Rapid Prototyping – Definition, Examples, History & More – Digital Art and Technology Glossary

What is Rapid Prototyping?

Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using 3D computer-aided design (CAD) data. It allows for the quick and cost-effective creation of prototypes for testing, evaluation, and feedback before final production.

Rapid prototyping techniques involve additive manufacturing processes, where material is added layer by layer to create the final product. This allows for complex geometries and intricate designs to be produced with ease.

Types of Rapid Prototyping Technologies

1. Stereolithography (SLA): This technology uses a UV laser to solidify liquid resin layer by layer to create a 3D object.

2. Selective Laser Sintering (SLS): In this process, a laser is used to sinter powdered material, such as nylon or metal, to create a solid object.

3. Fused Deposition Modeling (FDM): FDM involves extruding thermoplastic material through a nozzle to build up layers and create a 3D object.

4. Digital Light Processing (DLP): DLP uses a projector to cure liquid resin layer by layer to create a 3D object.

Advantages of Rapid Prototyping

– Speed: Rapid prototyping allows for quick turnaround times, reducing the time it takes to go from design to physical prototype.
– Cost-effective: By eliminating the need for expensive molds or tooling, rapid prototyping can save companies money during the product development process.
– Iterative design: Rapid prototyping enables designers to quickly make changes and improvements to their designs based on feedback from testing and evaluation.
– Customization: With rapid prototyping, it is easy to create customized parts or products tailored to specific needs or requirements.
