This is the most german channel in the world! All those charts, measurements and data gathering is awesome!! Thanks very much
dome dom all except the state of the nozzle! For God's sake Stefan clean your nozzle, you're triggering my ocd 😂
And I think Stefan's MK2 used to have a silicone sock. That Kapton tape patch in the middle of the print bed also triggers my OCD. Is it still there? ;)
Nope, finally changed my PEI quite a while back ;-)
Sorry, that was after a dirty print. Usually I try to keep my nozzles clean ;-)
Lol people
I spent 3 days trying to fix my printer then I realized the filament was moist. I switched filaments and it worked great again.
You "released" or you "realised"? :)
Oh good catch. I updated it.
Did u ever dry out the moist roll??
@@elfpimp1 moist....
@@SangheiliSpecOp lol...
Watched your infill pattern/percentage strength video, and now this one. It is great to see not just advice, but practical experimentation to demonstrate the suitability of that advice. Thank you for taking the time to log your results, plotting them in a meaningful way, and then sharing them with us.
This is so brilliant! It’s always so easy to over look the little things when tackling tough projects but this video shows just how important seemingly small details, such as drying filament, can have such a huge impact on a final product. Thanks so much for posting this video and doing all of this research!!!
Good to see this covered for a material like PETG. I store even PLA in dry boxes when possible and it helps with quality.
Another truly informative and useful video from a channel that has become essential viewing for those of us designing and printing functional parts. As a bonus, the beautifully done videography, video editing, and graphics make the videos a pleasure to watch.
Thanks mate!
Thanks for doing this testing. I always thought that my PETG had moisture in it. Now I definitely know I do, and how to correct it. Your videos are really well done and the research you put into them is superb. Thanks again!
Thank you so much for taking the time to add proper subtitles and not relying on auto generated
This worked so well for me! I did a modification like how you did for yours and I'm surprised it really worked! Did about 8 or 9 hours of dehydrating and my prints are looking significantly better! I thought I'd have to throw out my material and buy new ones, so I'm so glad I came across this video. Thank you!
Thank You for another Super Excellent video. It is so nice to see stuff from someone who has such a knowledgeable and methodical approach!
Was getting ready to throw out a roll of ABS, saw the exact issues you spelled out: stringing, snapping sounds, steam, bubbling.
Roasted it for 12 hours just below GT, tired again, perfection!
Pacific Northwest tends to have high humidity, worse in the winter.
Only one roll of PLA [bronze, metal filled] has ever needed roasting right from the factory.
Everything now stored in individual freezer-bags; each roll with its own desiccant pack, roast the desiccant packs every month to keep them active.
I'd like to see the same tests with PLA.
Me too.
Me too! I almost exclusively print PLA and have had no troubles so far, but now my printer is in a basement that might be somewhat more humid than my room. Girlfriend complained about the noise.
I got my first 3D printer about 11 months ago. Prints came out beautifully, and I was quite happy. I was using PLA. All winter, with low humidity, I just left the spools out when convenient, and in one-gallon zip lock bags otherwise. As spring came and the humidity went up, I started getting problems similar to the ones shown here. It took me a while to figure out what was happening (remember this was my 1st 3D printer!)
me too!
Me too. Mostly the influence on annealing, shrinkage and mechanical properties, before and after annealing
I paused the video to compute how much energy it would take to dry my filament. Later I resumed your video and realized you computed it for us. you really think of everything when you make these videos!
Thank you for this great channel! I watch Angus and Joel as well, and they make great videos, but your scientific approach really adds value, and as I design mostly functional parts, the tests you perform are very useful. Danke sehr!
Very helpful video, drying the filament in the oven is def the way to go. Your idea of boxing up the filament roll during a print is pretty clever, I like that idea👌I store my filament in large ziplock vaccum bags, they are usually sold for storing clothes
This is so freaking informative. Thanks for the extreme thoroughness. I'm going to take drying my filament a lot more seriously now.
AWESOME VIDEO! You have made me a believer in my printer again. I was just about to give up because of the excessive stringing which I could not program out. Now I know it is the filament.
This is really useful information, haven't even bought my first 3D printer yet, but I'll certainly make sure to store the filament as dry as possible.
I can never find a bad video made by this guy. Awesome stuff, always! Thanks for posting, your channel encouraged me to buy my first 3D printer!
ahh...that crispy sound that tells you its time to try your filament! Excellent vid/info!
Excellent video! I'm certainly going to review my filament storage arrangements as a result.
Fantastic structured video. With a lot of factual information. Thank you kindly for your advice.
Again an awesome vid mate, as always , love your work !
Very good. Thank you for producing such accurate tests. This lot of information is very important for someone living at the beach, where humidity is a problem - and worse than that, having just bought a new 3d printer. Out of the box, some PLA+ that I bought about a week ago just started clicking with moisture. I went desperate.
I truly appreciate your scientific approach and your succinct explanations. You provide a great service with excellent information.
Bartgalok Hulugu Agreed- this video is a graduate level thesis for a phd
Thanks for another great video. Now I'll do a test print with a few filaments I have, after I "bake" them a bit, since they normally "pop" a bit when printing.
Impressive. Thank you for doing this!
PLA is my only filament right now, so I'd love to see the same tests on them! Thanks for the convincing! Ordering a Dehydrator.
Under appreciated you tuber! So glad I found you! Keep up the great work!!
Thanks for your hard work. Great tests.
Dang! This is the most thorough video I have ever seen lol. Well done, and thank you!!
This is most incredible channel i ever seen! Thanks for your shares.
Interesting project 👍
Thanks for sharing 😀👍
Awesome, as always,... Thank you.
Very nice and informative. Not too wordy and no ego. Thanks so much.
I don't have lot experienc in 3d printing. So small details like dry filaments can cause me tons of head pain) like i got spool of filament printed some models, and then keep it for some time. After i back after few month and try to print by the same spool it is became wicked, and i got thru cycle of temperature rising, leveling, extruder adjustments, even nozle cleaning, and all this measures worked somehow for +- stable prints. And after i saw this video i realised problem ) and why my spool became unstable. Thanks for sharing knowledge, and really nice experiments.
Thank for this video, it's good to see the results of some tests. I've had similar issues with the hot and humid summer we've had. I ended up building a storage drawer for my filament that is fed dry air from the internal parts of a food dehydrator that is controlled by a Raspberry pi with temp & humidity sensors. It has helped.
That sounds a bit over-engineered 😉
CNC Kitchen you are probably right! But we all need projects to keep us busy. This drying drawer is installed in an old half-height server rack that I have. Ultimately my printer will be inside that rack as well and I will be able to control temperature and humidity within its enclosure to. Is it necessary? Probably not. But I had most of the parts sitting around already anyway. :)
This truly was very helpful! Thanks!
Subbed - if this sorts my filament issues, you sir.. are a gentleman.
Would love to see a video similar to this, comparing the effect of moisture on different types of common filament. pla, petg, abs, asa, etc.
Danke für die ganzen diagramme ^^ wie immer supper arbeit!
This is great info.As a VERY new 3D printing nerd, I had no idea. I will store my filament in a bin with that absorbent stuff.
Good stuff! I suspect this may be part of my current printing issue, but severe bed and self adhesion issues didn't seem to be solely from moisture issues.
You have the best videos. Thanks
pro tip: "crystal" cat litter is the cheapest and most widely available source to get a lot of silicagel. just fill old socks or so with it. before using it as a dessicant, it needs to be dried in the oven or microwave, though. holding a spoon over it, and looking for condensation, is a great indicator to see if it's actually dry.
(the cat litter comes partially saturated, so it doesnt stick to a cat's slightly damp paw pads. cats despise sticky things.)
PS: if you arent in a hurry, a few days near a heater, in an airtight bag with plenty of dessicant, revives most soggy spools.
Thank you so much! This was exactly my problem!
Good analysis. Thank you.
I guess I'm going to have to start looking for a food dehydrator or 2 in the thrift shops. Thanks!
Very useful, thank you
Hey Stefan, I also noticed humidity affects the surface finish of PLA a massive amount especially when "ironing" a top flat surface. In the summertime where humidity can reach 60%+ in my place the surface finish from "ironing" is very poor. In the wintertime where humidity is currently 34% in my place the surface finish from "ironing" comes out great. Do you have any data on controlling the storage environment of PLA to improve the surface finish for "ironing"?
Very helpful, thank you!
Please do one of these analyses on ABS. There are many in the 3d printing community who believe that somehow only nylon and PC absorb moisture and ABS is immune - prove them wrong!
ABS certainly does absorb moisture, but it does not undergo hydrolysis.
I would like to see the same tests on ABS and PLA.
@@KoochDawg hydrolysis will affect the material itself, but any wet material will get bubbles.
I can prove this right now. New abs spool I bought 1.5 year ago is currently bubbling in my CR10
Very informative vid!
top notch video as always.
Nice vid Stefan
I have a moist PETG, i dried it for 5 hours @ 55C and didnt change that much
I am now going to dry it at 65C
When building a home made dryer, it makes sense to have an area that is heated for the spools and an unheated area for the desiccant. Desiccants take up water much better when cool. You can relay on hot air rising to take the air from the heater up past the spools. When the air reaches the lid, it will cool and want to sink back down. If your desiccant is off to one side and in racks, the cooler air will fall past it. A wall with a gap at the top and bottom can keep the falling cool air away from the rising warm air.
I have built a thing like this for a different purpose and it worked well.
“Hands… up! Which of you has not been storing your filament correctly?”
Great video, excellent editing, nice humour and a great message! Thank you.
Nice testing!
great work thx
A maker can get a cheap dehydrator and for extra $20 a tp-link smart plug switch. Now set that knob to the temp (60C for PLA) and set the smart plug to run 6h. In Florida in a garage, PLA gets wet in days. My first run with wet PLA, I did not realize that it can clog the hotend. I ended up replacing part after part. Till I figured it only happened with PLA that was out for a couple of weeks and never with new spool. Dehydrator was the key for perfect prints,
Thank you very much!
I keep all the filament stored at 32 Degrees Celsius all the time (dry room). Since I do this I had 0 trouble. TPU, PLA, ABS, PETG, etc.
Good job, as always! You should have more subs!!
Very nice and thoroughly rigorous scientific method video.
Great video, very very well explained. Sub well earned. Very interesting and helpful. Thank you Brother
I like to use a vacuum chamber (it's just an aluminium stock pot) and a hot plate...just space the spools off the bottom of the chamber with insulation and let everything heat soak up to around 150f, then pull vacuum for an hour or two. It comes out nice and dry
Thanks, useful info
I always store my pla in a big plastic bag with a couple of silica gel packets between prints. Works fine
Great video! Although for the testing with filament that has the most moisture, it would've been helpful if the filament experienced the more realistic conditions of being left in room air over the course of a humid summer or two, rather than being left in a plastic bag with a moist towel (because nobody does the thing with a moist towel). There might be a significant difference in water concentration in the filament and how far the water is penetrated into the filament.
Danke für die Info! ^^
Great work 😙
I live on A RiverLess city without a sea near, But i still have that problem
gonna try it
I just bought my first 3d printer and learned the hard way. I destroyed the extruder by running a print all night and not knowing the filament was moist. $80 later for a new extruder. Thanks for this video. I’ll be making a humidifier box for my filaments
Another $80 later: "...uh, I meant de-humidifier box..."
Very nice video, thank you. How about freeze drying the filament?
I find the way 3d printed parts break extremely interesting as they break in a very different way to anything else
25 watt dehumidifier on amazon $20
100 quart storage bin at local big box store $10
25 watt reptile or seedling heating pad on amazon $10
silica gel indicator on amazon $15
It won't dry your filament in a few hours. But I keep all my rolls in that $55 bin and they get dry in a week or two. I don't burn thru filament like crazy, I could see needing a specialized box that only fits one roll if I imminently needed dry filament. Silica gel helps in case the power goes out and you haven't emptied the dehu tank and it's nice to not have to recharge the beads in the microwave so often.
Man this is exactly what is happening to me. Time to get drying!
yea my oven runs on gas so it is tons more humid than electric. So I got a dehydrator for my filament. Toaster ovens I have found do not go low enough for the cheap models while a cheap dehydrator has control in the range that filaments are dried at.
Very informative and useful video thanks ! i am a new sub.
Bro, u r awesome. did u make any videos on filament making?
Sehr informativ, prima...:-)
...mit Zug- und Kerbschlagversuch.. nicht schlecht

Good day, Stefan.
I am starting in 3D printing and would like to start on the good foot.
Your video was quite instructive and I would plan to purchase a dehydrator to dry me PLA filament spools at first and then, store them in a dry environment like you did. Except that at the moment, I have something like 17 spools (all the main colors (black, red, green, blue, yellow, orange, purple, grey and white), and all metallic (sliver, copper, bronze and silver) not forgetting silky colors (red, green and blue .. for now ! LOL) and neon yellow too ! I'm missing the transparent ones (red, green and blue), but it won't be long. I think I'll need lots of containers .. unless you have an idea for me.
For the time being, I store them if their original box with silica gel pouches (5g x 4) and I'm afraid that it won't be enough to keep them dry, since I like in Canada (Québec) where it's mostly humid and, the boxes, being cardboard, will transmit humidity to the filament. However, I bought « reusable » desiccant. Will this be enough to keep them dry ? Ambiant humidity level, is around 50% in the winter, and 70% in the summer.
Thank you for your suggestion and your time commenting on my intentions. Have a great day and happy continuation. I like your Channel.
I guess you could say this video took 2 years to make (including the filament incubation hahaha) amaziingg :D
Mine is stored in my shed outside always cold wet air. The prints are decent. I have the ikea enclosure. I print ABS
Hi @CNCKITCHEN, great video! Would you please suggest acceptable humidity levels PLA and PETG should be safe to be stored/ exposed to?
Great test. I would be interested in the same test with abs and pc because this materials should have more issues with moisture. It would be very interesting which time will be needed till the material becomes wet view minutes, hours, days, weeks,...
I plan on putting a dehumidifier in my workshop room. Wonder if I should rig an option to divert the exhaust into the print enclosure and spool storage area.
I've only ever dehydrated TPU before printing. A couple hours in the oven at 160ºF makes a huge difference, but after watching the video, I may go much longer next time, as well as try it out on other materials. I had a hell of a time getting print parameters for PETG to print a watertight container, and I never did get it 100%. Maybe drying out the filament first would help!
Could you do tests about mechanical creep among different materials?
muy bueno, creo qe esto podria resolver las fallas de muchas marcas de filamentos, y de seguro muchas criticas a marcas de filamento fueron incorrectas por el factor "humedad". Excelente trabajo! saludos desde Argentina, Dios te bendiga :D
Excellent.
Another well done informative video..thank you.. just want to add that the colored dessicant are toxic inside the blue one mostly i heard stuff like wash hands after touching the orange.. there are the white ones that supposed to be better but with no indication on moisture
Thank you very much :)
Sou brasileiro, falo pouco o inglês, mesmo assim aprendi muito com esse canal. Obrigado !
Great job on this video. I am very happy to give you a thumbs up. Have you thought about storing your filament under a vacuum to keep the levels of moisture very low?
There is a solution for that on Kickstarter I guess but the normal silica gel desiccant works very well for me.
I'm thinking about building a dehydrator on the buildplate of my printer. Some isolation, add walls and the temperature sets itself
Outstanding work! Thank you so much. Have you thought about using a dehumidifier in the room? That may be what I'll have to do in my basement.
basements are generally a bad place to print because of the cold atmosphere unless you have enclosures for your printers
Thanks @@joshklapperich9416, I have an enclosure for the first one, but not yet for the second one-I'll have to build one. More than temperature, though, my concern is humidity, and the effect it can have on filament.
hi
nice video helpful I'm new to this 3d printing stuff and have a question about filament storage i keep my filament is vacuum bag with desiccant and humidity monitor
my room temp is like 21 to 22 C is this a good temp for storage or should i increase temp
Just a pro tip regarding those round food dehydrators: You don't necessarily need to cut up the trays that come with the machine. I discovered that you can use a single tray on the bottom and then put a 3.5 or 5 gallon bucket on top of it. Drill four 3/8" (9.5mm) on the bottom of the bucket for air to escape. Works perfectly. This lets me keep the other trays clean so I can use them for drying food. I recommend putting a thermometer of some kind inside of it because the numbers on the dial do not correspond well with actual temperature. Also, it's possible to over-dry a resin. This is more of a problem with Nylon. Over-drying results in increased viscosity, which can cause its own problems during printing. You usually want to shoot for three to four hours at between 50C-116C depending on the specific resin. If you're unsure of what temp to use, literally google the resin type with the words "drying temperature" after it. You can also hold the temperature at about 30-35C indefinitely without any detrimental effects. This won't actually dry the filament if it is moist, but if the filament is already dry, it will maintain it.
