Rapid prototyping is a technology which enables the quick and cost-effective creation of physical models, prototypes, or parts using additive manufacturing techniques. This process involves layer-by-layer construction of the prototype directly from a digital 3D model, allowing for rapid iteration and design modifications. Rapid prototyping is commonly used in various industries such as automotive, aerospace, healthcare, and consumer goods to test and validate designs before mass production. It helps to reduce time-to-market, improve product quality, and lower development costs.
