| Abstract: |
| Additive manufacturing (AM) or 3D printing of metals promises a significant impact to the upcoming industrial revolution “Industry 4.0” as it considered one of its main pillars. However, some challenges related to high initial cost and the fabricated part’s quality still existed. Selective laser melting (SLM) is one of the effective techniques used for additive manufacturing to fabricate metal products. This paper presents the impact of different post-processing treatment on the microstructure and surface quality of the AlSi10Mg parts fabricated using SLM. A process map is developed for thermal post-processing treatment to customize the required quality and material characteristics of the AlSi10Mg parts. In addition, the shot peening impact on both surface roughness and hardness is illustrated. This work is a part of developing the manufacturing process of additively manufactured lightweight parts in some critical applications specifically for the metallic mirrors used in high power laser systems or wide view space telescopes. |
