Final answer:
The three most common types of rapid prototyping are Fused Deposition Modeling (FDM), Stereolithography (SLA), and Selective Laser Sintering (SLS). Each technique has distinct advantages based on the desired material properties, complexity, and finish needed for the prototype.
Step-by-step explanation:
Rapid prototyping (RP) is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer-aided design (CAD) data. In the realm of engineering and product development, there are three common types of rapid prototyping technologies.
- Fused Deposition Modeling (FDM): This is an additive manufacturing process where material is deposited layer by layer to build the desired geometry. It uses thermoplastic materials and is widely known for its ease of use and clean operation.
- Stereolithography (SLA): This is one of the earliest RP techniques and works by curing photopolymer resin with an ultraviolet laser to form layers. SLA is renowned for its high resolution and surface finish.
- Selective Laser Sintering (SLS): In this method, a laser is used to sinter powdered material, bonding it together to create a solid structure. SLS does not require support structures and can produce parts with complex geometries.
Each of these methods serves distinct advantages, and the choice often depends on the required material properties, part complexity, and desired finish of the prototype.
