Applications
Frequently Asked Questions (FAQ)
They are produced using a state-of-the-art hybrid process combining additive Selective Laser Melting (SLM) with high-precision 5-axis CNC machining, achieving 99.8% material density and optical flatness.
As-printed surfaces (Ra 10–15µm) are refined down to Ra 0.1–0.4µm on critical surfaces, featuring 0.01mm/m flatness and tolerances of ±0.025mm for critical features.
The housings comply with MIL-STD-810 (environmental stress), MIL-STD-461G (EMI shielding), MIL-I-45208A (inspection), MIL-PRF-38534 (electronic enclosures), and MIL-STD-883 for traceability.
Topology optimization yields a 15% weight reduction, while near-net-shape printing with integrated cooling channels eliminates multi-component assemblies, slashing overall lead times by 40%.
In addition to AlSi10Mg aerospace solutions, material capabilities include Copper, Pure Copper, and Bronze, with ceramic Binder Jetting, Ceramic SLA, and Continuous Fiber Reinforcement methods.
Key applications include tactical missile guidance systems, UAV avionics enclosures, radar and targeting components, satellite communications, and electronic warfare hardware.
