Introduction
Additive Manufacturing (AM) technology has brought numerous benefits to mankind and considering the benefits of the technology such as manufacturing of complex shapes and lightweight parts, easy customization, design freedom, etc., it is expected that this technology will be a more vital part of the manufacturing processes in the coming years. Even this technology has found its place in many industries and it’s regularly used nowadays, there are still areas where additive manufacturing cannot be applied because of certain limitations. These limitations are not allowing additive manufacturing to be used for critical parts, either because of technical or safety reasons. By employing Laser Shock Peening (LSP), many of these limitations can be overcome, mitigated, or even completely eliminated. Laser Shock Peening can significantly improve the mechanical properties of the AM parts and bring AM technology into the most demanding applications and industries.
Objectives
In this article, we will present how LSP improves mechanical properties of the AM, such as surface roughness, surface integrity, fatigue life, and how the microstructure is refined by LSP for different types of metallic alloys.
