| Abstract Scope |
Hybrid Manufacturing optimizes the strengths of various processes while mitigating inherent limitations. Our multi-material hybrid manufacturing method integrates multi-material additive manufacturing with machining, hammering, and heat treatment. Wire Arc Additive Manufacturing (WAAM) uses an electric arc to melt and deposit metal wire layer by layer, creating a 3D-printed part. To address challenges like low accuracy and residual stress in WAAM, we incorporate conventional post-processing as an in-situ method. The multi-wire TIG-based WAAM system handles multi-material deposition. 5-axis machining improves dimensional accuracy and accommodates intricate shapes without support material, while pneumatic hammering introduces compressive stress to reduce residual stress and improve mechanical properties. An induction-based preheating system preheats the surface before deposition, reducing residual stress. This method enhances material processing, mechanical properties, and WAAM versatility for fabricating bimetallic, functionally gradient, and high-entropy alloy components. Success in multi-material WAAM relies on meticulous process optimization for specific materials, part geometry, and
desired properties. |
