- Storage vacuum bags are popular in kitchen use, but some of them can be used to store filaments to protect them from the moisture or to save the aroma inside (for scented filaments). They can be used with manual pump but with some 3D printed adapter (shown in video), you can use vacuum cleaner too.
On Banggood it is sold as vacuum bag for filament storage:

Thank you for making this video! I ordered some of these zip-lock type bags with a small USB rechargeable vacuum pump from AliExpress, and of course, there were no instructions. After struggling with the bags for a little while, I was beginning to wonder whether or not there was some sort of check valve, or if the adhesive layer on the "hole" needed to be peeled back and replaced. Your video made it clear on how to use the kit. Thanks again!
Thank you for this tutorial. It answered some questions that I could not find the solutions to elsewhere!
Thank you very much for the review of these bags. You actually answered some questions for me.
Thank you very much for providing the .stl file. You rock!!!!
This was helpful - thank you!
Not all heroes wear capes, my friend.
awesome topic, easily overlooked. i have so many of these bags i collect lol
Me: trying to look at this random video to get an idea how those pump/valve work since somehow my other pump do nothing with those bags.
Igor: Give dimension of the pump.
Well, nice!
i had 10 of those bags from esun, but only one of them worked. on the other ones the air just couldn't be sucket out, whether with the pump nor with the vacuum cleaner. the solution was to heat up the valves. i did this with suckung out the air just over the outlet of the hot air of the vacuum cleaner
I also use this method, for me it works great.
There are now sets of bags with USB vacuum pumps that have become inexpensive online. With these bags and printing from a dryer box, I have been able to not waste filaments. I saved enough old spools of moisture soaked material for the dryer and bags to pay for themselves.
Hi Thanks for the video I bough some sous vide bags seem the same and going to place a silkica gel small bag inside too :)
Excellent instructional video, they seem to be much better than the bags I'm have.
I bought Space Saver brand ones, but these seem better.
@@dinosoarskill17 A google search for Vacuum Bags including any other arrangement of words gave countless results mostly for food sealing bags that I gave up looking. Thank you for the brand name I was able to go directly to their site.
@@Laystraight No problem! Feels good to have helped someone. They have a lifetime warranty on the bags, if there's a leak. But I have never tried to claim on it
Thank you, thank you.
enjoying the videos, keep it up
Glad you like them! Thanks.
Thanks!
Thank you Jim! I am glad that you find the video useful. If I may suggest another one, with better bag quality: th-cam.com/video/O7p_8GZ_RLM/w-d-xo.html
I always want to design and print something like the converter. If I were you, I will try hard to calibrate the printer instead of redesign the converter. You have already used the caliper to measure the pipe size which is accurate.
I agree. This is new printer, and in review I noticed it underextrudes the TPU a little bit. PLA is OK. But their user interface is too simplified, there is no estep calibration in UI (like on Ender3v2).
how does vacuum sealing filament in hygroscopic material prevent moisture? does it just slow it down? i was thinking of making an vacuum sealed acrylic enclosure, but learned acrylic is also hygroscopic so am wondering what the actual benefits are.
It slows it way down. There's three steps to this: the vacuum lowers the boiling point of water so whatever moisture in there has more chance to become vapor and get extracted while pulling a vacuum, there is less air in there so there is less total moisture that can seep from the air back into the filament, as well as the vacuum slowing down the absorption rate into the filament.
You're right that eventually moisture will be sucked into the bag material and end up in the bag over time, but if you dried your filament and then stick it in a vacuum bag there is just another barrier for the filament to just absorb all that moisture back, so it will stay dry for longer.
Thanks for this video i was also planning to purchase this vaccum bags 🤘🏻😃
For how long does the bag hold the vaccum ?
good question
If they don't leak after 2-3 days, they hold vacuum several months. Approx 20% of my attempts I have to reseal again after few days. It's very important to use that plastic correctly I mention in video.
I purchased the Esun version of the bags, look very similar. Mine have held vacuum for several months with out any real loss. They also came with a moisture indicator you can put in the bag. I did find you have to press the vacuum circle down and make sure it’s sealed closed after vacuuming.

@@Laystraight I got mine on Amazon.
There is an idiom in Turkish; “The way of the mind is one.”
I just got some cheap version of this off amazon.. it don't work at all and I've tried 5 different bags.
These bags are awefull. I ordered 10 of them and after testing 5 I had 4 of them fail. Maybe I got unlucky but they are very fragile. How did your held up after 1 use?
Mine works great. Few times air goes out, but then I used that plastic part for better sealing and then they hold the vacuum.
I use vaccum bags from stores. Nowadays there are a lot of places you can find them and they come ready for a vacuum cleaner. As well are cheaper (like 2-3 euro for 3 of them).
In time though they all leaks air. No idea if the design nor they pop or whatever. May be yours are better in that way
I'm thinking using vacuum bags hurts more than it helps if you are using some kind of moisture absorbing material (For example silica) inside the bag. If the filament has absorbed some moisture I'm thinking it would be a good thing for it to be surrounded by dry air that it can transfer it's moisture to. When using a vacuum bag I imagen this transfer of moisture between the filament and the silica will be hindered.
Silica packs can’t dry filament. They keep it dry by scavenging water in the air/vacuum in the bag.
Water adsorbs strongly on the surface of the filament and heat is required to drive it off. Vacuum alone doesn’t pull the water off fast enough to be practical.
Getting the moisture away from the filament speeds drying. Vacuum does that, but so does pumping in dry air. If I’m in a hurry to speed up drying in my Sunlu drier box I’ll stick the straw of a canned air duster through the hole in the drier’s top and give it a few blasts. The gas in the can is bone dry and has higher density than air, so the moisture gets pushed out.
@@KEO7890I still can't see why it's beneficial to use a vacuum bag. The vacuum is not strong enough to lower the boiling temperature of the water inside the filament to any meaningful degree. All you end up doing is hindering the dry air from circulating inside the bag, and trapping moisture.
@@sumguje5917.. if you leave it out without a vacuum bag, it will continuously absorb water. In the vacuum bag it’s protected from the environment where it can’t absorb anything else.
Steve, you are not getting my point.. I think it would be more effektive to put the fillament in a loose plastic bag versus a vaccum bag because the loose bag will allow moisture to be transfered to the silica beads more easily. The vaccum creates a tight seal around the entire roll of fillament making it hard for moisture furtest away from the silica having a tough time getting absorbed
@@sumguje5917 in my case my city's moisture level never drops below 60% so I literally can't find any air thats more dry than filaments. Because of that filaments can't give moisture naturally and any air will fuck up silica beads in a day so they have loose the ability to suck more moisture (from the air that you planned to make drier than filament so filament gives his moisture to the air). those bags not a solution to moist filaments its a loosers league prize that you cannot get them drier you just want them not to suck more moisture. If your citys air is more dry than mine yeah yours would be bettter because air is not the enemy water is...
I bought some. Some bags worked and others didn't. I can't recommend this solution personally.
I bought one of these kits but the pump isn't doing anything :(
Are you sure? Close the end of pump with your finger, then try to pull back the holder. If no vacuum below your finger, try to send it back or ask for refund..
Yep, same for me. no suction at all. ESUN said "damaged in shipping" but I cannot see how that's possible. Offered me a AU$10 refund. Looks like ill be buying TPU and making the part for the vacuum!
I use a food vacuum bag device
I tried the PrimaCreator Air Tight Filament Storage Set and its damn awful product.. Stay away and choose something else...
Kullanışsız tavsiye etmiyorum. This version is useless i dont reccomended.
I agree, quality variates. You could try these ones: th-cam.com/video/O7p_8GZ_RLM/w-d-xo.html
@@MyTechFun no i didnt. But im watching thank you.
