Types of Rapid Prototyping
Rapid prototyping can be categorized based on the technology used and the fidelity of the prototypes produced. Below is a comparison table of different types of rapid prototyping methods:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Stereolithography (SLA) | Uses UV light to cure resin into solid parts. | High accuracy, smooth surface finish. | Limited to resin materials, weaker parts. |
| Selective Laser Sintering (SLS) | Uses a laser to sinter powdered material into solid parts. | No support structures needed, good for complex shapes. | Rough surface finish, limited material options. |
| Fused Deposition Modeling (FDM) | Extrudes thermoplastic filaments to build parts layer by layer. | Cost-effective, widely available materials. | Lower surface finish quality, slower than others. |
| Multi Jet Fusion (MJF) | Uses a fusing agent to bond powder and create parts. | Fast production, excellent mechanical properties. | Limited to specific materials, higher costs. |
| Direct Metal Laser Sintering (DMLS) | Melts metal powder to create dense parts. | Strong, complex geometries possible. | Expensive, requires post-processing. |
