“I brought a bunch of these bags for filament storage, but I hate the manual pump because it takes too long and too many pumps and brought an electric pump ( https://a.co/d/03k0ViIE ), but it doesn't do anything. What kind of electric pump works with…”
“I designed this tray for my dehydrator once I got my N4 Max. I just tweaked the design to strengthen it as mine are functional but a bit flimsy. Printed in PETG clear with .6 nozzle although one was printed on QIDI Plus 4 with .4 nozzle (3rd tray from bottom). I was going to share the model but didn't see an attach file button. https://preview.redd.it/5nqvqbbw7nvh1.jpg?width=1576&format=pjpg&auto=webp&s=6a9035fd1852a7704c86c1090962b14b043776d3 https://preview.redd.it/j4d8nuxh8nvh”
“I was about to buy an old air fryer off Facebook Marketplace to dry filament that had a recommended drying temperature of 90°C -- outside the temperature range of just about every filament dryer except the Sunlu E2 (though only just outside the range of some "high temp" dryers). What stopped me was realizing that the only thing separating the filament spool from the heating element was just an air gap of a few inches. If the fryer gor accidentally bumped, I could see a possibility that”
“Creality filament dryer 2.0 - USD 50 Esun Ebox lite - USD 63.5 Creality space dryer - Polymaker Polydryer - USD 90 These are the only heated dryer options available to me locally. Any recommendations on what I should go to? Obviously Polydryer should be good but its pricey for me. Any reason I should consider Ebox lite or creality dyer 2.0 as viable options too? Any redditors who have used them; would love to know your experience and the pros and cons? PS: I know going for a diy setup from print”
“Currently I have an ams1 and have printed desiccant chambers and have filled them with activated alumina. Stays around 30% rh which shows a D rating on the Bambu handy app. I store my filament in a watertight 58qt storage container with alumina that did stay at a lower rh for a while but is staying around the 30% mark. Would it be wise to purchase a filament dryer and dry the filament rolls and then put them back into the AMs and storage container? Would that help to sustain lower rh levels in t”
“I am looking for something that can dry ASA-GF/Cf, Nylon/Cf, and to recharge desiccant. I was looking at the West3d Toaster oven, but that's like a 2 month wait. The Sunlu e2 is pricey. I saw some blast ovens on Ali express, would blast ovens make good filament dryers? submitted by /u/Odd-Flower-1861 [link] [comments]”
“I spent weeks on end on a wild goose chase, trying to fix my Lulzbot Taz Workhorse’s extrusion failures only to find out that the problem was that the filament was the problem. It had been exposed to humidity too long. There was a lot of filament left so disposing of it wasn’t a pleasant experience. Amongst the many AI conversations I had in troubleshooting, one suggested that I dry the filament in a conventional oven. Would that really work or is it just a hallucination? submitted by  ”
“i just watched a video on CNC kitchen that explained how very dry filament can actually absorb water from silica gel packets and i was thinking if anyone here tried using anhydrous calcium chloride, anhydrous magnesium sulfate or sodium hydroxide to dry filaments before? or are these compounds not too hygroscopic? submitted by /u/Dorceless_ah [link] [comments]”

“Forgive my ignorance. It's been suggested I buy a filament dryer. If I "dry" the filament and then put back on spool holder wont it just get "wet" again? Do I have to dry between every print? submitted by /u/Unique-Abalone [link] [comments]”
“I’m looking for a wall-mounted filament holder for multiple spools and I want to keep it as simple and economical as possible. I’m open to 3D-printed designs, but also MDF or plywood solutions . If you know of a design that can be made from leftover pieces of MDF/plywood and cut at home, I’d be very interested. For the spool axle, I’m planning to use PVC or aluminum tubing , possibly as a double-spool holder, so I’d prefer a design that doesn’t require much 3D-printed material. I’m not looking f”

Seems like you'd have to fix the PTFE tube on both ends else pushing would just flop it around. Need my second hand inside the machine to squeeze the cutter, so can't just hold the tube with one hand while pushing through. Do you need the PTFE tube at all, for PLA and PETG?

“I m making my own 3D filament dryer and I was wondering how much silica gel I need to dry a spool of PLA (1kg 1.75mm) rn I just added 1g bc that's what I have but I was wondering how much I needed for it to actually make a change as my spool has been in sitting on the printer's spool holder thingy that isn't closed for about 1½ months and I don't know how wet it is or if it's wet at all submitted by /u/No-Variety9081 [link] [comments]”
“So despite having a dehumidifier in my work area, my PLA is showing signs of moisture. I have been putting the 250-gram spools in gallon plastic bags with silica gel packs, and that works well for them. I currently don't have anything for the bigger spools. I was thinking of putting them in a cooler with a home store moisture eliminator inside. I'm interested to hear what anyone else has rigged up. submitted by /u/yoyoingdadjoke [link] [comments]”

“I've been trying to think of a way to store my filament better, currently pla sits on a rack that is built into my stand, open if I've used it and anything else goes into a tote with decadent in it. I print straight from my Sunlu s4 usually but I'm just trying to think a bit more. I kept seeing posts about using wine fridges for storage and it hit me, I currently have 2 extra mini fridges, but one is the larger style like you'd see in a college dorm. What if I put a safe dehumidi”
“Hi all, I store my dried filament in Vacuum bags when not in use and don't have any issues with the bags themselves, the pumps to get the air out on the other hand are absolute **** has anyone got a recommendation for a powered pump that works well and doesn't take an age to empty a bag? Preferably one I can get in the UK. submitted by /u/Ok_Battle_7852 [link] [comments]”
“. . . and remember you have no less than (2) Nesco dehydrators (dirty but functional) in storage. A round AND a square one. Time to get cleaning! Is there a good time/temp guide I can refer to for drying in one? Tips? I hear to leave the lower tray intact for airflow. And I think I will invest in a good mechanical timer as well. submitted by /u/09Klr650 [link] [comments]”
“Basically title. I have a food dehydrator, and the trays have gone missing. I still have the lid, though. There is no temperature gauge or dials; it's literally plug it in and rotate the trays for X number of hours until the food is dehydrated to your liking. I have a laser thermometer and am wondering if it would be viable to use it as a filament drier. Thoughts? https://preview.redd.it/g2xd6ksrssnh1.png?width=471&format=png&auto=webp&s=e9ad8a85dedf0637b5853a26c0f4d7d603a3d952 &”
“TL;DR: small nylon mesh bags. I researched a bunch of different solutions for using and drying desiccant and thought others might be interested in what I came up with. I originally planned to print some desiccant containers once I found one that fit my storage containers (there are a lot of different models posted online). Eventually I came up with an off-the-shelf solution that I think works better than any printable container I found. I use small (6.7" x 5.5" = 17cm x 14cm) nylon mes”
“Based on recommendations from this subreddit, I bought a Septree dehydrator a couple of years ago for drying nylon. Two years later, I'm finally getting around to printing with nylon. . . . The problem is, the dehydrator only goes up to 190F or 87.77777C. I'd like to get it over 90C. Apparently they have "professional" model dehydrators that go up to 195F but I only bought a "consumer" model that's capped at 190F. Because +5F is totally going to melt the whole thi”
“So last night I was getting ready to print something and I noticed that my 2 unopened rolls filament were no longer vacuumed sealed tight which told me that they've been exposed to the air this whole time somehow (there's no openings as far as I can see) so I placed one in my SUNLU dehydrator for 10 hours and then started a primt After the print was done I tried to remove it off the bed and the whole thing crumpled in my hands. I'm passed the return window for Amazon what else can I”
“I was going to make a diy filament dryer and I was wondering if I need to have fresh air come inside chamber or let some air out in the process or can I just make a fully closed chamber with air circulation inside submitted by /u/Aradtaromchi [link] [comments]”
“For Nylon (PA) and TPU I keep filament in an Ikea Samla dry box, since they can pick up moisture again pretty quickly. The small silica gel packs never got the humidity down much, so I tried some larger room moisture absorber packs I found on sale at a supermarket (I still have an unopened one, see the second pic). A few months later (to my surprise) there was some liquid on a spool, I then noticed the moisture absorber pack leaked onto the spool. I assumed the granules were silica gel, but afte”
“Due to a lot of peoples recommendations I upgraded from the comgrow sh01 to the sovol sh02 but literally the first day I used it it threw an error. It’s been a week or so since and it’s seems to be working fine but I’m planning on returning it anyway. I’m just wondering if I should get another unit or something like a creality space pi or sunlu dryer. I just want something that works reliably and lasts a long time. I basically only print PLA and PETG at the moment but would like to use other mat”
“Hi all, I am looking to buy a filament dryer and between looking on Amazon and searching for "dryer" on this subreddit I am a bit overwhelmed. AFAIK, I look on the Wiki what filament I use (PLA, PETG and maybe in the future TPU) and take the max temperature of this table and make sure whatever dryer I buy reaches that temp? Is there anything more to it? A cursory glance at the Amazon listings gives me a price range from ±35 to Sunlu E2. Any recommendations what to look out for before p”
“how do yall dry your dessicant? just looking for a good way to do it since i cannot use the oven or microwave, and the only other method i tried was the printing bed. the dessicant didnt last long for that though. I have a filament dryer (creality single spool) and was told i could use that, but i fear that the rollers might cause any containers put in there to spin and break something, since i cannot print anything temp resistant (i only have petg). would it be better to just keep buying new on”

“i live in a very humid place, and i was looking for solutions for storing my filament. This one i don't have but seems a smart solution. I have like a mini portable fridge that i don't use tho, and maybe with some silica gel it could do the job. Also i know i can't really use it as a dryer, so if anyone knows a good 30-ish euro dryer i would appreciate submitted by /u/Kind-Temperature-136 [link] [comments]”
“I tried using my microwave but the moisture just puddled at the bottom of the plastic container. I was wondering if an air fryer works, cuz it sort of evaporates the moisture? I don’t think it would be efficient to run my oven for 2-3 hrs either submitted by /u/Sabrinalover711 [link] [comments]”
