Abstract: The advancement of additive manufacturing has revolutionized the prototyping and fabrication of complex mechanical systems, including internal combustion engines. This study focuses on the design, Modelling, and 3D printing of a four-cylinder engine block, replicating its structural and functional features with high precision. Computer-Aided Design (CAD) software was employed to create detailed component models, ensuring accurate dimensions, proper assembly compatibility, and functional motion. The fabrication process utilized Fused Deposition Modelling (FDM) technology with high-strength thermoplastic materials to optimize durability, surface finish, and mechanical reliability. Post-processing steps such as sanding, support removal, and alignment adjustments were performed to enhance assembly quality and functional performance. The printed parts were subsequently assembled to evaluate fit, movement, and potential real-world applicability. This project demonstrates the feasibility of using 3D printing for educational models, mechanical design validation, and rapid prototyping. Additionally, it underscores the utility of 3D-printed engine models as effective tools in academic environments for teaching engine dynamics, kinematics, and thermodynamic concepts. Key Words: 3D Printing, Four-Cylinder Engine, CAD Modelling, Additive Manufacturing, Rapid Prototyping, FDM Technology, Mechanical Assembly, Engine Design, Prototyping.
