Sunlu FilaDryer S4 filament dryer

3D printing filaments tend to to absorb moisture from the environment, with some materials being more affected than others. This excessive moisture absorption leads to Extrusion problems such as blockages and poor adhesion of the part on the printing surface as well as numerous Quality problems with the 3D-printed part . Filament dryers are devices that remove excess moisture from the filament using heat or heat and a desiccant.

The FilaDryer S4 from Sunlu was developed to dry a variety of materials, including PLA (also wood/marble/silk), ASA, ABS, PA, PC, PETG, HIPS or TPU. The outstanding feature of the FilaDryer S4 is that it It can hold 4 spools of 1 kg of filament each. and with filaments of 1.75 mm, 2.85 mm and 3.00 mm diameter can work. It is also possible to use a 3 kg spool to use. Instructions You can find this information, as well as the corresponding STL files, in the Downloads section .

With the FilaDryer S4 can that Dried filament can be fed directly into a 3D printer. through a hole located at the top of the device. This means enormous time saving in the 3D printing workflow and high print quality. The FilaDryer S4 is equipped with 8 filament holes and PTFE tubes equipped, which the Drying many materials simultaneously and simultaneous printing with multiple filaments made possible.

A very valuable feature of the FilaDryer S4 is that you don't have to guess the drying parameters, as the device is equipped with predefined drying parameters for the most common materials such as PLA, ABS, PETG, PA and PC will be delivered.

Thermal efficiency

Thanks to a intelligent design and maximum use of the interior space Heat dissipation is minimized and the electrical-thermal conversion efficiency of the FilaDryer S4 is significantly improved. The FilaDryer S4 is equipped with a PTC heating element and a triple fan setup equipped. The latter ensures the circulation of heat within the device with a balance of ±3 ºC and ensures that The user-selected temperature is compared to the real-time temperature inside. the dryer's temperature always matches.

This efficient design makes the FilaDryer S4 approximately 7 times more powerful than the The FilaDryer S2 , with a heating power of 330 W, heats up from 25°C to 50°C approximately 50% faster than the FilaDryer S2 and from 25°C to 70°C approximately 37.5% faster. This increased thermal efficiency means Not only faster drying, but also energy and time savings .

The FilaDryer S4 uses all the necessary Safety measures to ensure that the dryer housing does not overheat. Furthermore, the potential risk of coil deformation (and thus rotational problems) due to high temperature exposure is mitigated by adding heat-resistant PTFE hoses reduced filament path. The FilaDryer S4 is also certified with the CE, FC and RoHS certifications .

Moisture management

In addition to providing optimal heat conditions for drying filaments The FilaDryer S4 also controls the humidity levels inside the chamber . Any moisture generated in the dryer's chamber is effectively vented through the eight filament holes in the device's housing.

Furthermore, the FilaDryer S4 includes a High-precision humidity sensor . This sensor displays the real-time humidity level in the dryer chamber when no drying is taking place. When the humidity level reaches or exceeds 50%, The FilaDryer activates automatically and prevents secondary moisture damage.

user-friendly interface

The FilaDryer S4 has a large and practical LCD touchscreen on the front of the device. The touchscreen has a response time of 1 second and Displays temperature, time, humidity, material type, and countdown time . The drying temperature can be set between... 35-70 °C be hired.

Thanks to its intelligent design, heat efficiency, moisture management, and compatibility with a wide variety of materials, the Sunlu FilaDryer S4 The perfect drying device for those who work with 3D printing daily, especially with multiple materials simultaneously or in a multi-printer configuration , such as on a 3D printer farm. The FilaDryer S4 can store up to 4 spools of filament in a humidity-free environment and High-quality prints at any time This can be achieved. The integration of the FilaDryer S4 into the 3D printing workflow ensures a smooth and significantly faster printing process .
