Dual Blue™: Laser Additive Manufacturing - Wire and Powder in One Platform
The Dual Blue™ system is a powerful blue laser additive manufacturing platform that supports wire, powder, or hybrid deposition—all in one machine. Designed for industrial-scale production, DualBlue delivers unmatched flexibility, precision, and performance for demanding metal AM applications.

Key Features of Dual Blue™ Laser Additive System
Leveraging One Off Robotics’ full technology stack, the Dual Blue system brings together proven laser wire and laser powder additive manufacturing into a single, integrated platform. Purpose-built for high-performance metal AM, it combines large-format capability, advanced thermal control, and real-time process monitoring to meet the most demanding industrial applications.
-
Dual Blue combines Laser Wire Additive Manufacturing (LWAM) and Laser Powder Additive Manufacturing in a single machine switch between wire, powder, or hybrid deposition with no hardware changeover.
-
Equipped with advanced blue laser sources for higher absorption efficiency in reflective metals like copper, titanium, and nickel, enabling better quality, speed, and material flexibility.
-
Industrial grade rotary positioner supports large format parts with precision movement and robust part handling ideal for aerospace, defense, and energy sectors.
-
Engineered for production environments, Dual Blue delivers consistent results across large build volumes with near net shape capabilities and reduced post processing.
-
Includes real-time thermal imaging, layer tracking, and closed-loop quality feedback through One Off’s proprietary software suite ensuring each layer meets spec.
Why Choose a Blue Laser for Additive Manufacturing
Blue lasers deliver significantly higher absorptivity in reflective metals such as copper, aluminum, and gold compared to traditional infrared (IR) lasers. This makes blue laser additive manufacturing the superior choice for applications requiring precise energy input, cleaner melt pools, and better material compatibility.
With Dual Blue, manufacturers gain the flexibility to process high-value materials that are difficult or inefficient to print using IR-based systems. Whether you're working with Cu-ETP, Al, or other thermally reflective metals, blue laser technology ensures better energy coupling, faster deposition, and more consistent results.
Key Advantages of Blue Laser AM:
Enhanced printing quality for copper, aluminum, and gold
Reduced spatter and defects through stable melt pool formation
Lower power requirements due to higher absorption efficiency
Expanded material capabilities in high-performance industries
