Materials

The powder’s characteristics influence the quality and mechanical properties of the end part.

Different types of powders dedicated to the various additive manufacturing processes.

Material Selection Considerations

• Definition of specifications in compliance with the end-use application and materials
• Characterization of the powder and validation of a given process
• End part before post-treatment and control

Key metal powder characteristics for additive manufacturing

- Chemical composition
- Powder size distribution (PSD)
- Morphology
- Physical properties

How to characterize the powder’s microstructure?

- Observing the morphology with a Scanning Electron Microscope
- Checking the chemical composition: elemental analysis (EDS, X-ray fluorescence), ICP
- Identifying the size distribution: screening, laser granulometer
- Flow capacity: Hall Flowmeter, FreemanFT4

Usual powders for metal additive manufacturing

- Aluminum alloys: AlSi10Mg, AlSi7Mg, AlSil2
- Titanium alloys: Ti6Al4V
- Steel: 316L, 17-4PH, 15-5PH
- Nickel-based alloys: Inconel 625, 718, 939, 738, Hastelloy X
- Cobalt Chrome: CoCr

Why choose a spherical powder for powder bed processes?

- Increase particle density
- Expand packed density and compactness of the powder bed
- Improve the capacity of powder flow

Usual powders for thermoplastics additive manufacturing

- Acrylonitile butadiene styrene (ABS)
- Polylactic acid (PLA)
- Polyvinyl alcohol (PVA)
- Polycarbonate
