Following decades of development, prototype manufacturing has evolved into three core process systems centred on CNC precision machining, 3D printing rapid prototyping and vacuum casting. This article will examine these systems from four key perspectives: process principles, strengths and weaknesses, material suitability, and application scenarios.
