3D Printing AlSi10Mg - Aluminum-Magnesium Alloy

Metal DMLS 3D Printing Technical Parameters

  • 1. The maximum printing size of metal 3D printer: 250x250x325mm;

2. 3D printing layer thickness: 0.02mm~0.04mm;

  • 3. The achievable accuracy of 3D printing: Typical accuracy: ± 0.02-0.05 mm (Accuracy is related to geometry. It varies according to product size, printing direction, materials and post-processing methods.);
  • 4. Post-processing: high temperature annealing, polishing, welding and other processing;

3D Printing Material Characteristics

3D printing aluminum alloy AlSi10Mg is very suitable for combinations that require good thermal properties and low weight. They can be processed prototypes, spark erosion, welding, micro shot peening, polishing and electroplating.
