;ciencg Solid Freeform Fabrication Using Semi-Solid Processing

A proof-of-concept prototype has been developed to demonstrate the feasibility of solid freeform fabrication using semi-solid metals. A model system of 85 % Sn-15 % Pb slurry was used to generate 3-dimensional components in a freeform fabrication process. These components are near net shape and possess advantages over other methods of manufacture. The components are metal, fully dense, and produced quickly. Immediate application in rapid prototyping is evidenced, as well as potential for cost-effective small
