Choosing the right Bambu AMS heater can be overwhelming, but it doesn’t have to be. To simplify the process, you can start by asking yourself a few simple questions:
Do I Need to Print Different Filaments Simultaneously?
Different filaments require different drying temperatures. For example, PLA drying temp is around 50°C, while ABS drying temp is around 60°C or higher. If you're frequently switching between filament types—or printing with multiple materials at once—using a single heating environment just doesn’t work well.
That’s where EIBOS Series X: Tetras stands out. It comes with four independent heating and control systems, one for each filament chamber. Each chamber is fully enclosed with its acrylic cover and has a dedicated touchscreen for precise control over both temperature (20–65°C) and humidity (10%–99% RH). It allows you to dry PLA in one chamber while drying PETG or ABS in others, all without interfering with each other.
You also save energy by only heating the chambers you’re actively using. More importantly, you avoid cross-contamination between materials with different drying needs. This is a huge advantage if you’re working on multi-color projects or combining materials with different properties in a single print.
Do I Need Automatic Sealing After Drying?
Keeping your filament at the right humidity level is critical—especially if you live in a humid environment or use moisture-sensitive materials. Even after drying, filaments can quickly reabsorb moisture from the air, which can lead to poor print quality or failed prints.
That’s why EIBOS Tetras includes an intelligent drying system with automatic sealing. As soon as the drying process begins, the system opens a valve to release moisture through an external exhaust. Once the drying is complete, the valve automatically closes to prevent the filament from absorbing moisture again.
This fully automated process removes the need for manual checks or intervention. It’s especially helpful for users working with sensitive materials and for anyone living in areas with high humidity.
Do I want better printing results?
EIBOS Tetras’s two-stage heating system is designed to solve this. In the first stage, it dries the filament thoroughly at a higher temperature. In the second stage, it lowers the temperature slightly to maintain the dryness and support consistent feeding during printing.
This process helps ensure your filament is always in optimal condition—not just before the print starts, but throughout the entire job. That leads to smoother extrusion, better layer bonding, and more reliable results. If you’ve struggled with inconsistent print quality, this feature alone makes a noticeable difference.
Am I Running a Print Farm?
The Bambu AMS is a popular choice for 3D print farms. If you're managing a print farm or handling a high volume of jobs, efficiency is critical. A highly automated Bambu AMS heater: Eibos Tetras is made for that. Each print chamber is heated independently, so you only use power when you need it. The built-in external circulation drying system automatically activates from the moment the unit is turned on. The automatic sealing feature protects the consumables after drying, keeping the internal environment clean and dry without any additional steps.
These features reduce operating costs and simplify filament management across multiple printers. While the upfront cost may be higher than simpler setups, the long-term savings in energy, material waste, and downtime make it a smart investment—especially for businesses running continuous jobs or large-batch prints.
Can I Monitor Filament at a Glance?
Sometimes, all you need is a quick check to make sure there’s enough filament or to confirm that drying is still in progress. But with a fully enclosed system, that usually means opening the AMS and disturbing the environment.
EIBOS Tetras solves this with semi-transparent acrylic covers. You can glance at each chamber to see the filament status without opening anything. This keeps the interior sealed, the drying process uninterrupted, and your workflow efficient. It’s a small detail, but it saves time and adds a lot of convenience—especially if you’re running multiple printers at once.
Conclusion
If you need to dry multiple different materials simultaneously, dry while printing, or just want a more streamlined workflow, EIBOS Series X Tetras offers a smart and scalable solution. Its independent print chamber, dual-stage heating, and transparent design give you serious control and reliability.
