What industry advantages does Inconel 718 have in additive manufacturing?

Oct 11, 2025

Inconel 718 has been a nickel superalloy and staple for industries that demand performance under extreme conditions, including aerospace, defense, energy, and oil and gas industries worldwide. As used in additive manufacturing, the technology which Enigma-DED (https://www.enigma-ded.com/) specializes in, Inconel 718 has even more potential for overcoming challenges in value-added manufacturing and offering unparalleled advantages in supply areas with extreme and additive manufacturing. Enigma-DED has ADDITIVE MANUFACTURING as a focal service because, as Intrastate acknowledges, traditional manufacturing processes face challenges in working with Inconel 718 due to its high strength and heat resistance. In contrast, additive manufacturing utilizes these characteristics to develop intricate and robust structures. Inconel 718 value in the industries adopting additive manufacturing as a practice reinforces its position as the material for installations which demand high reliability and performance.  

Inconel 718’s Perfect High-Temperature Resistance for Aerospace and Energy Industries  

In selective segments, as for aerospace and energy industries particularly, one of the most significant manufacturing advantages of Inconel 718 additive manufacturing is its amazing high-temperature resistance. Inconel 718 additive manufacturing keeps strength and structural integrity under extremes of 650 degrees centigrade which is more than enough for aircraft turbine blades, rocket engine parts, and even heat exchangers in energy power plants. To even more powder for value as Inconel 718 additive manufacturing, the yield of energy powder additive manufacturing allows complete control over the microstructure of Inconel 718 during the complete processes of additive manufacturing.

The employs sophisticated additive manufacturing techniques to improve the grain structure of inconel 718, keeping its heat resistance while improving ductility. In aerospace, for instance, additive-manufactured inconel 718 turbine components are lightweight and withstand intense heat of jet engines, which lowers fuel costs and enhances the efficiency of the aircraft. In the energy sector, components designed with additive manufacturing also inconel 718 withstands thermal fatigue in boilers of power plants which extend component lifespan and reduce downtime. This unique high-temperature inflexibility explains the heavy reliance on inconel 718 in industries with extreme thermal conditions.  

Inconel 718 Offers Unmatched Corrosion and Oxidation Resistance in Oil and Gas Industries  

In the oil and gas sector, the benefits of additive manufacturing of Inconel 718 are largely due to it's natural resistance to corrosion and oxidation. This is because of it's combination of nickel, chromium and molybdenum which form a protective layer that shields the alloy from damaging and aggressive oil and gas industry materials such as high pressured and salty water. Even traditional manufacturing techniques such as casting and forging, which are prone to defects such as microcracks or porosity which lead to corrosion, still maintain this resistance to corrosion. In this regard, Enigma-DED design engineered additive manufacturing to ensure the inconel 718 material has uniform density with minimal weak surfaces.

Additive-manufactured inconel 718 wellhead components can withstand the corrosive effects of oilfield brines and hydrogen sulfide for years, thus minimizing corrosion and the need for frequent replacements. In offshore applications, inconel 718 parts printed through additive manufacturing resist saltwater oxidation better than most other alloys, which helps reduce maintenance costs and improves the safety of operations. Inconel 718’s corrosion resistance confirms its reliability for oil and gas industries where constant environmental exposure impacts operations.  

Additive manufacturing drives the design of complex geometries, and inconel 718's compatibility with this process offers the defense and medical industries the opportunity to acquire custom components that are, most of the time, intricate and profoundly needed. Although creating complex shapes with inconel 718 using traditional methods is highly challenging, due to its strength and the partial design limitations that casting imposes during the manufacturing process, additive manufacturing mitigates this challenge. 

In the medical field, Additive-manufactured Inconel 718 can also be used as custom made orthopedic implants with custom made porous surfaces. These implants can also promote bone ingrowth. Inconel 718 is biocompatible and also has great strength and can be implanted for a long duration. For both the medical field and the aerospace industry, the ability to manufacture complex parts minimizes the number of components to be assembled, increasing the functional performance of each part. Design flexibility is crucial for specialized applications. Inconel 718 can be used for specialized applications in a number of industries.  

Inconel 718 Delivers High Strength to Weight Ratio for Innovations in the Automotive and Aerospace Sectors  

The strength to weight ratio of Inconel 718 becomes even more valuable in additive manufacturing which offers critical advantages in the automotive, particularly high performance and electric, and aerospace industries. Inconel 718 is stronger than many of the metals and is also lighter. This is important for the aerospace industry as it reduces parts weight without compromising on the strength. Additive manufacturing can further improve the strength to weight ratio. Inconel 718 can be designed with advanced hollow and lattice structures that help reduce weight while maintain Inconel 718's strength. 

Additive manufacturing of Inconel 718 turbocharger parts in high-performance automotive reduces total engine weight resulting in fuel saving and engine power improvements. For electric vehicles, even lighter Inconel 718 parts (for example Inconel parts for the battery cooling system) aids in range extension, since reduced weight also reduces the overall vehicle weight. The strength-to-weight advantage of Inconel 718 allows it to be key material for Inconel 718 industries that seek efficiency and performance. 

Inconel 718 for Long-Term Durability and Fatigue Resistance in Critical Industrial Applications

In power generation, defense, and aerospace, Inconel 718, durably constructed through additive manufacturing, prevents catastrophic errors and costly downtimes. Inconel 718 withstands cyclic fatigue, the repeated and constant stress of a turbine and internal impacts, without cracking. For example, in the aerospace industry, Additive manufacturing Inconel 718 power turbine rotors under cyclic stress and serves decades longer than the cast parts. In defense, Additive manufacturing Inconel 718 missile parts withstand launch and in-flight fatigue, for reliable performance in critical missions.

Inconel 718's long-lasting properties also imply that parts made using additive manufacturing need less upkeep and less frequent replacements, which reduces costs over time for businesses. Because of this ongoing reliability, Inconel 718 is invaluable for use in applications where failure is unacceptable.
