Abstract: This study focuses on the modeling and 3D printing of an industrial gearbox to explore the feasibility of using additive manufacturing for prototyping and educational purposes. A detailed 3D CAD model of a standard industrial gearbox was developed using SolidWorks, incorporating key mechanical components such as gears, shafts, bearings, and housing. The model was analyzed for dimensional accuracy and assembly compatibility. Fused Deposition Modeling (FDM) 3D printing technology was used to fabricate the physical prototype using PLA material. The printed model was evaluated for geometric precision, ease of assembly, and visualization of internal gear mechanisms. This project demonstrates the effectiveness of 3D printing for producing cost-effective and functional scale models for design verification and demonstration applications.
