Standard Configuration with 28 Lasers: Precision and Efficiency Elevated – Hanbang Laser Unveils the E1600 Ultra-Large Aerospace Additive Manufacturing Solution

In March 2025, Hanbang Laser officially launched the next-generation, ultra-large-format metal 3D printer, the HBD E1600. Engineered as an industrial-grade solution tailored to the aerospace sector, the E1600 redefines the standards of efficient, stable, and secure large-scale metal additive manufacturing. Featuring a build envelope exceeding one meter, multi-laser collaborative manufacturing capability, and a fully intelligent closed-loop production system, it delivers groundbreaking support for the fabrication of complex structural components.

Ultra-Large Build Volume: Breaking Through the Limits of Manufacturing

At the heart of the HBD E1600 lies a monumental build volume of 1600mm × 1600mm × 1750mm, designed specifically to meet the aerospace industry’s growing demand for large-scale, highly intricate components. This expansive platform transcends traditional equipment limitations, enabling the seamless fabrication of critical aerospace parts. By reducing assembly requirements, it significantly enhances structural integrity and reliability.

High-Speed Galvanometer Laser System: Dual Advancement in Efficiency and Precision

Equipped with a standard 28-laser configuration, the HBD E1600 leverages an independently developed galvanometer system. Its dynamic multi-beam coordination technology and superior scanning fidelity deliver elevated printing precision. Complemented by rapid dynamic response, it achieves a 40% increase in overall printing efficiency. Spatial optimization allows for a denser laser arrangement, expandable up to 70 lasers as needed. Furthermore, an intelligent multi-beam auto-stitching algorithm completes seamless calibration within five minutes—streamlining operation and boosting the dimensional accuracy and throughput of large-scale component production.

Intelligent Powder Spreading System: Industrial-Grade Efficiency Without Interruption

The E1600 features an integrated, high-rigidity bidirectional powder spreading mechanism, ready for immediate deployment. This system ensures a dual leap in precision and speed. With dynamic intelligent spreading, the machine reaches speeds up to 300mm/s in non-printing zones, doubling efficiency and achieving a single-layer spread in as little as 12 seconds.

An automatic blade replacement system further enhances continuous production capabilities. Real-time wear monitoring and a fully automated replacement process, paired with a dual-blade redundancy design, allow for extended, uninterrupted printing cycles—eliminating downtime typically caused by maintenance interruptions in conventional equipment. With its industrial-grade stability and adaptive intelligence, the HBD E1600 lays a solid foundation for the sustained, reliable production of complex aerospace parts.

Closed-Loop Powder System + Self-Cleaning Optics: Dual Safeguards for Print Quality

The E1600 is equipped with an advanced, fully enclosed powder management system. During operation, it supports automated powder recycling, sieving, and delivery across single or multiple units. This precise control mechanism maximizes powder utilization, minimizes waste, and ensures seamless, high-efficiency workflows—thereby maintaining consistent output quality.

Its optical self-cleaning system employs automated pulsed cleaning for each laser lens during the build process, effectively removing dust particles. This prevents optical degradation, safeguards sensitive components from contamination, and mitigates the risk of damage. Additionally, it significantly reduces downtime associated with manual maintenance, slashing long-term operational and service costs—making it a cost-effective safeguard for high-precision metal 3D printing.

The launch of the HBD E1600 by Hanbang Laser marks a new era in ultra-large metal additive manufacturing. With industrial-grade stability and intelligent, high-efficiency production capabilities, it offers the aerospace industry a transformative solution. Moving forward, Hanbang Laser remains committed to its core philosophy of “ultra-stability, high-efficiency, and full intelligence,” delivering more reliable and economical additive manufacturing solutions for advanced industries.
