Understanding Reverse Engineering — Lesson 2

This lesson covers the intricate process of reverse engineering in metal additive manufacturing. It delves into the methodology and stages involved in reverse engineering, including data acquisition, alignment, mesh generation, post-processing, and simplification. The lesson also discusses different types of 3D scanners, such as laser and structured light scanners, and their applications. It further explores the legality and justifications for reverse engineering, including interfacing, obsolescence, security analysis, and competitive technical intelligence. The lesson concludes with a practical assignment for learners to dismantle a product and understand its components, thereby gaining a hands-on understanding of reverse engineering.
