Vacbird 3D Printer Accessories Upgrade Vacuum Kit, 20pcs 3D Filament Vacuum Bags with USB Pump (30 * 34cm) Reusable, for 3D Printer Filament Storage, Protect Filament from Moisture

Nice simple little filiment bags and sealer. The pump comes with a usb a & c so you can even run it from your phone. The bags are a nice size and easily fit a 1kg reel in. Not a tight squeeze like some others and the pump is simple to use just put I over the blue disk and press the button. I found the easiest way was to make sure it's on a flat surface. The bags are well made and not just a cheap freezer bag with a valve. Would highly recommend it as a inexpensive but excellent way to keep your reels in good health

I was in the process of getting a two reel drier when I tripped over this product The bags are substantial and easy to seal and the vacuum pump is well designed and effective Now, I only need a one reel drier and keep dried filament in these bags All in all, this is an excellent product in that it is simple, inexpensive and effective

Pretty good so far, better than the manual pump. Worked with my existing bags. Supplied bags although take a 1Kg spool, its very tight to get in.

Completely useless. Followed the instructions carefully with several items and they all leaked out completely in less than 24hrs

Actually super impressed. I've ordered a couple of different vacuum bags for filament in the past, and these feel just as good as more expensive ones. Good seal, good size, and feel pretty durable. The vacuum pump is also surprisingly nice. USB-A or USB-C, so can plug into basically any usb charger you'll have. Nice braided cable, and just generally feels nicer / more premium than what you'd expect for the price. Took about 10-15s to get a really good "vacuum". Packaging is nice too. Overall very impressed, so much so that I was compelled to write a review.

The 20 bags I ordered arrived in 2 bags with 10 vacuum bags in each. I have opened 1 bag & so far I have tried to seal 7 reels of filament but 3 of the bags will not seal. The vacuum bags that work do work well but the other 3 had a slow leak.

I wish I had come across these before because they would have probably saved me some rolls of filament and some time, cleaning out an AMS when it broke from being so brittle. My new regimen is drying and then sealing in one of these bags with a desiccant bag inside. Should have probably done it a long time ago! The pump is a bit fiddly to get used to, but the more you do it, the better you get at getting it in the right position, although I think I have one bag that is a bit dodgy. But I have more than enough for now.

Pleasantly surprised with this. Watching their video, didn't think it would suck that much, but I think they're demonstrating incorrect fitting or something in the video, cause once you get it right, it sucks the air out pretty quick (obviously get as much out as you can first!). The great thing about these is that the valve is flat, virtually unnoticeable, unlike some others with a massive plastic cap - so they fit nicely back in the filament boxes (they always seem tight fit so I didn't want big plastic valves) Some people seem to have trouble getting the 'seal' right, but I haven't had a problem. Just put 3 fingers either side of it underneath, and you can hear the sound change. The pump is very nice too - has a USB-C adapter built in to it, and nice finish, nice cable, and nice fancy rubber cable tie. Bags seem very good too. I have some filament sealed up for a week now, not noticed any leakages.

Para filamentos higrófilos estas bolsas de vacío ayudan pero no son la panacea. Yo suelo meter un higrómetro baratillo en la bolsa (además de bolsas de sílice) y realmente se crea una diferencia con la humedad ambiente pero ni de lejos es un vacío total. Creo que para materiales algo sensibles a la humedad, como PETG o TPU, son interesantes, pero para otros más sensibles (que además suelen ser caros) mejor buscar otro sistema o combinarlo con un secador de filamento. Si te estás planteando si merece la pena pagar los aproximadamente 10€ de diferencia que hay por tener una bomba automática en vez de la manual de otros kits, sólo puedo decir que tu brazo lo agradecerá. Muchísimo. Y además probablemente la uses más. Aunque igual prefieres ahorrarte la diferencia y de paso muscularte. En serio, viniendo de una bomba manual y sin que esta sea perfecta, la mejora es inmensa. Con la versión manual es fácil acabar dejando fuera el filamento por la pereza de darle a la mancha hasta que se te caiga el brazo, mientras que con esta en un par de minutos lo tienes al vacío. Digo que no es perfecta porque a veces me cuesta un poco conseguir el sellado para que haga el vacío y acabo mirando la bolsa un par de minutos como un tonto decidiendo si se está encogiendo o no. Girar un poco la bomba sobre la válvula cuando empiezas a hacer el vacío parece ayudar. Por cierto, son una bomba y bolsas típicas de vacío, no tienen nada específico para bobinas de filamento a parte de ser bolsas del tamaño más o menos adecuado (tirando a grandes), y se puede usar perfectamente con otras bolsas que usen ese mismo tipo de válvula plana.

Buenas bolsas para filamento, al principio cuesta un poco coger la dinámica de vacío, pero luego lo conserva muy bien y lo mejor, es que es reutilizable.

Alors clairement j'ai failli tout renvoyer ! Après premier test, impossible de faire le vide, la doc est très sommaire et jamais utilisé ces systèmes, lisant quelques commentaires j'en ai déduis que ça ne marchait pas. Puis en lisant d'autre commentaires j'ai quand même cherché et vu des vidéos youtubes : il faut bien mettre a plat la valve, c'est pas intuitif, mais ça a fonctionné ! Et la une fois le coup de main pris c'est tout bonnement génial ! 15 sacs de fait et toujours impeccablement sous vide après une semaine, c'est TOP !! Il faudrait par contre faire un tuto vidéo officiel je pense Vacbird. Je reprendrais ces sacs les yeux fermés.

Veel eerder moeten kopen, het doet zijn werk naar behoren op een gemakkelijke manier

Fonctionne super bien
