addictive manufacture

1. Additive Manufacturing (AM) – Definition Additive Manufacturing is a process of creating three-dimensional (3D) objects by adding material layer by layer, based on digital 3D models (usually CAD). It is often called 3D printing and contrasts with traditional subtractive manufacturing, where material is removed from a solid block (e.g., milling, turning). --- 2. Classification of Additive Manufacturing According to ISO/ASTM 52900, AM processes are classified into seven main categories: No Category Example Process 1 Material Extrusion FDM (Fused Deposition Modeling) 2 Vat Photopolymerization SLA (Stereolithography) 3 Binder Jetting Jet Binder Printing 4 Material Jetting PolyJet 5 Powder Bed Fusion SLS (Selective Laser Sintering), SLM 6 Sheet Lamination LOM (Laminated Object Manufacturing) 7 Directed Energy Deposition DED, Laser Metal Deposition --- 3. Pre-Processing, Processing, and Post-Processing Let’s discuss each process: --- A. FDM (Fused Deposition Modeling) Category: Material E...
