Hot Isostatic Pressing: Enhancing Additive Manufacturing Metal Properties
Received Date: Nov 03, 2025 / Published Date: Dec 01, 2025
Abstract
Hot Isostatic Pressing (HIP) is a vital post-processing technique for additively manufactured metal components, crucial for enhancing structural integrity and mechanical properties. HIP densifies parts by applying high temperature and isostatic gas pressure, effectively eliminating porosity and closing internal voids and microcracks. This process significantly improves tensile strength, yield strength, fatigue strength, ductility, and fracture toughness. Understanding microstructure evolution during HIP is key to optimizing parameters for desired material properties. HIP is indispensable for achieving full density in parts fabricated via powder metallurgy routes, including SLM and EBM, making them suitable for high-value applications in aerospace and medical sectors.
