We’re proud to introduce EIBOS Series X: Tetras — a revolutionary enhancement purpose-built for Bambu Lab AMS users. EIBOS Series X: Tetras seamlessly integrates advanced filament drying technology into your existing Automatic Material System (Bambu AMS), transforming it into a comprehensive, moisture-free solution for filament storage and high-quality 3D printing.
No longer do you have to choose between vivid color prints and proper filament care — now, you can have both.
Why EIBOS Series X: Tetras?
While Bambu AMS offers a sealed environment and automatic filament switching, it lacks one essential function: active dehumidification. Most common 3D printing materials, such as PLA, PETG, TPU, and Nylon (PA), are inherently hygroscopic — they absorb moisture from the surrounding air, especially in humid environments.
Even when stored in AMS, filaments remain vulnerable to moisture during:
-
Print preparation stages
-
Pauses or delays during a print job
-
Waiting time during multi-color transitions
Moisture penetrates the filament’s surface and core, leading to a range of print defects:
stringing, nozzle clogs, layer misalignment, and poor bed adhesion.
EIBOS Series X: Tetras was created to solve this core limitation of the AMS — preventing print failures caused by filament moisture during real-time use. It ensures that your AMS isn’t just a storage and feeding system, but a fully-fledged active drying solution.
What Does EIBOS Series X: Tetras Offer?
1. Plug-and-Play Installation
Tetras is designed for effortless integration. There’s no need to modify your Bambu AMS hardware or printer firmware. It runs on an independent power and control system, so drying and printing can happen simultaneously with no time restrictions. This means your filament stays dry throughout the entire print cycle, reducing issues like stringing, warping, or under-extrusion — ultimately saving time and improving print reliability.
2. Active Drying
Tetras transforms your Bambu AMS into four independently controlled drying chambers. Each chamber is fully isolated and allows for customized drying parameters depending on the material type. This ensures that each spool maintains its optimal temperature and humidity level.
EIBOS Series X: Tetras system employs an external air circulation drying mechanism — it forces dry air into each sealed chamber and continuously evacuates moisture. This fast, efficient airflow both accelerates drying and prevents moisture from re-entering the chamber.
Furthermore, Tetras introduces a two-stage drying process:
-
Stage 1: Aggressively removes moisture from the filament.
-
Stage 2: Applies gentle heat to maintain consistent feeding, reduce friction, and support stable extrusion throughout the print.
3. Smart Storage
Once drying is complete, EIBOS Series X: Tetras switches to Smart Storage Mode. The air outlet is automatically sealed, preventing ambient humidity from entering. You can configure the humidity threshold, and Tetras will automatically resume drying if the internal humidity rises above your set level. This guarantees that your filaments remain dry at all times, even between print jobs.
Last Words
EIBOS Series X: Tetras isn't just an accessory — it's a critical upgrade for any Bambu Lab AMS user serious about print quality and filament protection. It addresses the single largest gap in Bambu AMS design by introducing intelligent, multi-zone drying and storage — without compromising usability or printer compatibility.
With EIBOS Series X: Tetras, you’re not just printing — you're printing with confidence.
