Metal Additive Manufacturing with Laser-Based Directed Energy Deposition (DED)
Build metal structures layer by layer with laser-based Directed Energy Deposition. Designed for large parts, functional features and hybrid manufacturing workflows.
Discuss Your 3D Printing Project →What Is Metal Additive Manufacturing?
Metal additive manufacturing is a production method in which metal material is deposited layer by layer to create three-dimensional structures.
Unlike laser cladding, which focuses on surface improvement and repair, additive manufacturing enables the creation of entirely new three-dimensional structures and functional features.
Why Laser-Based Additive Manufacturing?
Large-Scale Capacity
Suitable for large components and open build volumes exceeding powder-bed system limits.
High Material Efficiency
Material is deposited only where needed, reducing waste and finishing requirements.
Hybrid Manufacturing Ready
Additive deposition can be combined with machining, forging or casting processes. 1064nm fiber laser and 445nm blue laser hybrid head options are available.
Additive Manufacturing Processes
Directed Energy Deposition (DED / LMD)
Directed Energy Deposition creates a melt pool with a focused laser beam while continuously feeding metal powder or wire into the process zone. Material solidifies track by track and layer by layer, producing dense metal structures.
Key Features
- Powder- or wire-fed deposition
- Flexible build size and geometry
- Ideal for structural features, reinforcements and part modification
Typical Additive Manufacturing Applications
Used for structural production, reinforcement and hybrid manufacturing in aerospace, energy and heavy industry components.
Aerospace & Defense Components
Direct laser deposition production of lightweight, high-performance structural parts and functional features.
Large Structural Components
Layer-by-layer production of large parts exceeding the build volume limits of powder-bed systems.
Functional Prototyping
Rapid production of new geometries and functional features directly in metal.
Mold & Tool Repair/Modification
Adding new geometry to existing molds and tools, or structurally reinforcing worn areas.
Energy & Turbine Components
Structural production and repair of high-value components with complex geometries, such as turbine wheels.
Hybrid Manufacturing (Machining + Deposition)
Hybrid manufacturing workflows combining additive deposition with CNC machining, forging or casting.
Which Industries Use It?
Who Chooses This?
Teams responsible for production/R&D processes in the sectors above typically turn to laser-based additive manufacturing for the following needs:
R&D & Design Engineers
Teams wanting to produce large or complex-geometry parts directly in metal, exceeding the build volume limits of powder-bed systems.
Mold & Tooling Managers
Maintenance and manufacturing teams wanting to add new geometry to existing molds/tools or structurally repair worn areas.
Production Engineers
Teams wanting to integrate additive deposition into a CNC machining, forging or casting line, establishing a hybrid manufacturing workflow.
Why High-Power Diode Laser?
Designed for stable processes, easy system integration and industrial-scale production.
Stable Melt Pool
Homogeneous energy distribution ensures low dilution and a narrow heat-affected zone (HAZ).
Minimum Deformation
Controlled heat input minimizes thermal deformation on precision geometries.
Modular Design
Modular laser and optics architecture simplifies system integration and long-term maintenance.
300W – 100kW Platform
A single unified diode laser platform, from small functional features to large structural components.
Automation-Ready
Designed for seamless integration with robots, gantry systems and CNC machines.
When Should Laser-Based Additive Manufacturing Be Chosen?
If one or more of the following apply to you, laser-based additive manufacturing is technically worth evaluating.
- If the part exceeds the build volume limits of powder-bed systems
- If new geometry/functional features need to be added to an existing part
- If additive manufacturing needs to be combined with CNC machining, forging or casting (hybrid manufacturing)
- If reducing material waste and finishing time is a priority
