Multi-material tooling and methods of making same

Abstract

Multi-material tooling and methods of making multi-material tooling are provided. The multi-material tooling includes a core formed of a first material having a hardness (Rockwell C scale) of up to 30 HRC, and a shell layer adjacent to the core. The shell layer is formed of a second material having a hardness of 33 HRC to 70 HRC. The method of making multi-material includes depositing a first layer of a first material using an additive manufacturing technique to form a core. The first material that forms the core has a hardness of up to 30 HRC. The method also includes depositing a second layer of a second material to form a shell layer adjacent to the core. The second material that forms the shell layer has a hardness of 33 HRC to 70 HRC.
