AZ91D magnesium delivers exceptional strength-to-weight performance, achieving a 50% mass reduction compared to 6061 aluminum and 30% lower weight than carbon fiber. This directly increases payload capability and flight endurance.
We utilize a sealed argon chamber environment maintaining oxygen content below 10 ppm, active 200°C stress relief pre-heating, explosion-proof CNC enclosures, dedicated fire suppression, and strict NFPA 484 compliant protocols.
As-printed SLM components achieve ±0.1 mm accuracy, while precision 5-axis CNC finishing achieves ±0.025 mm, and jig grinding operations reach tolerances as tight as ±0.002 mm with surface roughness down to Ra <0.2 μm.
Components undergo comprehensive ASTM E8/E9 mechanical testing, ASTM B117 salt spray corrosion testing, MIL-STD-810G vibration endurance validation, non-destructive CT scanning, and MIL-SPEC pullout thread inspections.
Yes. The SLM additive process allows engineered internal lattice structures with up to 80% porosity and cell sizes from 2 to 5 mm, delivering high energy absorption, superior damping, and EMI shielding.
By combining direct digital additive manufacturing with multi-spindle and 5-axis CNC machining, we deliver batch-of-one components—such as custom medical implants and prototype UAV parts—without retooling downtime.
