HIP Supporting 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.

Hot Isostatic Pressing for AM parts

by Dr. Johan Hjärne, Global Business Development and Magnus Ahlfors, Applications Engineer
For critical components in high demanding applications produced by powder based additive manufacturing, Hot Isostatic Pressing (HIP) plays an important role to assure and increase the quality of the produced parts.

High Pressure Heat Treatment perfects the properties of your medical implants

by Dr. Johan Hjärne
Pioneering developments from Quintus Technologies allow stress relieving, HIP, and quenching to be applied in the same press, an innovation with significant implications for cost and quality. Not only does this approach drastically lower post-processing costs, but it can also break up columnar grain structures for 3D printed medical implants.

Phase Transformation Under Isostatic Pressure in HIP

HIP Supporting 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.

High Pressure Heat Treatment of PM Parts by Hot Isostatic Pressing

Hot Isostatic Pressing (HIP) is a proven technology that has been developed and refined for over 60 years. By combining high temperature and high gas pressure, metal and ceramic powders can be consolidated and a volume decrease can be achieved.

Why you should HIP
100% of theoretical density
  • Longer life time
  • Predictive life time
  • Lighter and/or low weight designs
Improved material properties
  • Increased mechanical properties e.g. fatigue, wear, abrasion and ductility
  • Reduced property scatter
  • Stress relief of AM parts
More efficient production vs. traditional manufacturing
  • AM combined with HIP can reduce energy use up to 50%
  • AM combined with HIP can reduce material costs up to 90%

HIP and Heat Treatment simultaneously

Quintus Uniform Rapid Cooling (URC™) and optional Uniform Rapid Quenching (URQ™) furnaces can provide decreased cycle time, higher productivity, and a unique HIP cycle that includes heat treatment. Benefits are reduced energy consumption, reduced costs, improved quality control and the material is ready for following production steps, i.e machining, polishing, etc.

Pore elimination gives dramatic effects of the fatigue life when it comes to stress levels and number of cycles before failure. Up to 10 times improvement can be achieved by HIPing in the right conditions.

Post treatment

By applying the right conditions in the HIP, post-treatment steps like in a stress relief furnace, the total cycle times can be shortened by 50%.

A proven process for additive manufacturing parts

Common applications for hot isostatic pressing include defect healing of AM parts (pore elimination), consolidation of Titanium powder and diffusion bonding of dissimilar metals or alloys. The technology is expanding into new applications for aerospace applications as well as heat treatment.

Improving parts for the aerospace industry

Of all the HIP installations in the world, more than 50% are utilized to consolidate and improve the material properties of Titanium and Superalloys for the aerospace industry. Today HIP is the standard procedure to give longer and predictive life time of fan blades in an aircraft engine.

Regardless of alloy system, or 3D printing method (EBM, SLM, etc.), HIP is the way forward for optimized material properties and cost savings for safe and efficient production with high quality.

HIP Quenching Values
Controlled cooling rates up to 3,000°C/min can be achieved by combining possibilities of pressure and temperature control that the URQ can offer:
  • Heat treatment steps can be included into the HIP cycle
  • Shortened lead time
  • Process steps, like stress relief, can be removed from the usual process route to increase productivity and lower cost/kg
Benefits compared to conventional heat treatment methods:
  • Programmable temperature distribution with good accuracy
  • No distortion due to reduced thermal stresses
  • No cleaning or drying of parts after quenching
  • Reduced cracking
New and unique materials can be achieved
  • Material optimization
  • Improved fatigue and ductility
  • Non-castable alloy compositions
