Key advantages of LENS LMD technology in metal 3D printing

High Deposition Efficiency

LENS LMD (Laser Engineered Net Shaping – Laser Metal Deposition) enables rapid material buildup with controlled energy input, making it ideal for large or repair-oriented components. It offers higher deposition rates compared to powder bed fusion, allowing faster production of functional near-net-shape parts. This efficiency significantly reduces manufacturing time for aerospace and power generation components that require fast turnaround with high structural integrity.

Repair and Feature Addition Capability

One of the major strengths of LENS LMD is its ability to repair high-value parts or add localized features without remanufacturing the entire component. This is especially valuable for superalloy turbine blades produced via vacuum investment casting or single crystal casting. Instead of full replacement, damaged areas can be rebuilt layer by layer, saving cost and extending part lifecycle.

Material Flexibility and Superalloy Applicability

LENS LMD supports a wide range of metals, including nickel-based alloys such as Inconel 718, cobalt-based alloys like Stellite 6, and titanium alloys such as Ti-6Al-4V. This makes it highly suitable for high-performance sectors including aerospace and aviation and oil and gas, where temperature resistance and fatigue performance are critical.

Integration With Post-Processes

LMD-produced parts can be seamlessly combined with hot isostatic pressing (HIP) and CNC machining to achieve full densification and precision dimensions. HIP eliminates residual porosity, while CNC machining restores dimensional accuracy and surface finish—allowing final quality to meet aerospace-grade requirements.

Real-Time Process Control

LENS LMD includes in-situ monitoring of melt pool temperature, laser energy, and material flow, enabling real-time control over deposition quality. This reduces production risk and improves consistency of microstructure. When followed by rigorous material testing and analysis, the process ensures mechanical reliability under cyclic load and thermal stress conditions.
