3D Systems LaserForm® AlSi10Mg (A), DIRECT AGING Aluminum Alloy Material
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Aluminum Alloy
Material Notes:	AlSi10Mg fine-tuned for use with ProX® DMP 320 metal printer producing industrial parts with a combination of good mechanical properties and good thermal conductivity. LaserForm AlSi10Mg (A) is formulated and fine-tuned specifically for 3D Systems DMP 320 metal 3D Printers to deliver high part quality and consistent part properties. AlSi10Mg combines silicon and magnesium as alloying elements, which results in a significant increase in strength and hardness compared to other aluminum alloys. Due to the very rapid melting and solidification during Direct Metal Printing, LaserForm AlSi10Mg (A) in as-printed condition shows fine microstructure and high strengths. In the aerospace and automotive industry, LaserForm AlSi10Mg (A) is used for its light weight. Both innovative approaches to mold design and specific heat exchanger applications make use of the high thermal conductivity of this alloy. Information provided by 3D Systems
