A few users have actually tested the temperatures that are displayed on the dryer box and they say it’s accurate. The ease of use is one of the main reasons why so many users love this machine. Using a filament dryer can also help remove moisture from the filament before printing. By controlling the moisture content of filaments, it is possible to produce high-quality 3D printed objects with improved mechanical, thermal, and electrical properties. 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.
More expensive than other options. But, it’s the best filament drying box around – you get what you pay for.What people have really admired about this dryer is how it’s able to store and dry filaments for long print jobs, making them fit for prolonged usage. PLA doesn’t need a dry box to 3D print but using one can help produce optimal surface quality. PLA is known to be hygroscopic which means to absorb moisture from the environment. When PLA or filament has absorbed moisture, it can get brittle and even lead to print failures, as well as blobs/zits on your prints. However, one of the most apparent downsides to this filament dryer is that it is only able to store one filament spool at once. As compared to other dryers, this comes off as a significant con.
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. 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.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. 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.） Rather than use an oven for this Nylon which can be troublesome and not temperature-accurate, he put the spool of Nylon in the filament dryer for 12 hours at 70°C (the maximum temperature) using the useful timer feature, and it completely dried the filament like it was a new spool. The hygroscopicity of 3D printing filaments can be affected by various factors, including the chemical structure of the material, temperature, humidity, and storage conditions. The chemical structure of materials used in filaments can impact their hygroscopicity, with materials containing polar functional groups being more hygroscopic. Temperature can affect the ability of materials to absorb moisture from the air, while higher humidity levels result in a greater concentration of water vapor in the air and can increase the amount of moisture absorbed by the filament. Proper storage conditions, such as storing filaments in a sealed container with a desiccant or in a dry environment, can reduce the amount of moisture absorbed by the filament. 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.
Other than all that, using a desiccant to dry your filament is a common standard nowadays. If you think it meets your needs, be sure to get it. If not, opt for a full-fledged dry box. ABS (Acrylonitrile Butadiene Styrene): ABS is a thermoplastic polymer that is widely used in 3D printing. It is moderately hygroscopic and can absorb moisture from the surrounding environment. The presence of moisture in the filament can cause warping and deformation during printing, leading to poor dimensional accuracy. Drying the filament before printing can improve the dimensional accuracy of the printed object. 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. 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.Water molecules play a crucial role in hygroscopicity and diffusion. When a hygroscopic material is exposed to water vapor in the air, water molecules can be absorbed into the material through diffusion. Diffusion occurs because water molecules tend to move from areas of high concentration to areas of low concentration until an equilibrium is reached. The rate of diffusion is influenced by temperature, humidity, and the concentration gradient between the material and the surrounding air. Materials with polar functional groups are more likely to attract water molecules and are therefore more hygroscopic. 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. Compared with the mainstream filament dryers currently on the 3D printing market, we believe that Polyphemus is leading in terms of functionality. 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.
Here is a brief comparison of the effects of water molecules on some commonly used 3D printing filaments: 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. 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. 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.Another thing to add is that there’s no humidity sensor to tell how much moisture is present inside the dehydrator. 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. The SUNLU Dry Box aims to maintain a constant temperature and prevents excessive heating that could potentially damage the filament. 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. Another user has pointed out that they would prefer a manual on/off button on the Dry Box since the current way of doing that demands a few too many presses from you.
