2D profile-based surface repair and 3D pattern generative design via material jetting

Abstract

Jetting printing processes rely on 2D pixel data derived from decomposed 3D models, which are often unavailable in applications such as surface repair and 3D pattern printing. Reconstructing 3D models and decomposing them into 2D pixels is time-consuming, energy-intensive, and prone to accuracy loss. This paper introduces a novel 2D profile-based design and control method, using 2D contour curves to generate precise pixels for jetting 3D volumes. This approach enhances efficiency, accuracy, and agility while reducing costs. Case studies on surface repair and 3D pattern printing validate its feasibility, with potential applications in multi-axis robotic systems and functional surface formation.
