Research on Forming Quality of AlSi10Mg Powder for SLM Process

Abstract:

In order to study the forming quality of AlSi10Mg powder for SLM process without supporting structure, as well as lay the foundation of subsequence structural design of Aluminum SLM technique, a series of typical coupons have been designed and printed. Based on comprehensive consideration of layout direction, overhang angle, hole size, etc., Xline 2000R with optimized process parameter has been used as SLM equipment for AlSi10Mg powder. Through the analysis of printed coupons, the beneficial conclusion is made which can be used to guide future design, especially for the structure with complex shape.
