Just be ready to take some time to learn the unintuitive LCD controls. But with handy presets for different filaments, it’s easy to get great results once you get the hang of it. eSun eBox 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. Moreover, its transparent viewing window makes it easy to monitor what’s happening on the inside while the dehydrator does its thing. 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. It also has a humidity sensor and auto drying mode, with a sleek, modern design looks great in any workshop.
Here is a brief comparison of the effects of water molecules on some commonly used 3D printing filaments: 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. 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.
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. Compared with the mainstream filament dryers currently on the 3D printing market, we believe that Polyphemus is leading in terms of functionality. 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 best way to use the PrintDry PRO is as a storage container as well as a dryer. It’s designed so the filament can be fed directly from the dryer to your 3D printer, eliminating the risk of further exposure between removal and printing.
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. 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. 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. It includes 9 adjustable trays that can be easily removed from the inside. This creates a lot of space inside the dehydrator, allowing one to store multiple spools of filament inside. It has rollers and bearings within the platform so you can 3D print while your filament is drying. Another ideal feature that similar products are missing is the surplus of holes where you can insert your PTFE tube so it can be mounted in many positions.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. 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.
The SUNLU Dry Box aims to maintain a constant temperature and prevents excessive heating that could potentially damage the filament. 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. 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. Many popular materials used in 3D printing, such as PLA and ABS, are hygroscopic, meaning they can absorb moisture from the atmosphere. Moisture in the filament can cause the filament to become brittle and difficult to work with and can cause problems during the extrusion process. When the filament is heated, the moisture turns into steam, which can cause bubbles or voids to form in the printed object. Moisture can also cause problems with adhesion between layers, resulting in a finished product that is weaker and less durable than it should be. eSUN is a highly established name in the 3D printing world. They’re very well known for making high quality filament, environment-friendly resins, and now, they’ve come up with a brilliant filament dryer as well.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.
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.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. While others have praised how it’s very effective for drying Nylon and PETG, and some also spoke of the great customer service, many complained about the absence of a humidity sensor. 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.
