Bambu Lab AMS 2 Pro - Sistema automático de materiales

The Bambu Lab AMS 2 Pro is the evolution of the automatic filament management system, offering multi-material printing of up to 24 spools in series and intelligent filament drying. With electromagnetic ventilation, a drying temperature of 65 °C, and brushless ultrasonic feeding, it guarantees a fast, dry, and precise material flow on your Bambu Lab printer and represents a new generation of automatic filament management systems for FDM 3D printers.

Initially designed for the H2D range, it also offers full compatibility with the X1 and P1 series, providing an advanced solution for multicolor and multi-material printing. This system can manage up to four filament spools simultaneously, significantly expanding the user's creative and technical possibilities.

It is suitable for a wide variety of 1.75 mm materials, from the most common filaments like PLA, ABS, ASA, and PETG to technical thermoplastics such as PA, PP, PC, and POM. It also allows the use of soluble and support filaments like HIPS, PVA, and BVOH. However, certain materials with particular properties—such as very soft elastomers, damp filaments, or abrasive third-party compounds containing carbon and glass fibers—are not recommended, as they could cause jams or damage the system.

One of the AMS 2 Pro's greatest advances is its ability to preserve filament quality thanks to its hermetic sealing system and the use of internal desiccant material. This mechanism prevents moisture from negatively affecting material performance. An integrated humidity sensor constantly monitors internal conditions and alerts the user if the desiccant needs replacement, which is crucial to avoid problems such as poor layer adhesion or irregular extrusions.

The system automatically recognizes official Bambu Lab filaments via RFID tags, instantly applying the most appropriate parameters for use. For materials from other manufacturers, manual configuration is possible. In case of incidents such as filament tangling or spool blockage, the AMS 2 Pro automatically stops the print, preventing prolonged errors and material waste.

Additionally, this module offers a key feature for users performing long jobs: automatic spool change. When a filament runs out, the system switches to the next one without intervention, allowing printing to continue uninterrupted. This function not only optimizes filament usage but also reduces energy consumption and avoids unnecessary pauses during long or unattended prints.
