Solid State-Based AM Processes
Solid state-based additive manufacturing processes, including Fused Deposition Modeling (FDM), Laminated Object Manufacturing (LOM), and other techniques, utilize different materials and methods for creating complex geometries. FDM relies on thermoplastic filaments, while LOM employs adhesive-coated sheets. Each process has unique advantages and limitations, making them suitable for specific applications ranging from prototyping to end-use parts in various industries.

What we have learnt
- FDM is a widely used material extrusion technique suitable for creating complex shapes using thermoplastic materials.
- LOM combines layers of adhesive-coated sheets and cutting techniques for rapid prototyping with low costs.
- Other solid-state AM processes like ultrasonic consolidation provide unique capabilities for bonding metals without melting.
Key Concepts
- -- Fused Deposition Modeling (FDM)
- A material extrusion process where thermoplastic filament is melted and layered to form 3D structures.
- -- Laminated Object Manufacturing (LOM)
- A process that uses sheets of adhesive-coated material which are bonded and cut to create layers of a part.
- -- Ultrasonic Consolidation (UC)
- A solid-state welding technique that uses ultrasonic vibrations to bond metal foils without melting.
