Precision machining of micro-components is a vital manufacturing technology, widely used in sectors such as electronics, mechanical engineering, aerospace and the automotive industry. With technological advances and the market’s ever-increasing demand for high-precision, high-efficiency products, precision machining technology for micro-components is also continuing to evolve.

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.
