Research on Printing Process Parameters of AlSi10Mg based on Printing Efficiency
The selective laser melting could effectively shape AlSi10Mg alloy,but the forming quality was closely related to the process parameters.On the premise of ensuring good strength and surface quality of the product,based on the print-ing process parameters of the same type of laser metal printing equipment,and by adjusting process parameters such as laser power,scanning spacing and so on,at the same time,using orthogonal experimental method to print samples for compara-tive testing.The filling printing process parameters were determined to be the laser power 430 W,the scanning speed 1 210 mm/s,the scanning spacing 0.19 mm,and contour printing process parameters were laser power 400 W,the scanning speed 500 mm/s.At this time,the tensile strength of the printed part was 407 MPa,the surface roughness Ra was 7.565 pm,and the printing efficiency was improved by about 21％.This provided a reference basis for the application of selective laser melting and forming technology of AlSi10Mg in actual production.
