Final answer:

Heat treatment is the primary AM post-processing technique for enhancing metal part properties like hardness and strength.


Explanation:

Heat treatment is the AM post-processing technique used to improve the physical and mechanical properties of metal parts. This process involves heating the metal to specific temperatures and then cooling it in a controlled manner to alter its properties.

During heat treatment, the metal undergoes changes in structure that can enhance its hardness, toughness, and strength. For example, annealing can reduce internal stresses in the metal, while quenching can increase its hardness.

Electropolishing is another technique mentioned, but it is primarily used for preparing thin films of metals and alloys, not for improving physical and mechanical properties.
