HIP and Additive Manufacturing
Hot Isostatic Pressing (HIP) has been used successfully by manufacturers around the world. HIP is used to eliminate pores and remove defects, i.e. nitrides, oxides and carbides, to dramatically increase the material properties.
With typical pressures from 400 to 2,070 bar (5,800 to 30,000 psi) and temperatures up to 2,000°C (3,632°F), HIP can achieve 100% of maximum theoretical density and improve the ductility and fatigue resistance of critical, high-performance materials. The components from 3D-printing, regardless of method (EBM, SLM, etc.), benefits greatly from HIPing.
