Secondly, if you compare it to the Polymaker PolyBox or even the SUNLU Filament Dryer, the Aibecy eBOX has much lesser functionality and is an underachiever for its price point. From a user's perspective, what characteristics does a good filament dryer need to have (e.g. volume, drying result, etc.)
It also has a humidity sensor and auto drying mode, with a sleek, modern design looks great in any workshop. Their melting point is around 135°C so be sure not to heat them up to that point, or else their Tyvek wrapping will soften and render the whole operation useless.Additionally, this figure not only includes filament spools of the regular 1.75 diameter, but you can also fit in 3 mm filaments as well. This just makes Chefman the best filament dryer in terms of storability. A Drybox is no replacement for a dryer. Drybox just slows_down the intake of moisture, it doesn’t even stop it. AMS is no exception. Some materials (Nylon) need to be printed directly from a dryer, not even drybox is sufficient if humidity is high. I use a Sunlu S2 but I’m on the edge about recommending it. It works great, if you mange it. Personally, I would suggest buying one that can dry at temps up to 70C, however 80C would be best for some nylons and PCs, but 70C is serviceable. Another feature I think is needed is the ability to evacuate the moisture it pulls out of the filament. This is where the Sunlu S2 comes up short. I have to constantly open the lid, or use a small prop to lift the cover by a few mm’s.
Water molecules can also affect the thermal properties of 3D printing filaments. The presence of moisture in the filament can lower the glass transition temperature (Tg) of the material. The lower Tg can make the printed object more susceptible to deformation or distortion at elevated temperatures. Additionally, the presence of moisture in the filament can cause the material to degrade at higher temperatures, leading to reduced thermal stability. Second in this list is the SUNLU Dry Box for 3D printer filament storage, a cheaper option than the EIBOS Filament Dryer Box. This spool holder is compatible with filaments of 1.75 mm, 2.85 mm, and even 3.00 mm comfortably. Desiccant bags work best when they are dry themselves since they do absorb moisture. They can be easily charged using your filament dry boxes or even by using a conventional oven at a low temperature for a few hours. By default, it maintains a temperature of 50℃ and dries for six hours straight. Otherwise, you can always long-press this machine’s left button to adjust the run time.In conclusion, the Chefman’s great performance and immense storability make it a first-rate product for your filament drying needs. It will mostly depend on what your humidity is. The room where my printer and filaments are is pretty humid (50-70%), after the rain or if I clean and forget to open the windows, it gets even higher. Someone with a dry room with 30% humidity might get away with not drying PETG but will still have to take care of PA/Nylon. In short, it does make your prints much better than they were before, but there are a few things that you should know about this dry box. This means you can leave your filaments in the PrintDry PRO overnight and then immediately and directly use your perfectly dried filaments whenever you like.
While standard Sunlu Dry Box is a great budget option for drying a single spool of filament, enthusiasts using multiple materials will want to invest in the S4 when it’s released.The effects of water molecules on different types of filaments can vary depending on the material properties of the filament. Some filaments are more hygroscopic than others, meaning that they are more likely to absorb moisture from the surrounding environment. The impact of moisture on filament properties can also depend on the specific printing conditions, such as temperature and humidity.
He did mention though that the build quality in his opinion wasn’t at the highest level, but still works nonetheless. So for those printing with just PLA or ABS, the single spool Sunlu Dry Box suffices. But makers employing exotic filaments on multiple printers will find the S4’s ample drying capacity and swift moisture removal well worth the added investment. After putting the spool of TPU in the dryer box, it definitely did its job in allowing him to successfully 3D print some awesome models consistently. Since purchasing this product, he hasn’t had any further issues with filament moisture.Automatic Humidity Control FunctionWhen heating is not required, you can activate the humidity mode and freely set the desired humidity level. The system will automatically activate the heating to regulate the internal humidity according to the set value. This ensures that the filament is always ready for printing. printing is a process that creates three-dimensional objects by depositing successive layers of material on top of each other. It is also known as additive manufacturing. The most common materials used in 3D printing are thermoplastic filaments, such as PLA and ABS. Moisture can accumulate in the filament, causing problems during printing, such as warping and poor adhesion. A filament dryer is a device that uses heat and a controlled environment to remove moisture from the filament, ensuring that it is dry and ready for use in 3D printing. This can improve the quality of the final printed object and reduce the likelihood of printing failures. The mechanical strength of the printed object can be reduced if the filament is not dried properly before printing. The drying process can help remove the absorbed water and improve the mechanical properties of the printed object. Various studies have shown that drying the filament before printing can improve the mechanical properties of 3D printed objects made from different filaments.
