3D Systems LaserForm® Maraging Steel (A), AGING 2
Categories:	Metal; Ferrous Metal; Stainless Steel
Material Notes:	Maraging steel fine-tuned for use with ProX® DMP 320 metal 3D printers to produce industrial parts and tool inserts with a combination of high strength and excellent hardness. LaserForm Maraging Steel (A) is formulated and fine-tuned specifically for 3D Systems DMP 320 metal 3D Printers to deliver highest part quality and best part properties. With properties like 1.2709, this steel is easily heat-treatable in a simple age-hardening process resulting in excellent hardness and strength. LaserForm Maraging Steel (A) has good wear resistance. In regards to post-processing, the material shows good weldability and machinability. LaserForm Maraging Steel (A) is ideal for innovative tool and mold designs including conformal cooling channels for injection molding, die casting and extrusion. The material is also used for high-performance aerospace, automotive and other industrial applications which require high strength and wear resistance. Classification: Parts built with LaserForm Maraging Steel (A) have a chemical composition that conforms to the compositional requirements of Werkstoff Nr. 1.2709. Information provided by 3D Systems
