3D Systems LaserForm® AlSi12 (B), AS-BUILT Aluminum Alloy Material
Categories:	Metal; Ferrous Metal; Stainless Steel
Material Notes:	LaserForm AlSi12 (B) is formulated and fine-tuned specifically for 3D Systems’ ProX® DMP 200 and 300 metal 3D printers to deliver highest part quality and best part properties. Known for its high strength–to-weight ratio and good thermal properties, the lightweight Laserform AlSi12 (B) is frequently used in aerospace, aviation, motorsports and automotive applications as well as for specifically thin-walled applications such as the production of heat exchangers. With Direct Metal Printing, parts that were typically cast are now being directly printed. Even more complex designs than typical casting processes allow can be produced in one single piece using DMP. Classification: The chemical composition of LaserForm AlSi12 (B) conforms to the requirements of ISO 18273, ISO 17672, UNS A94047 and DIN EN 1706 specifications. Information provided by 3D Systems
