Abstract: A method of making a pre-sintered preform, including forming a pre-sintered preform by a binder jet additive manufacturing technique. The binder jet additive manufacturing technique includes depositing a first powder layer including a first powder and a second powder followed by depositing a first binder at a pre-determined location of the first powder layer. The binder jet additive manufacturing technique also includes depositing a second powder layer over at least a portion of the first powder layer followed by depositing a second binder at a pre-determined location of the second powder layer. At least a portion of the first binder and at least a portion of the second binder is cured forming a green part. The green part is then densified to form a pre-sintered preform near net shape component.
