Rapid prototyping is the process of quickly creating a physical model or assembly of a part using 3D computer aided design (CAD). This is typically done through additive manufacturing, more commonly known as 3D printing. Selective laser melting is a popular technique for achieving high-quality results. The fidelity of the prototype depends on how closely the design matches the final product. A high-fidelity prototype closely resembles the final product, while a low-fidelity prototype may have marked differences. Rapid prototyping allows for faster iteration and testing of designs, leading to more efficient and cost-effective product development.
