How does SLM solve challenges in complex aerospace and energy geometries?

Integration of Internal Structures

SLM enables the direct fabrication of internal channels, lattice structures and weight-optimized geometries that are difficult or impossible to achieve with machining or traditional casting. For aerospace and energy components requiring efficient thermal management, SLM allows precise formation of cooling passages in alloys like Inconel 713 or CMSX-series alloys, significantly enhancing heat dissipation and fuel efficiency.

High Complexity Without Tooling

SLM eliminates the need for molds or tooling, making it ideal for complex geometries used in aerospace and power generation systems. By building components layer by layer, SLM allows precise replication of aerodynamic shapes, combustor designs and turbine flow channels without deformation or tool-induced stress.

Lightweighting and Structural Optimization

A key advantage of SLM is mass reduction through topology optimization and internal cavities. Titanium alloys such as Ti-6Al-4V are frequently used to create lightweight brackets, housings and rotor components that maintain high strength-to-weight ratios—critical for performance in both aerospace and energy applications.

Hybrid Manufacturing and Post-Process

SLM is often paired with post-processes such as hot isostatic pressing (HIP) and heat treatment to enhance mechanical properties and eliminate porosity. Critical dimensions are finished through EDM or CNC machining, combining additive advantages with high-precision finishing for turbine, combustor and pump components.
