This assignment, prepared for an Introduction to Manufacturing Processes course (EBMM2103), comprehensively explores casting processes, casting defects, and emerging engineering materials. The first part of the assignment delves into the history of casting, various types of casting methods like investment, centrifugal, die, and sand casting, along with their respective advantages, disadvantages, and applications. It also provides a detailed analysis of common casting defects, including metallurgical defects, pouring metal defects, gas porosity, and shrinkage defects, along with relevant quality test methods. The second part focuses on emerging engineering materials, specifically biomaterials, examining their characteristics such as biocompatibility, self-assembly, and bioactivity, along with their fabrication processes and mechanical and chemical properties like stiffness, strength, and durability. The assignment provides a comprehensive overview of casting processes and biomaterials, offering a valuable resource for students studying manufacturing processes.
