Patent attributes
To reduce distortion in an additively manufactured part, a shrinking platform is formed from a metal particulate filler in a debindable matrix. Shrinking supports of the same material are formed above the shrinking platform, and a desired part of the same material is formed upon them. A sliding release layer is provided below the shrinking platform of equal or larger surface area than a bottom of the shrinking platform to lateral resistance between the shrinking platform and an underlying surface. The matrix is debound sufficient to form a shape-retaining brown part assembly including the shrinking platform, shrinking supports, and the desired part. The shape-retaining brown part assembly is heated to shrink all of the components together at a same rate via atomic diffusion.
