Original Abstract Submitted
a method of forming a build platform for a powder bed fusion additive manufacturing process. the method incudes directing a high-energy beam at a first energy level to irradiate a bed of fusible powder and to form a first layer of the build platform. the method also includes forming subsequent initial layers of the build platform, each subsequent layer being formed by directing the high-energy beam to irradiate a distributed layer of the fusible powder to form one of the subsequent initial layers of the build platform. the energy level of the high-energy beam is increased from the first energy level for successive layers of the subsequent initial layers. the build platform may be a sintered build platform where the degree of sintering increases from the bottom layer toward the top layer.
