Creality Official Filament Dryer Box 2.0, 360° Hot-air Circulates Heating with Fan, Upgraded Filament Dehydrator Storage Box for 1.75/2.85mm PLA PETG ABS TPU Material

Read several reviews on 3D printer review sites about filament dryers and this one is consistently top rated. I was having loads of trouble printing PETG that was more than a month old, and this completely resolved my issues. I run it for about 10 hours before printing, and my filament is printing perfectly again. I leave it attached to my printed with the included PTFE tubing. The filament unspools easily and feeds nicely into the printer. Also great for keeping dust and debris off the filament. Easy to use, just big enough to hold the filament without taking up loads of space. Only complaint is that the rear opening lid means you quite a bit of space behind the dryer to load filament, and if you have it on a shelf it could be difficult to get the filament over top. Only complaint is that there is not a stopper for the tubing so over time it will creep down into the dryer and cause some feeding issues. A dab of hot glue around the PTFE tube where it is inserted into the dryer will prevent this issue.

I’m a product designer and engineer focused on overland van gear, and I’ve run just about every kind of filament through my printers. The Creality Hyper PLA-CF is hands down the best carbon fiber PLA I’ve used so far. It prints super clean, even at high speeds, with sharp detail and a nice matte finish. The stiffness and surface quality make it perfect for functional prototypes and final-use parts like mounts, brackets, and custom panels. It’s easy to print, feeds reliably, and holds its shape well with no warping or clogging — just make sure you're using a hardened nozzle. It is a bit brittle, so I wouldn't use it where there's a lot of flex, but for rigid, lightweight components, it’s a winner. I’d definitely like to try other Creality specialty filaments after this — but so far, this one’s a solid go-to for anything I need to look good and hold up in real-world van builds.

Really nice basic filament dryer. I love its compact size and easy to use interface - just a single knob to select drying temperature and time. It does the job well and without any fuss. This dryer has a built-in humidity gauge that seems very accurate - I use it to judge when my filament is "done" and all my prints after I use this dryer have extruded perfectly. My only compaint is the blower fan is powerful but small so it is pretty loud and operates at a pitch that I find rather annoying. I wish they used a different fan or implemented a system to quiet it down a bit.

Im surprised. It prints really well and is a very good quality. Came untangled. Performs great

Rule number one of FDM printing: dry your filament. Want strong adhesion, smoother walls, and fewer “why did this fail 17 hours into a 22-hour print” meltdowns? Then keep your plastic spaghetti from soaking up the humidity like a paper towel at a water balloon fight. Does drying guarantee a perfect print every time? Nope. But it dramatically boosts your odds and keeps you from rage-quitting halfway through a spool. This Creality Dryer Box does exactly what it says without drama. Toss your rolls in, set the temp and time, and walk away. I don’t even touch filament fresh out of the packaging anymore—24 hours in the box first, minimum. Too many manufacturers (especially bargain-bin brands) ship filament wetter than a Florida summer. The box itself? Quiet, reliable, and you can feed filament straight into the printer while it’s cooking. Controls are idiot-proof, price is reasonable, and it works whether you’re a seasoned maker or still trying to remember which side of the bed-leveling knob to turn. Bottom line: If you don’t own a dryer box, you’re not printing—you’re gambling. And this one’s a solid bet.

I have a larger filament dryer and I needed one that could be much more compact and sit between my printer and the clutter I have around my office. This fit perfectly and allows me to dry and print at the same time if needed. Something like this is a must have for some of those really tricky expensive filaments like PAHT-CF. The build quality seems to be holding up as I would expect and the price for the single spool version doesn't hit your wallet like some others. This was able to help improve my print quality on anything that likes to just suck moisture out of the air. Really enjoying having this by my printer.

8/30 update: So in addition to the problems that I've experienced with this product below, now is a brand new reason to hate this product and brand: This unit, purchased in May, just a few months ago, has now completely stopped functioning. It will turn on, start drying the filament for all of about 30 seconds, and then shut off. Long story short, it's now just a paperweight. I can promise one thing: After my experience with this product AND with Creality's customer service, I will never purchase from this company again. To be clear, I would rather light my money on fire than let it get into the hands of Creality. EDIT: Creality contacted me because they were concerned about my poor review. After some back and forth, they informed me that the "solution" to my problem was that I am supposed to purchase a teflon tube (NOT included with my dryer) to insert within the plug in the lid in order to make the dryer feed the filament properly. In other words, they appear to be acknowledging that their product is defective, but rather than FIX the problem, they would rather make their customers buy additional supplies to fix it themselves. To be clear, I am not opposed to making modifications to a product myself to make it work better or make it more useful. What I am opposed to is a company being aware that their product has a flaw and intentionally putting it on the customers to fix it. For that reason, I am downgrading my review to ONE star. I will absolutely never do any business with Creality again. ----------------------------------------------------------------- So... you're supposed to be able to do two things with this dyer box: 1. Dry and dehumidify a filament spool. 2. Feed the spool from the dryer box to your printer. This unit so far appears to do the first. Completely fails at the second. The lid has a small plug that you can open up that you're supposed to feed your filament through and then run it your printer. The problem is that this rubber plug is so tight that my printer (Anycubic Kobra) can't properly pull the filament through. My print head and the dryer box wind up playing tug-of-war with the filament, with the printer pulling the box over and then ultimately throwing an error because the filament has jammed. The only solution I can think of is to drill a wider opening in the dryer box so the filament more smoothly can pull though, but I'm not even certain this will work because the rollers on the bottom of the box don't really roll, so the spool isn't really able to properly roll. Even so, if I have to drill a bigger hole in the lid so the filament feeds properly, that kind of defeats the purpose of the dryer box in the first place. Basically, I now have a dryer box that can properly dry out my filament roll so I can remove it from the box and properly mount it on my printer for small print jobs, but I can't continually use the dryer box to maintain correct humidity of a spool for larger prints. Since this only actually performs half of the job it's supposed to, I'm giving it two stars.
