Features
- Large-Capacity Independent Dual Chambers:The SH03 filament drying box offers ample storage for 2+2 rolls of 1KG filament (supporting simultaneous loading of up to four 1KG spools). Equipped with independent rotating modules and dedicated filament output tubes, it delivers enhanced drying efficiency for 3D printing filaments. Each chamber features separate temperature control and on/off functionality, enabling concurrent drying and dehumidification of multiple types of consumables (e.g., PLA, ABS, PETG,TPU,ASA,PA,PC).
- 200W + 200W PTC Heating Modules | Maximum Drying Temperature: 185F (85C):The SH03 filament dryer is equipped with dual 200W PTC heating modules, enabling a rapid temperature rise of 50C. With an adjustable temperature range of 4585C, it accommodates diverse filament types.PTC heating elements offer low thermal resistance and high heat exchange efficiency, functioning as self-regulating, energy-saving heaters. Unlike traditional electric heating tubes, they eliminate safety risks such as scalds and fire hazards under all operating conditionsensuring reliable performance during prolonged use.
- Automatic Drying Mode for Enhanced Energy Efficiency:When the SH03 filament dryer is switched to Automatic Drying Mode, the AUTO indicator illuminates. The drying function activates automatically when the internal humidity exceeds the preset threshold. Once the humidity drops below the threshold, the dryer continues operating, and a 30-minute countdown initiates. Upon completion of the countdown, the drying process stops, and the unit enters energy-saving storage mode.
- Temperature Uniformity & Active Dehumidification:Equipped with a 360hot air circulation fan, the SH03 filament dryer ensures consistent temperature distribution throughout the drying chamber. The heating duration is adjustable, with a maximum continuous operation time of 98 hours. Featuring independent air flow channels, the unit automatically controls the dehumidification dampers opening and closing. During the drying process, if the internal temperature exceeds the preset value, the air intake and exhaust vents open automatically to regulate temperature. Effectively preventing overheating and potential damage to 3D printing filaments.
- 4 Comprehensive Protection & Monitoring Functions:The SH03 filament dryer is equipped with four integrated protection and monitoring mechanisms: outlet temperature monitoring, PTC overheat circuit breaker, fan operation monitoring, and main control board temperature monitoringensuring enhanced safety during 3D printing filament drying.
- Touchscreen & Intelligent Control for Intuitive Operation:The SH03 filament dryer is equipped with intelligent temperature control, including a dedicated 50C preset for PLA filamentseffectively preventing softening or deformation of the consumables. It features an integrated segment display (110x68mm, 5-inch) with screen-integrated touch keys and enhanced backlighting for clear visibility. Operation and parameter setup are streamlined: the unit starts instantly upon power-on, and users can quickly configure optimal drying parameters for various 3D printing materials.

I’ve been using a filament dryer box for a while now, and it’s made a noticeable difference in my 3D prints. The whole point of drying filament is removing moisture, and this box does that really well. The unit heats up quickly and maintains a steady temperature, so you don’t have to babysit it. It’s roomy enough to fit several spools at once, which is super convenient if you print with different materials regularly. The build feels solid and the controls are intuitive, so setting the right temperature and time isn’t confusing at all. Since I started using it, I’ve had fewer failed prints, better surface quality, and stronger results with materials like PETG that are especially sensitive to moisture. If you print frequently or keep filament for long periods, this dryer box is a simple addition that really improves reliability and print quality. Highly recommended. I do occasionally have an error when it gets to hot and starts beeping. It turns itself off and doesn’t get hot enough to damage the filament, even when the error occurs with PLA in the dryer.

This is my first filament drier. I was actually surprised at how well the filament and printer behaves with dried filament. I was having problems with bed adhesion and it turns out that dried filament works wonders in that department. the print quality was good when I could get my prints to adhere to the bed but dried filament is a game changer in that department. My prints are higher quality as well. If I would have known what a difference it would make then I'd have gotten this sooner. The drier is good quality and it is super easy to use. You just pop the filament in , turn it on and select the material and it goes about its work. You can change the drying duration and the built in hydrometer readings let you know if you should pop the lid for a second or two to let the moist air out. It does have a breather at the top of the chamber so that isn't really necessary but it was worth a try based on what I read about these driers. I really like this drier and it will be a standard part of my printing workflow from now on. Definitely worth the purchase.-

This tricolor 3D filament blew me away! I used it on my Bambu Lab printer to print the dragon shown in the photo, and the results were nothing short of perfection. The color transitions are smooth, vibrant, and give the model an eye-catching, professional finish that looks like it came straight out of a fantasy movie. Print quality was flawless—no stringing, no clogging, and the layers fused beautifully. The filament fed effortlessly through my printer and produced crisp detail and strong structure, even in more intricate parts of the model. I didn’t have to tweak my settings much at all—this stuff just worked. Highly recommend this filament for anyone looking to add a bold, dynamic look to their prints. It took my dragon from cool to absolutely epic.

This is the best dryer box, for my purposes, that I have been able to find. The lid seals well, it has chambers for desiccant pack, it gets hot enough for PA and ABS, the control panel works well and is logical, and you can feed the filament(s) to your printer through the lid. I only have one small complaint about it (1 star deduction). The ports for feeding the filament through the lid are not angled optimally. The filament needs to take a substantial bend in order to go out the port. And that is true if you are feeding the filament up from the bottom of the spool, or over from the top. That adds resistance to the filament feed, especially with stiff and/or brittle filaments. It's amazing to me that no company has yet designed and produced a perfect dryer. The problems with all of them, like the one I mentioned above, are sooooooo easily fixed. It's not rocket surgery.

I bought this because it was on sale and I never have had the guts to try it. I followed the recomendations for the filament and my printer and this stuff looks great. I dried it in my dryer for 2 hours just because it seemed right even though it came in nice vac sealed packages. I didn't have any problems with clogging or brittleness with the filament. It does print with ease, looks great and you can make many fun projects. I use a Creality K1C with the 0.4 mm nozzle that came with the printer. The only problem I had was I thought I could get away with no glue on the printer plate but I had adhesion problems. Adding glue to the plate fixed that and I never had a problem again.

I found this to replace a different red, blue, green tricolor I have used but was no longer in production, and I searched to find this one and am using it now, because it is SO pretty. I keep getting compliments on items I print with it. It's high quality and comes out smoothly.

Awesome dryer so far! Used this to dry some really old PETG that wasn't printing right and it cleaned up the prints nicely. Eliminated stringing. Also used it to dry some ASA-CF and keep dry while printing the prints came out great, amazing texture. Great value
