  • Abstract

    Additive Manufacturing (AM), or 3D printing, is transforming the automotive industry by enabling the production of lightweight components without compromising strength or safety. Unlike traditional methods such as casting and machining, AM allows complex geometries, optimized lattice structures, and efficient material usage. This study reviews the use of AM for lightweight automotive parts, focusing on materials like ABS, PLA, Nylon, AlSi10Mg, Ti6Al4V, and carbon fiber composites. Advanced design techniques such as topology optimization and generative design are highlighted for maximizing weight reduction while maintaining performance. The research proposes a systematic approach involving CAD modeling, finite element analysis (FEA), process optimization, and manufacturing using FDM and SLM technologies. Evaluation methods include mechanical testing, microstructural analysis, and dimensional accuracy checks. Results indicate that AM components can achieve up to 40–60% weight reduction compared to conventional parts, with equal or improved mechanical properties. Additionally, life cycle assessment shows reduced material waste and energy consumption. However, challenges such as anisotropy, surface roughness, and certification issues remain. Future developments are expected in multi-material printing, AI-driven process control, and digital twin integration, positioning AM as a key technology for next-generation lightweight automotive design.
