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. 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. 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. 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.

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. It also includes a single power button from where you can turn it on and off conveniently, unlike what was demanded in the SUNLU Filament Dryer. 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. 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.

Does PLA Need a Dry Box?

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. 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. Thee spacious chamber, multiple heater fans, and compatibility with various materials make the S4 perfect for those constantly switching filaments across multiple printers. 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 More expensive than other options. But, it’s the best filament drying box around – you get what you pay for.

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. 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. 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. 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. 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.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. 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.
