1. VPMP Polytechnic Subject:- AMS Name:- VISHV PATEL Enrollment No: 2165403190 20 Branch:- Mechanical Semester:-5th Batch:-C 1 Tittle:- Identify various additive manufacturing process and system and prepare report.

2. What is Additive manufacturing (AM) process Additive manufacturing (AM) refers to a process by which digital 3D design data is used to build up a component in layers by depositing material. (from the internation committee F42 for additive manufacturing technologies, ASTM)...

3. Types of Additive manufacturing process:- Binder Jetting Direct Energy Deposition Material Extrusion Powder bed fusion Sheet Lamination Vat polymerisation Wire Arc Additive Manufacturing

4. 1) Binder Jetting :- The print head deposits the binder adheive on top of the powder where required. The build platform is lowered by the model’s layer thickness. Another layer of powder is spread over the previous layer. The object is formed where the powder is bound to the liquid.

5. (2) Direct Energy Deposition Additive manufacturing (AM) technologies produce three-dimensional (3D) physical objects from digital information through layer-by-layer, line-by-line, piece-by-piece, or surface-by-surface depositions of materials on the substrate and the previous layer. The AM is defined to be “a process of joining materials to make parts from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing and formative manufacturing methodologies”.

6. (3) Material Extrusion Extrusion is a compression process that creates the desired cross-sectional shape by forcing the work metal to flow through a die opening. It calls for the use of a wide range of substances, including .

7. (4) Powder bed fusion Powder bed fusion is defined as “an additive manufacturing process in which thermal energy selectively fuses regions of a powder bed.”

8. (5) Sheet Lamination Sheet lamination (SL) is the process where thin layers of materials, including paper, polymer, ceramic, metal, or composite laminates are bonded together layer-by-layer.

9. (6) Vat polymerisation Additive manufacturing, also known as 3D printing, is a disruptive manufacturing technology that gained vast interests both from academia and industry .

10. (7) Wire Arc Additive Manufacturing In the time of rapid industrial revolution, the need for enhanced engineering materials is continuously increasing, which is leading the modern world to the new, more efficient and faster manufacturing processes [1] The concept of Industry 4.0 is supported by nine pillars: cyber-physical systems, Internet of Things, Big data, 3D printing, robotics, simulation, augmented reality, cloud computing and cyber security [2] where, Additive Manufacturing (AM) integrates to a robust technique in manufacturing processes which is evolved from 3D printing [3], in AM the addition of two or more than two layers of similar or different materials are done.
