Electroless deposition of metal on 3D-printed polymeric structures

Patent ·
OSTI ID:1600352
A process for metallizing a three-dimensional-printed polymeric structure includes soaking the three-dimensional-printed polymeric structure in a metal salt solution; transferring the three-dimensional polymeric structure to a solution comprising a first reducing agent; soaking the three-dimensional polymeric structure in a metal plating bath, the metal plating bath comprising a coordinating agent, a palladium or platinum salt, a pH buffer component, and a second reducing agent, to form a metal plated polymeric structure. A metal plated porous structure and an apparatus for improving metallization are also disclosed.
