Abstract

Model of 3D-printed component Superalloys exhibit great strength and corrosion resistance even when subjected to high heat and stress, making them especially suitable for challenging applications such as aerospace, automotive, and chemical. However, so far it has been difficult to use nonweldable materials such as MAR M247 in 3D printing, to which high solidification rates and thermal gradients are inherent. Digital Metal’s unique binder jetting technology helps avoid this problem by printing at an ambient temperature without applying any heat, and then performing a separate sintering step. During sintering, densification occurs without melting and with minimal thermal gradients during cooling from the sintering temperature. DM 247 is based on the nonweldable MAR M247, which is widely used as material for turbine blades and in other applications with elevated temperatures. DM 625 is an Inconel 625 grade. Its application areas range from seawater applications and chemical processing equipment to nuclear industry and aerospace. For more information: www.digitalmetal.tech.
