Helps keep my filament that wee bit more durable as it fully dries it out even if there is only a small amount of moisture. Heats up quick. Helps printing quality and finish to be more successful. Fab price too Review: Great for getting the fillament dry - I must say I am very pleased with this product. It came well packaged, runs on 24V adapter which was supplied. You can set the temperature from 35-55°C, and set the baking timer from 1h to 24H. It achieves the 55°C in about 15min which is quite fast, to be honest. Nice big backlight LCD gets the temperature reading a breeze. Controlling the dryer is easy. Just set the temperature with the buttons and hold 3 sec to set the time. I had one spool of PLA which had been absorbed moisture and popping whilst printing, gave it 6h of drying on 55°C and no more popping, print came out great. The great thing about it that spool is laying on two rotating cylinders (they seem to be ball bearing) so you can print whilst drying, so you have dual-purpose, drying and spool holder at the same time. There is an additional hole on the top I suppose you could install the pneumatic PTFE connector but you can use the bottom hole for ease of use, which does not let too much hot air out anyway. There is no fan inside which is great because is dead silent. Front and back of the dryer get fairly hot to touch, I reckon where the heater elements are but nothing too severe, thinking about it, good that it has two heating elements because you will have even distribution of temperature inside the chamber. Overall this dryer looks very good, I am really happy with how it performs and will continue to use it to get my 3D prints as good as they can be. ## Features - HOT-AIR CIRCULATION HEATING SYSTEM: Applying hot air circulation heating which makes the temperesuture inside box more even, filament dryer box aims at drying the wet or brittle 3D printer filament - Personalized Temperature Setting: The maximum temperature can be set to 55°C and the drying time can be set to 99 h. 2-inch LCD screen, real-time display of drying temperature and humidity. - Filament Dryer and Remove Moisture: SUNLU 3d printer filament dryer box is designed to keep filament dry and remove moisture from kinds of filaments.

Your best bet would be to put it into a oven at about 6o to 70C for 8 hrs. Then you could use the box to keep it dry when you are printing that works for me. **Q: How do you work out humidity?** A: With pla it will be brittle and snap easily if it’s dry it will just bend **Q: Can anyone tell me the maximum width of a spool that this can hold? Or if a Prusament spool will fit inside?** A: The max size is the width of a 1kg spool, atleast thests the biggest I've put into it and that's quite snug ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price *by J***. on 19 May 2026* Love this item.

You put the filament inside, turn it on, it heats up. A small fan circulates the air for more even heating. The manual is very sparse and doesn't really match what the buttons are actually doing. The QR code link to the full manual is broken. With a little experimentation I figured out how to use it (you have to hold the buttons to enter settings), but needless to say a manual that actually matches the product would be nice. One fundamental problem with how the device works is that there is no way for moist air to escape. You have to open and close it every 1-2 hours during operation to exchange the air. Otherwise you will just have hot moist air inside. I was still able to dry my PLA filament and achieved a noticeable decrease in stringing, so it does work. I'm only deducting 1 star for the downsides because the device is very cheap after all. ## Frequently Bought Together - SUNLU Official Filament Dryer S1 Plus, Built-in Circulation Fan, Filament Dryer Box Storage Box for 3D Printer Filament 1.75 2.85 3.00, S1 Plus White - SUNLU PLA 3D Printer Filament PLA Filament 1.75mm, Neatly Wound 3D Printing Filament, Dimensional Accuracy +/- 0.02 mm, Fit Most FDM 3D Printer, 1kg Spool (2.2lbs), Good for Lithophane, White - Dry & Dry [2 LBS] Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) - Reusable Desiccant Beads Silica Beads(Blue to Pink) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/712222798-sunlu-filament-dryer-s1-plus-3d-filament-dryer-box-pla](https://www.desertcart.tn/products/712222798-sunlu-filament-dryer-s1-plus-3d-filament-dryer-box-pla) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-25*
