METALLIC STRUCTURE |
摘要 |
A method of casting a truss structure having spaced face sheets connected by columnar structures, including forming a three-dimensional pattern (3D pattern) in the shape of the truss structure with the spaced face sheets and columnar structures, forming a mold core of the 3D pattern by surrounding the pattern with a liquid and letting the liquid harden about the 3D pattern, removing the 3D pattern from the mold core, filling the mold core with a liquid alloy to cast and directionally solidify the truss structure. |
