It enables rapid prototyping, by providing immediate visual hints about the structure of data.

Such models may include the "waterfall" model, rapid prototyping, or evolutionary development.

Paper prototyping is often used as the first step of rapid prototyping.

These innovations are often grouped under the rubric "rapid prototyping."

The major pros is the ease of development, specifically for rapid prototyping.

Q: I can understand its use in rapid prototyping, but what's another example?

Originally the rapid prototyping could only print using simple materials.

It is used for die casting and rapid prototyping.

This method has been used for rapid prototyping of structures with fine features.

However, some consider rapid prototyping to be a somewhat simplistic type of model.
