Compared with the mainstream filament dryers currently on the 3D printing market, we believe that Polyphemus is leading in terms of functionality. He previously tried other filament dryer boxes, but didn’t get results as good as with this one. An old 2-year spool of Nylon was giving him issues because it wasn’t sealed properly in a bag. Nylon: Nylon is a synthetic thermoplastic material that is known for its strength and durability. It is highly hygroscopic and can absorb moisture from the surrounding environment. The presence of moisture in the filament can cause issues such as warping, deformation, and reduced mechanical properties. Drying the filament before printing can improve the mechanical properties of the printed object. 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 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.

As it is designed particularly for the purpose of filament drying, there are a number of extra features that make it stand out as compared to other such products. It really does depend on the quality of your filament and how much moisture has been absorbed, but having a dry box can be helpful but not needed. Moisture can be dried out of filament quite easily. More expensive than other options. But, it’s the best filament drying box around – you get what you pay for. The PrintDry PRO holds up to 4 spools of 3D printing filament at once, and even has adjustable temperature controls which make it especially ideal for PLA and ABS users.If you’re really on a budget, or simply have no real use for the added features of commercial filament dryers, then your best option is standard vacuum seal bags. If you’ve bought your own filament recently, it more than likely came vacuum sealed. PLA (Polylactic Acid): PLA is a biodegradable thermoplastic polymer that is derived from renewable resources such as corn starch or sugarcane. It is less hygroscopic than ABS and is less prone to absorbing moisture. However, the presence of moisture in the filament can still cause issues such as poor adhesion between layers and clogging of the printer nozzle. It also has a humidity sensor and auto drying mode, with a sleek, modern design looks great in any workshop.

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. 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.Most 3D printing filaments are hygroscopic, meaning that they absorb airborne moisture over time. If this happens, they will become unusable or even unstable. It’s not enough to think that your workspace is dry, as a lot of that moisture is undetectable to us. 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. A desiccant screams filament drying on a budget. It’s obviously the cheapest entry on the list, and works for maintaining the moisture levels of your filament without absorbing more afterwards. 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.

Filament dryer and filament storagePolyphemus is designed for convenience, featuring an adjustable exhaust vent on the lid. Closing the vent when heating is unnecessary allows control of internal humidity and temperature, preventing excessive drying.The device also includes a dedicated compartment for desiccants, which absorb moisture from the air, ensuring a dry filament environment. Regular replacement of desiccants based on their lifespan is recommended.Thee spacious chamber, multiple heater fans, and compatibility with various materials make the S4 perfect for those constantly switching filaments across multiple printers. The presence of water molecules in 3D printing filaments can significantly impact their mechanical, thermal, and electrical properties. Moisture can cause the filament to absorb water and therefore swell, leading to shrinkage and warping during the printing process that can reduce the dimensional accuracy of the printed object. The presence of moisture can also cause bubbles or voids to form in the printed object, which can weaken its mechanical properties.

The top of the dehydrator has a digital display where you can control the temperature and time. The timer goes up to 19.5 hours while the temperature ranges from 35°C to 70°C. At the same price, is a single spool filament dryer or a multi spool filament dryer is more suitable for you in your usage scenarios?（We are talking about ‘unit price’ here, one spool slot is recorded as 1 unit price.） 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.It’s dust-proof, sealed properly, and has enough space for 4 rolls of 0.5KG filaments, 2 rolls of 1KG filaments, or 1 roll of 3KG filament. There is even a built-in fan to circulate the hot air inside the whole dryer box, improving the moisture removal. filament spool compatibleAfter installing the 3KG expansion part, Polyphemus expands from its original 210mm diameter to accommodate a larger 250mm diameter. This increase in size allows for the capacity to hold up to 3kg of filament. For one, not only does this Dry Box store and dry your filament spool whenever needed but because of two built-in holes that allow seamless extrusion, you can 3D print with your drying filament too.
