Sovol SH01 Filament Dryer and Dehydrator - 3D Printer Spool Holder and Dry Box for PLA, PETG, TPU, ABS - Compatible With 1.75mm, 2.85mm Filament

Humidity is blocked inside the box as there are no vents and the holes on top to pass the filament are not practical as the printer could not pull the string out of the box

I've been looking at various filament dryers for quite a while (including on Aliexpress) and this seems to be the best thing going for what you get.There are several less expensive dryer boxes that will dry one roll at a time, but this is the only one that I've seen that will do two at a time (or one really large roll).Unlike most of the others, this unit also has a seal that the lid sits in, clasps to hold the lid closed, an internal fan, and shows the humidity (not just temperature).I have seen people modify other dryers to add some of these features, but after the trouble and cost of the modifications those boxes still only hold one roll at a time. This is still more economical than buying two un-modified single roll dryers.This dryer preforms quite well and has brought some life back into some of my older rolls of filament. Since this has a proper seal it will also keep a roll dry even when it's done. I now have a muti-filament (3) 3D printer and I have ordered a second dryer so I can keep three rolls plus a spare dry all the time while printing.You can set 3 different temperatures (40C, 45C, & 50C) and drying time from 6 to 12 hours. The box heats well and seems quite stable, and you can really only hear the fan when the lid is open (will update if it gets noisy). There are touch sensors for the three buttons on the front, and the backlit display is very legible. The external power supply gets warm but not hot and I've had it running for days without any issues so far.It has two filament holes on the top of the lid, with seals, and a seal for the power plug on the back. The only thing that would have been nice is extra filament holes on the back (or front) for alternative routing options.I'm quite happy so far and would recommend this over the single roll dryers (even if you only really need it for one roll at a time)5 star product 🌟🌟🌟🌟🌟

Chegou com 5 dias de antecedência em relação à data de entrega estimada, me surpreendeu positivamente.Gostei muito do produto. Deferente de outros já adquiridos foi usado assim que saiu da caixa, preparado 2 rolos de filamento para impressão.Recomendo como o melhor custo beneficio que encontrei na Internet, principalmente para quem tem sistema multifilamento sem aquecimento como eu.

I recently purchased the Sovol SH01 Filament Dryer to address moisture issues affecting my 3D printing projects. This device has proven to be indispensable in maintaining filament quality and ensuring consistent print results.✔️ Key Benefits:Effective Moisture Removal: The Sovol SH01 excels at eliminating moisture from filament spools, preventing common issues like stringing, bubbling, and poor layer adhesion caused by damp filament.User-Friendly Interface: The dryer features an intuitive control panel, allowing me to easily set the desired temperature and drying time based on the filament type.Versatile Compatibility: With adjustable temperature settings, it accommodates various filament materials, including PLA, ABS, PETG, and more, ensuring optimal drying conditions for each type.Continuous Drying Function: The option for continuous drying is particularly useful for extended printing sessions, keeping the filament in optimal condition throughout the process.❌ Areas for Improvement:Size Considerations: While the dryer accommodates standard filament spools comfortably, larger or wider spools may not fit as easily. It's advisable to check the dimensions before purchasing.💡 Final Thoughts:The Sovol SH01 Filament Dryer has become an essential part of my 3D printing setup. By effectively removing moisture from filaments, it ensures smoother printing experiences and higher-quality results. Despite minor size limitations, its performance and ease of use make it a worthwhile investment for any serious 3D printing enthusiast.✔ Best For: 3D printing users seeking to improve print quality by maintaining dry filament.❌ Not Ideal For: Those using non-standard or oversized filament spools without verifying compatibility.👉 Overall: 5/5 – A must-have tool for achieving consistent and high-quality 3D prints.

The Sovol SH01 dual filament dryer is a great addition to any 3D printing setup, especially if you're working with multiple printers or moisture-sensitive materials. I previously used a Sunlu S1 dryer, which did the job, but after adding a second printer to my setup, I wanted a solution that could keep up. While a dual dryer isn’t strictly necessary if you primarily print PLA, it becomes very helpful if you regularly print with materials like PETG or TPU—as I do—especially when printing on both machines simultaneously.One of the most surprising things about the SH01 is how quiet it is. I’ve seen a number of reviews claiming it’s loud, but that hasn’t been my experience at all. It’s quieter than both of my printers and significantly quieter than my old Sunlu dryer. There's a faint fan noise, but it's comparable to a laptop fan at idle—barely noticeable.In terms of features, Sovol packed a lot of thoughtful touches into this unit. It includes built-in roller bearings for smooth filament feeding, a hygrometer to monitor humidity levels, and a simple control interface with temperature and timer settings. Compared to the Sunlu (which has fewer controls), the Sovol is more user-friendly when it comes to dialing in your desired settings.The polycarbonate cover has four filament feed openings—two on top for direct drive setups and two on the front for Bowden-style printers. These openings are necessary to let moisture escape and bring humidity down effectively. They come with gasket covers, though I find them more optional than essential. I usually leave them open during use and close them in between to help maintain low humidity levels.It does take a bit of time to heat up—expect around 20 minutes to reach 50°C due to the slightly larger internal volume. But for longer drying sessions (6+ hours), that warm-up time is negligible. In my own testing, I saw the relative humidity drop from 30% to 23% in the first hour and below 20% after about 8 hours.If I had one small request, it would be an additional front opening that allows for quick access—something that doesn’t require threading filament through it. Sometimes I start a print with filament in the dryer, then move it to a printer-mounted spool mid-print, and a quick-access opening would make that easier. It’s a minor inconvenience and likely irrelevant for most dual-dryer users, but worth noting.Final Verdict:The Sovol SH01 is a quiet, efficient, and well-designed filament dryer—especially great for setups using multiple materials or printers. It outperforms my Sunlu S1 in both usability and performance, and I’d definitely recommend it to anyone looking to level up their print quality.

Es una buena herramienta para mantener tus impresions con la mejor calidad possible. Por el mismo precio te puedes comprar un de una marca mas reconocida como SUNLU per a diferencia de esos es que este seca dos rollos al mismo tiempo y aparte tiene sello y ventilador para un secado uniforme. Altamente recomendable si impremes mucho con PETG o ABS, filamentos que aborben mucha humedad.
