Rapid prototyping encompasses various techniques to quickly create scale models of a part or product, often using 3D computer-aided design (CAD) data. Here are four different types:1. Stereolithography (SLA):
Description: SLA is one of the earliest forms of 3D printing. It uses a laser to cure liquid resin into hardened plastic in a layer-by-layer process.
Advantages: High precision, smooth surface finishes, and suitable for complex geometries.
Applications: Functional prototypes, molds, medical models, and high-detail parts.
2. Selective Laser Sintering (SLS):
Description: SLS uses a laser to fuse powdered material (usually nylon or polyamide) layer by layer to create a solid structure.
Advantages: Strong and durable parts, no need for support structures, and suitable for a variety of materials.
Applications: Functional prototypes, end-use parts, and parts with complex geometries.
3. Fused Deposition Modeling (FDM):
Description: FDM works by extruding thermoplastic filaments through a heated nozzle, layer by layer, to build up the part.
Advantages: Cost-effective, easy to use, and suitable for a wide range of materials including ABS, PLA, and PETG.
Applications: Prototypes for form and fit testing, concept models, and educational purposes.
4. Digital Light Processing (DLP):
Description: DLP is similar to SLA but uses a digital light projector to cure the resin. It can cure entire layers at once, making it faster than SLA.
Advantages: High resolution, fast build times, and good for fine details.
Applications: Dental models, jewelry, small parts with fine details, and intricate designs.
