Abstract
A dip-coat binder solution comprises a dip-coat metallic precursor and a dip-coat binder. The dip-coat binder solution has a viscosity greater than or equal to 1 cP and less than or equal to 150 cP. A method of forming a part includes providing a green body part comprising a plurality of layers of print powder and a print binder, dipping the green body part in a dip-coat binder solution, and heating the dip-coated green body part. The dip-coated green body part is heated to form a coated green body part having a metallic precursor coating on an outer surface of the coated green body part. The coated green body part has a strength greater than or equal to 10 MPa.
Claims15
A method of forming a part, the method comprising:
