Rapid 3D prototyping is primarily supported by additive manufacturing modes, including Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS). These methods build 3D models layer by layer from digital files, avoiding complex tooling and shortening prototype development cycles.
- FDM: Extrudes thermoplastic filaments layer by layer, cost-effective and widely used for basic functional prototypes. - SLA: Uses UV laser to cure liquid resin, offering high precision and smooth surface finishes, suitable for detailed parts. - SLS: Sinters powdered materials (e.g., nylon) with a laser, producing strong, durable prototypes with complex geometries.
These modes streamline prototyping by reducing lead times and tooling costs, making them core choices for rapid 3D prototyping.
