DEFINITION OF POWDER REQUIREMENTS

We advise users on the definition of their specifications and on the means of characterisation for the quality control of the powder before manufacturing the part: X-ray diffractometer, laser granulometer, pycnometer, scanning electron microscope, hall effect flowmeter, etc. These powders can be validated with partner users. 

SELECTION OF THE MOST SUITABLE MATERIAL

Multistation offers several materials, including :

  • Stainless steel: 316L, 304L, 308L, 17-4PH, 15-5PH, 1.2709
  • Nickel based alloy: IN625, IN718, IN939, Hastelloy X
  • Cobalt based alloys: Co-Cr, SLM MediDent
  • Titanium alloys: Pure Titanium, Ti6Al4V
  • Aluminium alloys: AlSi10Mg, AlSi7Mg, AlSi12, AlSi9Cu3, AlMg4.5Mn0.4
  • Other materials on request

METAL POWDER PROCESSES

Metal powders are useful for some metal additive manufacturing processes such as Powder Bed Fusion (PBF), Directed Energy Deposition (DED), binder jetting or cold spray. Suitable particle sizes are available for each process. The material and particle size of the powders are essential to obtain an acceptable finished part. Other parameters such as gas inclusions or the presence of satellites are also important and contribute to the quality of the printed part. Multistation and its suppliers are committed to obtaining the highest quality powder possible.

FAST DELIVERY WITH CERTIFICATES OF ANALYSIS

Multistation is committed to the prompt delivery of powders once they are obtained. They are supplied with certificates of analysis and comply with the certifications (chemical composition, particle size distribution, bulk and tapped density, flowability test, morphology…)

We offer not only powders selected by the machine manufacturers but also from different powder producers referenced in the field of additive manufacturing.

QUESTIONS AND ANSWERS 

WHAT IS THE MANUFACTURING METHOD FOR METAL POWDERS? 

  • Gas atomisation (Argon, Nitrogen)
  • Plasma atomisation
  • Rotating electrode atomisation

WHY CHOOSE A SPHERICAL POWDER FOR POWDER BED PROCESSES? 

  • To increase particle density
  • To improve the surface appearance of the part
  • To homogenise the spread of the powder

HOW TO CHARACTERISE THE MICROSTRUCTURE OF THE POWDER?

  • Observe the morphology with a scanning electron microscope
  • Checking the chemical composition: elemental analysis (EDS, X-ray fluorescence), ICP
  • Identify the grain size distribution: screening, laser granulometer
  • Characterise flowability: Hall effect flowmeter, FreemanFT4
