[Abstract] The detection and correction of deformation in the main girder of bridge (gantry) cranes is a common issue faced by enterprises in their production processes. This paper outlines several methods for detecting and correcting such deformation, describes their characteristics, and explains their scope of application. Keywords: main girder deformation, detection, correction

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.
