Understanding Additive Manufacturing
1. What is Additive Manufacturing?
- Additive Manufacturing refers to the process of creating three-dimensional objects by adding material layer by layer.
- It enables complex geometries and lightweight structures that are difficult to achieve with traditional methods.
2. Key Technologies in Additive Manufacturing
- Fused Deposition Modeling (FDM): Uses thermoplastic filaments to create prototypes and functional parts.
- Selective Laser Sintering (SLS): Utilizes laser technology to fuse powdered materials for durable components.
- Stereolithography (SLA): Cures liquid resin with UV light for high-detail parts.
- Metal 3D Printing (DMLS, EBM): Used for producing strong and lightweight metal parts in aerospace and automotive industries.
