Sunlu Filadryer S4 Filament Dryer

Good unit, easy to set up and use

Simple to set up and use. Time will tell but looks good so far.

Works like a charm, quieter than the printer itself.

The Sunlu Filadryer S4 has quickly become an indispensable tool in my 3D printing arsenal, earning a solid 5-star rating. As someone who values print quality and consistency, I've struggled with the challenges of moisture-laden filament. This dryer has been a game-changer, rescuing countless spools and elevating my printing results.

Here's why I'm so impressed:

Effective Drying: The S4 efficiently removes moisture from various filament types, restoring them to their optimal printing condition. I've seen significant improvements in print quality, with reduced stringing, blobbing, and layer adhesion issues.  
Large Capacity: With the ability to hold up to four filament spools simultaneously, the S4 is perfect for busy printing setups or those with a diverse material collection.  
User-Friendly Interface: The intuitive touchscreen controls make it easy to set drying temperatures and durations. The real-time humidity display provides valuable feedback on the drying progress.  
Versatile Functionality: The S4 offers both timed drying and automatic humidity control modes, catering to different needs and preferences. The ability to feed filament directly from the dryer to the printer is a convenient bonus.  
Sturdy Construction: The dryer feels well-built and durable, ensuring long-lasting performance. The compact design doesn't take up excessive space on my workbench.
While the S4 excels in most areas, there are a couple of minor considerations:

Fan Noise: The fans can be a bit noisy, especially at higher speeds. However, this is a common trait among filament dryers.  
Size: The S4 is relatively large, which might be a concern for those with limited space.

Overall, the Sunlu Filadryer S4 is an outstanding filament dryer that delivers exceptional performance and value. It's a must-have for any serious 3D printing enthusiast looking to improve print quality and extend the lifespan of their filament collection.

Fantastic product and process to receive the product. Thank you.

I got caught out by the red power switch at the back of the dryer when first turning it on. The red switch did not illuminate when powering on so I thought it was DOA. However after overthinking the problem I had a look at the front screen and noticed the touch screen power button was on, after pressing this the unit turned on. Used it already and it works like a charm. The fans are a bit noisy but other than that a very nice piece of equipment.
Phaser FPV were ultra-fast shipping it out on the same day I ordered it, than you.

When I set up my Voron 0.2 I decided I needed a drier for more than a single roll of filament at a time. Having already got the Sunlu S2 staying with the same brand was a no brainer, due it it being so reliable. Whilst this is a large drier, and a fair bit noisier than the S2 as the S4 has multiple fans, it does an amazing job of drying out my filament in humid Wellington, NZ. Phaser FPV had an amazing price on this. I have ordered from them quite a few times now and their service is always awesome and very fast deliveries

I will get three more to fill the cabinet soon, they work well. Also shipping was super-fast and came with no damage!
