SLM vs DMLS Metal Additive Manufacturing Technology Comparison
Comprehensive comparison of Selective Laser Melting and Direct Metal Laser Sintering technologies
SLM
Selective Laser Melting
- Process Principle: Full melting of metal powder
- Material Compatibility: Pure metals (Ti, Al, stainless steel, etc.)
- Part Density: ≥99.5%, excellent mechanical properties
- Applications: Aerospace structural components, medical implants
- Equipment Cost: Relatively high, suitable for mass production
DMLS
Direct Metal Laser Sintering
- Process Principle: Partial sintering with controlled porosity
- Material Compatibility: Multi-component alloys (Ni-based, Ti alloys, etc.)
- Part Density: 95%-98%, excellent toughness
- Applications: Engine turbine blades, complex geometries
- Equipment Cost: Relatively lower, suitable for small-batch customization
Technical Parameter Comparison
| Parameter | SLM (Selective Laser Melting) | DMLS (Direct Metal Laser Sintering) |
|---|---|---|
| Fusion Mechanism | Full melting creating dense melt pools | Partial sintering with controlled porosity |
| Material Compatibility | Pure metals (Ti, Al, stainless steel, etc.) | Multi-component alloys (Ni-based, Ti alloys, etc.) |
| Part Properties | ≥99.5% density, high mechanical strength | 95%-98% density, excellent toughness |
| Process Characteristics | High residual stress requires support structures | Suitable for complex hollow structures |
| Cost Efficiency | Higher equipment cost, suitable for mass production | Lower cost, suitable for small-batch customization |
