AMCM Unveils AirSword Gas Flow Concept for Enhanced Large-Scale PBF-LB Additive Manufacturing

Introduction to the AirSword Gas Flow Concept

AMCM GmbH, based in Starnberg, Germany, has introduced a groundbreaking solution in the world of Additive Manufacturing. The AirSword gas flow concept is designed to significantly improve the performance of large-format Laser Beam Powder Bed Fusion (PBF-LB) machines. With an innovative approach to gas flow, AirSword aims to solve the common challenges associated with large-scale additive manufacturing, especially in systems such as the M 8K and the upcoming M 10K.

Key Features of the AirSword Concept

The AirSword gas flow system addresses the inefficiencies of traditional gas flow methods, which often struggle in larger spaces, causing uneven distribution, turbulence, and suboptimal production results. As the need for consistent, high-quality production intensifies in industries requiring long-duration builds, AMCM’s AirSword provides a dynamic, multi-layered, and seamless gas flow that spans the entire building area. This advanced design ensures optimal process conditions, even in large chambers like those of the M 8K.

A critical advantage of the AirSword system is its ability to manage smoke and soot effectively. The system’s central gas-emitting device splits the gas flow into two opposing streams, pushing smoke and soot towards the exhaust. This prevents laser-smoke interaction and ensures that the laser’s performance remains unaffected, leading to cleaner, interference-free prints. Additionally, the AirSword’s ceiling-directed stream keeps the cover glasses and laser path free of smoke, ensuring consistent laser quality throughout extended builds.

Enhanced Efficiency and Reduced Maintenance Downtime

One of the most significant benefits of the AirSword gas flow system is its potential to drastically reduce maintenance downtime, which is crucial for high-volume manufacturing. By keeping the laser optics clear of soot and vapour, the system ensures a steady and uninterrupted production process. This improved operational efficiency leads to increased productivity, particularly in industries that require long-term, high-volume additive manufacturing, such as aerospace and automotive.

The AirSword’s ability to maintain a uniform protective gas atmosphere across the powder bed allows the M 8K and M 10K systems to operate at peak performance levels. The seamless gas flow ensures the production of high-precision components even during lengthy printing processes, while integrated technologies like SmartFusion and EOSTATE Exposure OT further optimize in-process quality assurance.

AirSword’s Integration with AMCM’s M 8K and M 10K Systems

The M 8K, a large-format additive manufacturing system from AMCM, features eight 1 kW lasers and a 0.7 m² powder bed, enabling the creation of intricate, high-precision components. With a build volume of 800 x 800 x 1200 mm, the system is designed for high-productivity applications. The AirSword system complements the M 8K’s capabilities by maintaining a uniform gas flow across the expansive powder bed, ensuring consistent quality over long build times.

AMCM’s upcoming M 10K system takes things a step further with a 1000 x 1000 mm build area. The integration of AirSword in the M 10K ensures that even larger systems can maintain the same high-quality standards and productivity levels as the M 8K. The combination of superior laser, scanner, and optics design, coupled with the AirSword gas flow concept, guarantees reliability and minimizes the risk of quality loss during extended builds.
