3D Printer Filament Dryer Box - 4L Compatible with 0.5/1KG Filament - PLA PETG TPU ABS Material

Excellent functions and great a reducing moisture in filament

Great little dryer have 2

I'm not ready to spend a lot on this new hobby of mine, so I bought two of these and set them up. The humidity has consistently stayed around 18-25% for both of them. I wanted to know if this meant they were good, so I bought an identical hydrometer to sit outside of the boxes. That has consistently shown around 55% humidity in the room. I wasn't convinced this wasn't just a lucky reading due to the cheapness of the hydrometers, so I swapped one of the internal ones with the external one and I was pleased to see the internal and external readings quickly returned to the previous readings. So these are undeniably keeping my filaments dry compared to leaving them open to the room. They're not perfect though: if you use the top exit point for your tube, then the bottom one is left open. Maybe this isn't an issue, but it seemed daft to me to have a box that is designed to form a seal when snapped shut, and then have a hole in the side of it, so I sealed it up with some hot glue on each box. Also, I have seen the issue that others have reported, where the tubing magically migrates itself inside the box, because of the one-way nature of the little teeth at the exit point. That seems like a design oversight - albeit nothing that can't be mitigated, I'm sure. Lastly, I had the same issue as nearly everyone else: the supplier clearly tries to stick the hydrometer to the inside of the box instead of just giving us the double-sided tape to do it ourselves. A poor decision because, it seems, they always fall off the box and stick - permanently - to the paper instruction sheet instead, ruining the tape. I rescued the fragments of tape that I could and distributed it around the edges of the hydrometer displays. I like the fact that these don't need power. Just some fresh desiccant from time to time (but I've no idea when, yet).

Hydrometer was stuck to the instruction manual and wouldn't come off without ripping manual and now I need to provide some kind of adhesive to stick it to box.

The seals aren't great so the desiccat beads fill up with water very quickly. The mounts to hold the shaft the spools sits on are not deep enough so it doesn't sit properly and the humidity and temp sensors falls off pretty much straight away. Better off just using a filament dryer.

I bought this as a cheap stopgap to keep my filament dry when connected to my Bambu a1 mini, but it's so good I've not bothered to replace it. It's cheap and cheerful which is exactly what it advertises itself to be, pop the top off, put filament in, feed through the included tube and it's completely sealed off from outside moisture. The only issue I found was I had to stick the temperature sensor back to the side as it'd come loose in shipping, but that's no big deal. I won't knock points off this product for this, but I did find that if you have filament that varies in width throughout the spool it can sometimes get too hard to pull through for the printer and in the case of mine pause printing with an error about stuck filament, so be aware and use a good brand (or just take the lid and tube off if you need a quick fix).

If you’re into 3D printing, a filament dryer box is such a game-changer! I got one recently, and it’s been a lifesaver for dealing with moisture issues. No more weird prints or brittle filament breaking mid-job. The box keeps my filament dry and ready to go, which is especially important if you’re working with hygroscopic materials like PLA+ or Nylon. If you’re serious about 3D printing, this is totally worth the investment. It’s saved me so much time and frustration already! 👌

Yes it's a simply sealed box, but there's some nice machined parts to this. Would 100% recommend

Verarbeitung ist nicht so gut Aufhängungen der Spulenrolle sind nicht in gleicher Höhe montiert, funktioniert gerade noch richtig!

Cumple lo que se indica en la publicación, funciona a la perfección

Rewritten: I recently purchased the Kingroon Filament Dry Box to protect my 3D printing filaments from moisture, and I have to say, this product has exceeded my expectations in terms of value and ease of use. One of the standout features of this product is the buckle design that allows me to lock the cover tight and keep external moisture out. The box comes equipped with rubber seal strips that work effectively to isolate any moisture that may be present in my workspace. The desiccants are placed inside the box to absorb any moisture that may have already made its way into my filament spools, ensuring that they stay dry. The LCD display is another great feature of this product, as it displays the real-time temperature and humidity inside the box, making it easy to monitor and adjust as necessary. The two couplers included with the box allow me to fit different filament feeding directions on different 3D printers, which adds to the versatility of the product. The aluminum spool holder inside the box is sturdy and reliable, supporting the filament spool and keeping it in place while drying or printing. The product is also very easy to use, with a simple setup that doesn't require any special skills or knowledge. Overall, I am very pleased with my purchase of this dry box. It's an affordable and effective solution that offers excellent value for its price. The ease of use and reliability of this product make it a must-have for anyone looking to protect their filament from moisture and ensure the best possible print quality. I highly recommend this product to all 3D printing enthusiasts. There are DIY options on Printables and Thingiverse that work the same way but once you source parts and spend the time printing, this is a much easier option.

Sirve muy bien y es útil en temporadas de lluvia, quedé satisfecho con el producto

Does the job, quite affordable for the value if you aren't prepared to DIY your own. One notable flaw is the Bowden coupler - it's push-to-connect and pointed for easy install from outside. Unfortunately, this also means that during printing, the tube isn't locked in position and the filament tension can pull the tube into the box rather than pull filament out; this will eventually cause a jam if not attended to. Not hard to prevent with a wrap of tape to keep the tube from pushing further in, but slightly better design (i.e. an interior nut with a tube stop) would have avoided the issue.
