Introduction

As global high-end manufacturing accelerates toward greater precision, integration, and lightweight design, additive manufacturing (AM) is entering a transformative stage. In industries such as aerospace, medical implants, and precision tooling—where structural complexity and consistency are paramount—traditional processes struggle with efficiency, accuracy, and repeatability.

To overcome these challenges, Han’s Laser has introduced the HLW-1000/3000, China’s first 14/50 dual-beam fiber laser for 3D printing applications. This breakthrough leverages a dual-beam coordinated control architecture to improve build density, stability, and overall efficiency. By minimizing support structures and post-processing requirements, it sets a new benchmark for high-performance additive manufacturing.

Dual-Beam Technology: Unlocking a New Standard in Performance

Addressing High-Value Applications

In advanced sectors such as energy, automotive, and aerospace, joining and printing processes must reliably handle highly reflective metals like copper and aluminum. Conventional single-beam systems often suffer from spatter, poor weld consistency, and process instability. Dual-beam annular spot welding technology provides a precise energy distribution that stabilizes the melt pool, dramatically reducing these limitations.

The Cooperative Beam Advantage

Han’s Laser’s dual-beam annular spot approach utilizes an “outer-ring preheat + inner-core deep penetration” mechanism:

• Outer ring beam: Preheats the material, suppresses reflection, and stabilizes the melt pool.
• Inner beam: Efficiently couples energy into the preconditioned zone, forming a stable keyhole and uniform deep weld.

This synergy ensures accurate thermal control, smoother bead geometry, and higher mechanical integrity, unlocking new possibilities for reflective and complex alloys.

Key Product Features

1.Mode Flexibility

Supports both single-mode (tight focus, high precision) and multi-mode (uniform distribution, high throughput) configurations, giving users unmatched adaptability.

2.Reduced Spatter

Optimized melt flow directs material to the bottom of the pool, minimizing gas entrapment and improving part density.

3.Productivity Boost

Different beam modes can be applied to different build zones—coarse features with multi-mode for speed, fine details with single-mode for accuracy—cutting overall print time and reducing cost per part.

4.High-Value Applications

Enables precision AM for implants, lightweight aerospace parts, energy components, and high-value molds, creating new revenue opportunities in emerging markets.

Dual-Beam Printing: Quality and Efficiency Combined

Compared with single-beam approaches, the 14/50 dual-beam fiber laser significantly reduces porosity and spatter while ensuring smoother solidification. Large structural parts and intricate micro-features can now be manufactured with higher reproducibility and surface quality.

Han’s Laser’s design also supports rapid mode switching, enabling up to six times faster deposition rates in multi-mode while maintaining fine resolution when required. This makes it an ideal solution for large-scale, high-value production environments.
