Internal flow channel design for additive manufacturing: hydraulic and cooling channel optimization methods

Introduction: Internal flow channel design is the core advantage of additive manufacturing Traditional manufacturing processes are limited by tool accessibility and mold structure, making it difficult to achieve integrated manufacturing of complex internal flow channels. The emergence of 3D printing technology has completely changed this situation, allowing designers to freely arrange cooling channels, hydraulic channels and air channels inside the parts, greatly improving heat exchange efficiency, reducing flow resistance and reducing weight. However, internal flow channel design is not without constraints—support removal, powder cleaning, surface roughness, and pressure drop control are all factors that require careful consideration. This article will systematically introduce the internal flow channel design method for additive manufacturing to help workers...
