  In the world of  CNC rapid prototyping , material selection is one of the most critical decisions in the development process. The material used not only affects the prototype’s strength, durability, and thermal behavior but also impacts machining efficiency, cost, and overall project timeline. For engineers and product designers, understanding the properties of metals and plastics used in CNC prototyping is essential to ensure that prototypes accurately represent final production parts. This comprehensive materials guide explores the most common metals and plastics used in CNC rapid prototyping, their advantages, limitations, and best applications, helping manufacturers make informed decisions that balance cost, performance, and functionality. ​ Why Material Selection Matters in CNC Rapid Prototyping Choosing the right material is not just about matching the final product—it also affects: Prototype Accuracy: Ensures functional, thermal, and mechanical behavior closely r...
