SUNLU Filament Dryer S2 Assessment: Guide, Temperature, Assessments

The standard of 3D prints typically drops when chilly and moist climate arrives. Excessive humidity within the air, rain, snow, and storms finally negatively have an effect on your 3D printing supplies. For instance, some filaments take in moisture, leading to failed prints, and that’s when a very good filament dryer turns out to be useful. Let’s unbox and evaluation the brand new SUNLU filament dryer, Filadryer S2, to see how this small system can dry PLA, ABS, PETG, and different plastics and enable you 3D print excellent fashions.

How a lot moisture can your filament take in? All the things relies on its hygroscopicity attribute. Hygroscopicity is the supplies’ property to soak up moisture from the encircling setting. Some merchandise, similar to SBS, don’t require the utilization of filament dryers as a result of they don’t take in any moisture. However others, similar to ABS, PETG, and PLA, take in it too effectively.
