Patent ID: 10040242

Abstract:
A method comprising depositing, in layers, a shrinking platform formed from a composite including metal particles embedded in a first matrix, depositing shrinking supports of the composite upon the shrinking platform, forming a separation clearance dividing at least one shrinking support into fragments, depositing, from the composite, a part upon the shrinking platform and shrinking supports, depositing a separation material intervening between the part and the shrinking supports, the separation material including a ceramic powder and a second matrix, and forming, from the shrinking platform, shrinking supports, separation material, and part, a portable platform assembly in a green state, wherein the shrinking support is configured to prevent the portable platform assembly from distorting from gravitational force during sintering of the metal particles of the assembly in a brown state, and wherein the ceramic powder of the separation material is configured to separate the shrinking support from the part following sintering.
