Directed Energy Deposition
FormAlloy L2
The FormAlloy™ L2 is a laser powder directed energy deposition (L-DED) system built around a 1 kW continuous-wave 1070 nm IR laser and dual independent powder feeders. It is our primary platform for multi-material deposition, functionally graded materials, repair and cladding studies, and in-situ process monitoring of the powder stream and melt pool.
- Laser 1 kW continuous-wave IR laser, 1070 nm (1.2 mm focused spot)
- Powder Feeders Dual, independently controlled
- Motion Multi-axis deposition head
- Monitoring Melt pool and powder stream imaging
- Deposition Head FormAlloy AX coaxial, 4-stream powder nozzle
- Build Volume 250 × 250 × 300 mm
- Atmosphere Inert chamber, O₂ and H₂O < 100 ppm
Unique Capabilities
- 1 kW continuous-wave IR laser (1070 nm)High continuous-wave power supports stable, high-deposition-rate builds with deep, consistent melt pools across a wide range of structural alloys.
- Dual powder feeders for graded buildsTwo independently metered feedstocks can be blended on the fly to deposit functionally graded materials and dissimilar-metal transitions.
- In-situ process monitoringOptical access for high-speed imaging of the powder stream and melt pool supports multi-scale characterization from macro flow to individual particle tracking.
- Repair and feature additionDeposition onto existing components for repair, cladding, and hybrid manufacturing workflows.
Typical Applications at MMRL
Multi-scale in-situ powder stream characterization, functionally graded material deposition, dissimilar metal joining, and process parameter development for nuclear and aerospace repair applications.
