Rapid Prototyping vs Additive Manufacturing: A Comprehensive Guide
Introduction
Rapid prototyping and additive manufacturing are two transformative technologies that have revolutionized the manufacturing landscape. They enable the quick creation of prototypes and final products, respectively, using advanced techniques that significantly reduce production time and costs. This guide will delve into the differences, technical features, and various types of these technologies, providing insights into their applications and benefits.
Understanding Rapid Prototyping and Additive Manufacturing
Rapid prototyping refers to the process of quickly fabricating a physical model of a part or assembly using 3D CAD data. It allows designers to evaluate the design and functionality of a product before full-scale production. On the other hand, additive manufacturing encompasses a broader range of techniques that build objects layer by layer, often used for both prototyping and final product manufacturing.
