Features

  • 1,[Dual-Zone Design] An insulating partition has been added inside the chamber to create left and right zones that operate independently without interfering with each other.One screen controls two chambers for effortless operation.
  • 2,[Independent Temperature Control] The S4Pro features a dual-channel independent heating system. With independent temperature control across two zones (4585C), it can dry different filaments simultaneously.
  • 3,[Professional Annealing] MO2: Annealing Mode; After printing a functional filament model, it must be annealed for 23 hours in a chamber maintained at 7085C. The S4Ppro drying oven provides this environment, allowing creators of functional filaments to unleash their creativity.
  • 4,[Smart Humidity Control] The MO3 mode intelligently regulates humidity inside the chamber. It automatically activates when the internal humidity reaches the set range (30%50%) and stops once the humidity drops to 25%, preventing the filament from repeatedly becoming damp.

    • Great dryer for multiple filaments.
Color: S4 Pro Black
Review Image by ThomasT
Great dryer for your filaments. 2 separate compartments so 2 kinds of filament at the same time. It’s large so make sure you have room.

    • The Filament Dryer I Wish I Had Bought Sooner
Color: S4 Pro Black
This filament dryer has been an outstanding addition to my 3D printing setup. If you're serious about printing, especially with multiple materials, this is one of the most worthwhile upgrades you can make. The dual-zone design is fantastic. Being able to dry different filament types at different temperatures at the same time is incredibly useful. I can have PLA on one side while drying PETG or another material on the other without having to compromise on settings. The four-spool capacity is another huge advantage. Instead of constantly swapping rolls in and out, I can dry several spools at once or leave frequently used materials ready to print. Heating performance is excellent. It reaches temperature quickly and maintains it consistently, and the ability to go all the way up to 85°C opens the door for properly drying more demanding materials like Nylon and PC. The annealing mode is also a great bonus for anyone printing functional parts. The humidity control works exactly as advertised, automatically keeping filament dry without constantly running the heater. It's one of those features you don't realize you need until you have it. The interface is simple to use despite all the available features, and the overall build quality feels solid and well thought out. It has become a permanent part of my printing setup. Most importantly, the results speak for themselves. I've seen noticeably cleaner prints, fewer stringing issues, and much more consistent performance from moisture-sensitive filaments. I absolutely love this dryer. It's easily one of the best additions I've made to my 3D printing setup and is worth every penny. Five stars. ... show more

    • Must get this, its amazing for filament
Color: S4 Pro Black
Super easy to use and setup. Works great at drying multiple filaments, and different types of filaments in each part. Increases quality of prints by removing moisture, and gives you a great place to store it moisture free. Print adhesion is much better, along with you appearance of prints. Compatible with any printer, you can feed directly to your printer for single color prints. Well worth the price with the savings you get from saved filaments. ... show more
