Design Creation - Engineers use CAD (Computer-Aided Design) to create a 3D model. This digital blueprint defines the part’s specifications and geometry. Preparation & Printing - Preparation: Specialized software slices the model into layers and selects print parameters. Printing: Metal powder is melted or bound layer by layer, allowing complex designs.
