Amazingly Simple Free Filament Dryer -You already have one!

[@conorstewart2214]

@@jayblack8132 yes you need a solution for keeping the filament dry. Most common are sealed boxes and desiccant or vacuum bags. However for some filament, especially filament that isn't very hygroscopic, it will take a while to rehydrate, so you can get away with leaving it in the open and only dehydrating when you notice it has become too wet.

[@KitGerrits]

​​@@jayblack8132I am considering the same. Hot air can contain more moisture than cold air and water is more likely to evaporate from something when it is hot, that is how the principle works. In the case of this box (see what I did there?), convection makes the "extra wet air" rise out the top. It is then replaced with colder air, which can contain more air as it heats up. If you cycle the "wet" air out once the drying is complete (and ideally vacuum pack it), the moisture should stay out. I'm too lazy for all that, so I use almost-airtight crates with no vacuum bags and recycle the dessicant pack when I notice the humidity goes up (if it doesn't recover after taking out or putting in a roll). A mini-fridge would be the ideal size for having a mini dehydrator.

[@grlygirl1264]

I did this! I had two failed prints and didn't know why...on one printer the filament (PLA) broke and got stuck in the tube. Not knowing my filament needed to be dried, I moved it over to my second printer and restarted my print. The filament was being shredded going into the extruder (swollen) and broke again. I asked in a social media group what was going on..someone told me to dry my filament. I don't have a dryer so I Googled how to do it without one...and found your video. I gave it a try...and the next day the filament printed flawlessly! Thank you so much!!!!

[@RickyImpey]

Thanks for taking the time to come back and comment👍 I don't really use this method myself as I have a modified filament dryer but I dry all the filament I buy now. So much of it comes with some kind of moisture content. A lot of PETG is unusable from new for me. Like you, I'm always able to print with older filament after a spell of drying too. Glad you have good results after watching one of my videos, that's what they are here for🙂

[@lebasson]

Glad to hear about your results. How long do you keep your filaments in there? I understand that this will depend on how moist the filament has gotten but can you give a ballpark figure of what 'should generally' be enough?

[@thetechhobbyist3d9]

@@lebasson I do about 60deg for at least 4 hours. for my oldest filaments, I did left some overnight so that would be a good 8h. But I do believe that if your filament is in a very bad storage, the humidity can actually break the filament to the point that drying it won't help.

Now that is "thinking within the box".... Excellent, I'm going to give this a whirl - maybe turbo it with an extractor fan, maybe print a cover that fits snug over the spool - you've definitely got my creative juices flowing!

[@florianfeith]

I "built" this yesterday and I was quite amazed how good this works. I had a wet roll of PETG which came very wet from the factory. I couldn't even finish my calibration prints, it was popping all the time and the models just crumbled. Let it sit on the bed at 65C ovenight and it now prints great. I already have 28 of your dryboxes made, so thank you for those also. I use the 5l variant of the storage box because I don't use the somewhat big dehumidifiers but rather silica in Nylon "Organza" Bags. Thanks a lot, you made my life easier!

[@willkiel3137]

Fantastic video. I nearly bought a Sunlu Plus filament dryer as they were only £19 on a well known Chinese site. The cheaper price for it concerned me. I found a cardboard box that the spool fitted in and fortunately it fitted on the heated plate nicely. I did put a few holes in the top. I then realised that by turning the box over would let the hot humid air out and replace it with the room air, (I did this every hour for 6 hours). This is where the air comes from when the hot damp air rises and leaves the box through the holes anyway. The spool stopped the filament touching the plate and dried it out nicely. My prints had got to the stage I was almost going to give up on the Ender 3 S1. Now I love it again. I realised that paper and cardboard won't burn until much higher temps so I used it to keep the heat below the bed trapped in. I'll install insulation under the plate in future. Then I realised that in the software I can turn off the injector head temp to under room temp and the fan to off. So the only power was for the heated bed. I can't find a way to upload the images of the 2 prints, but they are night and day. I had read on the web that PLA doesn't take on much moisture and you don't need to worry about it. PLA needs to be dried out. I nearly bunged my printer, when it was 2 year old filament that had gone damp. I had noticed that it snapped most times I came back to the printer, now hopefully it won't. Now I think I'll get some vacuum bags to store the dried filament in with some silica gel. I don't think PLA will be affected by moisture during a print of 4 or 5 hours, I think it would take days. I'll learn over time.

[@phytosth]

brilliant use of the bed! I came about this in a slightly different fashion that holds a bit more and I can still print while using. I bought a 2 pack of Plant Heating mats on AMZ (in testing stay between 70-85 degrees and each mat holds 2 spools) For < $30 and with 4 cardboard boxes I got a 4 spool dehumidifier that doesn't tie up my printer bed. ;)

[@TheStrokeForge]

what temperature and how much time should I leave my filament on for, if i'm using my printer bed? ? this seems really intuitive!

[@RussG]

That is a clever idea. I would like to add a tip if I may. I punched a little hole in the side of the box so I could insert a digital meat thermometer probe through it so I could measure the air temperature within the box. I did it near the corner of the box so the probe wouldn't hit the filament. I found that it didn't get nearly as hot inside the box as the heat bed on my Prusa i3Mk3s+ and I that I needed to turn the bed temperature setting up quite a bit beyond the desired air temp. I was concerned that I might make the bed so hot as to damage the filament spool or the filament closest to the bed so I didn't turn it up too much. I never got the air temp never as hot as is recommended for drying PETG, but even so, after a few hours of drying time the stringing I was seeing during printing was almost totally gone.

Drying filament worked wonders for me. I live in a tropical environment which means my workshop gets quite humid without air conditioning (75-85% RH at 25-32 degrees C). After fine tuning my printer, filaments straight out of the box print perfectly. I notice around 2-3 days later stringing starts to appear though. It only got worse as cracking and popping start to appear as well. Getting a filament dryer was a lifesaver, though i did regret buying the sunlu dryer later. I had thought of doing what was in this video early on but was too fearful and inexperienced to execute it at the time. But now i have revisited the idea thanks to this. I made a 21x21x10cm cardboard box lined with aluminum foil on the inside, using a combination of packing tape, kapton tape, and double tape adhesive to keep it together. The added height over the normal filament box gives it a bit of clearance overhead, allowing for better convection. Also made a 2cm thick circle with a 9cm diameter out of a strip of cardboard to keep distance between the roll and the bed. Poked holes on top, left some small gaps at the sides where it touches the bed. Heat up to desired temperature, put down the things in order, and leave for a few hours or even overnight. Come back to ready-to-print roll of filament. I still have safety concerns (namely of fire), but so far the benefits seem to outweigh the possible risks. Besides, i have left the bed heated for far longer when doing normal prints. So far? No fires. And i hope it stays that way. Another concern is knocking off the bed levelling, though i think that could be remedied with flatter/harder springs as well as thin silicone pads... which is an upgrade i'm about to do soon.

[@RickyImpey]

Yes, great work. I even dry new filament now as I've seen a weight reduction in every spool I've tried. I wouldn't worry too much about your bed level as long as you have the standard springs compressed to about 1/3 of their original length. That should be plenty to push it back up to the correct position without any problem. Did you see my S1 mod videos? You could make that S1 better than your bed dryer and print at the same time....kzbin.info/www/bejne/a5umh4dmob1-r7c

Isn't 70° C pretty hot for a test if you're drying PLA? PLA gets soft and sticky at the usual 60° temperature used while printing. Wouldn't it be best to set the temperature to 50° in that case? That's what I'm using now to attempt to dry a spool of PVA, but I don't know how effective it would be. I'm concerned about the filament fusing or annealing to the spool if I make it hotter. Letting it sit for a day with the heat bed set at 50°C seems to work OK. I encountered one difficulty when the Prusa MK3S "safety timer" kicked in and shut down the heat bed after half an hour. You have to send the g-code "M86 S0" to disable the safety timer. You can put this in a .gcode file on the SD card and simply run it from the printer.

[@Sembazuru]

I use a food dehydrator (the type with the door on the front and wire-racks for what you are dehydrating). I usually run it at 45°C for PLA with good results. I think I need to use your drying foam technique to benchmark it's performance to satisfy my curiosity.

[@norm401]

Great idea and I'm sure it works if you have wet filament. Better yet never let your filament get wet! My environment is typically minimum of 45% to 60% humid. But I never have a problem because I use those air/watertight totes with desiccant after each use of any filament. In totes the humidity averages 27% to 30% and the desiccant shows no signs of wearing out for over a year. And the big benefit is no wasted energy or wearing out of my heated bed.

[@TDOBrandano]

Just store the spools in hardware shop paint buckets with desiccant packets. the paint buckets are air tight by definition, and each can store 3 to 4 spools. the desiccant can be dried on the print bed the same way as the filament.

Good use for that old unused 3D printer on the floor of the closet. The point about flammability is certainly valid. Maybe something like a garage sale bundt pan would be a better choice.

Thanks, thats so smart Ill try it out

[@clarkkent5442]

Thank you SO MUCH!!! I was about to buy some very expensive equipment, or stuff my PETG into the oven before I saw this. Since I have an old Ender 3 I rarely ever use anymore, this has just become my drying station!!! Thanks SO MUCH!!! I'm surprised this hasn't been taken down yet, I know there's going to be a lot of very rich people that are very pissed off if this info takes off within the 3D hobbyist community lol

How many hours for PETG?

[@ishimarumakot0]

Thinking about using a simple aluminium baking pan instead of using cardboard, do you agree? Amazing video, 2 years later and still delivering

[@davidg5898]

Brilliant. I'll definitely be trying this soon.

the way that works the best for me is even simpler, i placed a space heater (or how it calls) beside the 3d printer in a way that it blows warm air on the filament before it goes in the extruder. the only thing is to make sure it blows only on the section between the filament spool and the extruder so it doesnt make a mess. no need to predry, no need fancy amazon driers, it dry the hell out of the filament seconds before it get extruded. im living in a extremely humid country (70% at day time and 100% at night) and it works better than anything i tried.

This is one of the coolest ( or hottest?! ) hacks ! ✌ This will be my go-to solution till I buy a filament dryer or build one of my own.

Great use for the old small bed of my Tevo Tarantula. Since the day I replaced it with a bigger one, it has been lying around useless. Now I know it was waiting for this revelation 😅

[@parsar.8653]

what would be the ideal temperature for PETG and PLA? (fastest drying without making the filament stick together if that makes sense)

[@Tome4kkkk]

What an awesome idea, backed with actual measurements! What would be the Bambu Lab A1 75 deg bed power draw? I used a smart socket and it showed me 800-1000 W (!) during heat up and then 250-350 W later on. The problem is that Chinese smart socket doesn't offer a current power draw graph, only a discrete value refreshed every 4 seconds or so.

I just lined the inside of a filament box with aluminum foil tape. First time to try it out 🙏🤞
