Other features that come in handy are automatic timers and presets for different filament drying. One other thing I think the Sunlu comes up short in is the angle of the print opening for drying while printing. The port is just in a weird position. Its just not good for brittle filaments because the awkward angle. This is pretty easy to eyeball if you are looking for it. As referenced below, the red shows the approximate odd angle for full rolls (which isn’t too bad for low rolls). I got around this problem by using a piece of PTFE tube in the port (which appears to be exactly the right size for that, so they likely intended this, but didn’t tell the buyers). This tube allows the filament to bend at a more friendly radius. 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.

You can also use it to store and dry your food, apart from 3D printing filament. People have admired its ease of use, easy cleaning, and top-notch effectiveness. More expensive than other options. But, it’s the best filament drying box around – you get what you pay for. 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. Compared with the mainstream filament dryers currently on the 3D printing market, we believe that Polyphemus is leading in terms of functionality. 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.

Does PLA Need a Dry Box?

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. 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. 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.

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. 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. 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. 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. The SUNLU Dry Box aims to maintain a constant temperature and prevents excessive heating that could potentially damage the filament.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. Lower costs: You won’t have to buy more filaments because of damage caused by moisture, and you will save on costs in the process. Also, you won’t have to experiment with a lot of temperatures to heat the filament to reach the appropriate temperature for printing. He did mention though that the build quality in his opinion wasn’t at the highest level, but still works nonetheless.
