| Abstract: |   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. |
