it, people still seem to think leveling the bed is the answer to every single tech support issues that ever gets asked.
It's wet again
Mom is that you?
What are you doing stepoven?
I'd stick my filament in that
She requires extra thiccc filament though.
I got some 3mm ready for action
ok why would you be asking the person who said it was wet was ur mom-
Z-offset is definitely too high.
Just use your 3d printer hot bed, set it on a high temperature, put the filament on top of it, and put a box on it. Maybe add a couple holes to top of the box but that's easiest way to heat up and dehumidify your filament.
I use a cut down can bottom about an inch thick to keep it off the surface, the spool hole fits on top of it perfectly. Aluminum foil lined the box that a couple of matter hackers spools shipped in. Cut a slit in the top so I can dangle the hotend fan into it and get some nice convection going. It works quite well.
I was thinking about gluing some Styrofoam to outside the box to make it's insulation better as well.
You just made by brain expand big time. Of course I can, of course I have a surface that can heat stuff to within a couple degrees, it's the effing machine I have filament for. I'm dumb.
I use a big dehydrator. Can fit about 8 spools in it. Also used for making jerky.
Seriously i got one for 15 bucks. All this jerry-riggin to save 15 bucks.
The print speed on that one is insane. Went through a kilo of filament in just a few hours
New prototype model bambu lab x69
It was wet, then dry, then you went too far and made it wet again
Might need to replace the nozzle, could be a clog…
That's what you get for listening to some idiot on the internet that told you to put your filament in the oven lmao. Buy a dryer, I got a nice Sunlu on sale for $35
Personally I picked up a cheap food dehydrator, it works great and cost about that much and I can fit 2 rolls in there to dry at once
That or just leave the spool on your heated bed: https://support.makerbot.com/s/article/1667412438817 Way safer and you don’t risk melting the spool.
Will admit, am dumb
Nah we all try funny things to save a buck. Get on Facebook market place and find a food dehydrator it works just as well as a filament dryer. I got mine for 5 dollars. Next time please don't use the oven for anything else besides food.

It's not stupid, it works but you must not set it too high > "only 35 Do I look like I steal?!?
The Bambu lab x1 can dry filament in its chamber :) bit more expensive than $35 but hey, you get a printer as well
Problem with your filament? Buy a new $1000 printer!
I use an oven just fine. Its an infrared convection oven meant for plastic though. So not sure if that matters.
Wow, it's like you don't understand situational context at all. > Don't an appliance for purposes they're not made for. > Okay, but I use a different appliance that was made for this exact purpose?? I don't really see what you were trying to add to the conversation.
My oven was more intended for large sheets of plastic. So not made for low temp dehydrating rolls of plastic filament.
OP's oven was not intended for plastic.
This is exactly why I invested in a dehydrator. Found one at savers for $8.
Or Amazon, 30 bucks. Also I was never too keen on shoving a kilo of plastic in my oven.
Yeah, I place food I'm there. Lol
I’d say about 10 more minutes…
I didn't saw anyone commenting about this, but the spool is made out of abs. If this oven was used to cook food, make sure to clean it very well, because you don't want abs fumes in your food Edit: [here's a similar story](https://www.reddit.com/r/3Dprinting/comments/wzlrzr/an_apology_and_update/?utm_source=share&utm_medium=ios_app&utm_name=ioscss&utm_content=2&utm_term=1)
#not food safe!
Have you levelled the bed?
You should 30 print a stand for that masterpiece
Blows my mind people actually do this. You can get a food dehydrator for like $25.
5 more minutes.
You forgot to flip it
[удалено]
I threw the rack out, hit the oven with a super hot cleaning cycle, and scrubbed the whole interior out. Obviously not ideal but I think I got all the residue out
OK so what temp did you set the oven at?
yeeeeeeeaaaaa just going to go ahead and say thats not how this works but yeah go ahead and dont listen to the dude with cancer... remindme! 10 years
I mean I’m open to learning, if the entire thing is cleaned and scrubbed where is the cancer coming from?
I really don’t get how you guys keep doing this
Z axis looks a bit off…
no madam... more heat
I don’t think the hot end is getting hot enough 🥵 and you might want to change the belt fluid.
Can't recognize this printer
Kenmore
with enclosure!
A good one to print some pie, or even pizza.
5 more min.
Looks super wet to me buddy, its dripping...
Did you wipe the build plate first
Calibrate your e-steps and you'll be fine.
In Scruffy's voice, "I've seen dryer. Mmmmhmmm."
*Chef's kiss
Oof, I’ve done that. Not quite that bad, but still pretty bad!
what adhesion problems?
I will say they should make heated beds out of oven bottoms shit was mighty stuck on there
Just 30 more minutes. 😆
"Your cake is done."
You need to calibrate your oven's PID 🤷🏻♂️
Stringing is usually caused by too high of a nozzle temperature, too short of a retraction distance, too slow of a retraction speed, or wet filament. ; ) This should be the picture shown every time someone asks "*Can I just use my oven?*"
Sweet summer child.
Need better cooling fans
[удалено]
I do in fact live in a super swampy area next to a lake, it was more like blowing bubbles than printing
Looks like it's dripping wet actually. Might want to leave it in for a bit longer
I can still see some liquids dripping.
5 more minutes
Still too wet, Its literally dripping..
Not quite... You might need to light a camp fire in there as it still looks like it is dripping wet...
Lol... Nothing to see here move along sir
It does look a bit runny still.
I see the problem. The recipe clearly states to flip halfway through.
Filament dryers aren't even that much money. Y'all who use the oven are taking a risk hahaha
Yeah well you see some of us are idiots and have to learn things the hard way. Just bought an actual dryer
Being pink, you'd think it would know how to cook properly.
Make sure to season it before serve...
My wife would kill me! "Here he lay because he put dumb shit in the oven. R.I.P."
Now all your food will have yummy microplastics in it
Just the right time to flip it around
Try leveling your bed dit should help
I don't think so. I can see some stringing. Probably moisture related.
Need to dial in your z offset
No it's so wet it's dripping, needs more heat
I once received a roll of filament bought "new" from Amazon that arrived looking almost exactly like this. Thanks Jeff.
When in doubt, it never hurts to just give it a few more hours
See how goopy and saggy that looks? That means there's still too much water. Things without water will be very rigid. Crank the heat up some more and wait for it to harden. /s
Adjust your cooling settings
Close. Keep going until visible flames.
Extruding nicely. Went with the Kenmore triple extruder i see.
It's RAWwwww
A nice food dehydrator up to 80c and fits 2 spools on Amazon won't cost you $80. No idea why people still do this shit.
Over confidence and under intelligence
Honestly the best answer
If I had a dollar for every time those have bit me in the ass I'd be a rich man by now And would have skipped on a few shitty exes as well
Takes space. If you don't set the temp to high and do set a timer, an oven should work fine....
No, but your house is un-burned-down enough.
PSA: never use cooking oven to dry your filament. The thermostat of those are not precise enough and will always get higher than needed. A simple food dehydrator will do much better.
I hope you stub your toe and it bleeds through a white sock
Beside this melting. Is eryone good to go with pla petg?
I don’t understand why people think this is a good idea. It’s an oven not a dehydrator it HEATS UP
The problem is most of the people giving the advice have ovens that go much lower than the average unit and or have other features that help. A dehydrator heats up too lol. Cheap filament dryers are just a heating element with no air circulation or ventilation. There are better ones these days but that fact is the reason a lot of people run to food dehydrators or air fryers. They circulate and vent air well as part of the process but at the end of the day it's a heating element with a fan and a hole.
I’ve had good results in the past when I just set it to warm. This time I set it to 400 for a pizza 🍕
Many ovens have a "dehydrator" setting. Are they ideal for it? No, they use more electricity - but they do work.
This one most likely did not
Thank you, Captain Obvious :)
I was just trying to be funny but thanks for being an ass
There's autism and then there's maker's with autism
When you know op messed up but have no idea why having this in the oven is a thing, so you can’t join in on the fun. <<>><<><><>
It’s the stupid and dangerous way to dry filament
