How do SLM-printed AlSi10Mg properties compare to traditional parts?

Improved Microstructure and Strength

SLM-printed AlSi10Mg parts feature a much finer and more uniform microstructure than cast or machined components. Rapid solidification leads to enhanced tensile strength and stiffness, making SLM parts suitable for lightweight structural applications in aerospace and aviation and automotive sectors.

Enhanced Fatigue Performance

While traditional parts often suffer from localized stress concentration, SLM allows topology optimization and controlled material distribution. This improves fatigue resistance and extends service life, especially in vibration- and load-sensitive systems such as power generation modules.

Complex Design Capability

Traditional machining and casting have limitations in producing hollow structures, internal flow paths and lattice geometries. SLM overcomes these constraints, enabling weight reduction without compromising strength. This makes AlSi10Mg SLM components far more efficient for thermal and structural applications.

Post-Processing Potential

Precision finishing via CNC machining and optional heat treatment further align SLM properties with aerospace-grade requirements. Traditional parts typically require more machining effort and still cannot match the geometric flexibility offered by additive manufacturing.
