Answer:
rapid prototyping
Step-by-step explanation:
Rapid prototyping (RP) is a family of manufacturing methods to make engineering prototypes in the minimum possible delivery times, based on a model of the article made in a computer-aided design system (CAD)
Rapid prototyping is an excellent way to check the functionality, dimensions and design characteristics of the designs, without going through the usual long prototyping process that requires specific technical and experienced tools.
