Laser Powder Bed Fusion LPBF
Most mature, highest-adoption metal AM process for precision aerospace, medical, and industrial components.
A laser selectively melts and fuses metal powder in successive layers within an inert-atmosphere build chamber. Powder is spread in 20–100 µm layers; one or more lasers trace the part cross-section at each layer. Supports are required for overhanging features and heat management.
Also known as: SLM, DMLS, LaserCUSING
Ti-6Al-4V, AlSi10Mg, IN718, IN625, 316L stainless, 17-4 PH
- 01High geometric complexity including internal channels, lattices, topology-optimized structures
- 02Excellent mechanical properties approaching or exceeding wrought for many alloys
- 03Strong aerospace and medical qualification heritage (AS9100, ISO 13485)
- 04Wide materials library and growing parameter database
- 05Part consolidation eliminates assembly joints
- 01Build speed limited by single-laser systems; multi-laser helps but increases cost
- 02Powder handling complexity, safety, and traceability requirements
- 03Residual stress requires stress relief and often HIP post-processing
- 04Support structures add material, time, and removal labor
- 05Qualification cost is high for flight-critical parts
- 01Aerospace fuel nozzles (GE LEAP — 25% weight savings, 5× life improvement)
- 02Orthopedic implants (porous trabecular structures for osseointegration)
- 03Turbine blades and vanes with conformal cooling
- 04Rocket engine components (injectors, thrust chambers)
- 05Dental crowns and surgical guides
- 06Industrial tooling with conformal cooling

Continued multi-laser scaling (8–20 laser systems), AI-driven in-situ monitoring for closed-loop quality, automated depowdering and post-processing cells, qualified parameter libraries for more alloys, and incremental cost reduction through powder recycling and yield improvement. Large-format LPBF (1m+ build volumes) emerging for aerospace structural parts.
Promising for higher-volume metal parts post-sintering. Industrialization slower than early hype suggested. Active production deployments in automotive and industrial sectors.
Defense and maintenance-relevant technology for repair and metal deposition with low thermal input. Growing in military sustainment and selected industrial repair applications.
Growing for repair, cladding, large metal parts, and hybrid manufacturing. More adoption in defense, aerospace MRO, and energy.
Niche but well-established for titanium orthopedic implants and selected aerospace applications. Arcam (GE Additive) is the dominant supplier.
