Der Leitfaden für den 3D-Druck mit Inconel

Alles, was Sie über die Nickelbasislegierung wissen müssen.

Inconel, a high-performance superalloy, is widely used in industries that demand exceptional strength, heat resistance, and corrosion protection.

Inconel 625 and Inconel 718 have become popular choices for producing intricate, durable components through Laser-Pulver-Bett-Fusion (LPBF). This guide covers the advantages, material options, and key post-processing techniques for 3D printing Inconel.

Advantages of Inconel 3D Printing

Inconel 3D printing offers several benefits, particularly for industries requiring high performance in extreme environments.

High-temperature resistance: Inconel’s ability to withstand extreme temperatures makes it ideal for engine components, turbines, and other high-heat applications.

Corrosion resistance: Inconel’s remarkable resistance to oxidation and corrosion is critical for harsh environments like chemical plants, marine applications, and gas turbines.

Komplexe Geometrien: LPBF allows for intricate designs, such as cooling channels or lattice structures, that are difficult or impossible to achieve with traditional manufacturing methods.

Material efficiency: 3D printing uses only the material needed for the part, minimizing waste and reducing material costs.

Faster lead times: 3D printing accelerates the production process without complex tooling, making it ideal for prototyping and low-volume production.

Common Materials for Inconel 3D Printing

Inconel comes in several alloy compositions, but Inconel 625 and Inconel 718 are the most used on the MakerVerse platform.

Inconel 625

Inconel 625 (IN625) ist eine Nichteisenlegierung auf Nickelbasis, die sich durch eine gute Leistung in Hochtemperaturumgebungen mit besonderer Widerstandsfähigkeit gegen Oxidation auszeichnet. Dies liegt hauptsächlich daran, dass IN625 weniger Eisen und einen höheren Chromgehalt als andere Legierungen aufweist. Darüber hinaus ist IN625 in der Lage, hohe Temperaturen zu ertragen, ähnlich wie andere Nickel-Superlegierungen.

Inconel 625 PropertiesWert
Streckgrenze Rp 0.2%630-690 MPa
Höchstzugkraft Rm850-950 MPa
Dehnung beim Bruch29-39%
Elastizitätsmodul170-230 GPa
Relative Dichte>99.5%

Inconel 625’s combination of corrosion resistance and high strength allows it to perform well in demanding conditions, particularly in saltwater and chemical environments.

Nickel-Chromlegierung

Inconel 718 (IN718) is a nickel-based superalloy with good performance in high-temperature environments. This is mainly because IN718 has good mechanical properties up to 700 °C. Furthermore, the metal has excellent oxidation and corrosion resistance, making it ideal for use in demanding environments. Another advantage is the high strength of the material.

EigentumWert
Yield Strength Rp 0.2% [MPa]560-770
Ultimate Tensile Strength Rm [MPa]870-1050
Elongation at Break [%]22-32%
Young’s Modulus [GPa]150-188
Hardness47 HRc


Inconel 718 is particularly valuable for its ability to retain strength at high temperatures, making it a top choice for applications that endure extreme heat and stress.

Post-Processing Techniques for Inconel 3D Printing

Post-processing is a crucial step in enhancing the mechanical properties, durability, and surface finish of Inconel parts. These are the most commonly used post-processing techniques for Inconel 625 and Inconel 718 on the MakerVerse platform.

Wärmebehandlung: Heat treatment is vital in improving Inconel’s mechanical properties. This process enhances strength and high-temperature performance by precipitating hardening phases. Heat treatment can also improve overall stress resistance, making parts more durable in demanding environments.

Poliert: Polishing is essential for achieving a smooth, reflective surface on Inconel parts. This is particularly important for components in high-wear applications, such as turbine blades or engine parts, where surface finish affects performance.

Tumbled: Tumbling is a process that smooths out rough surfaces and removes sharp edges from complex geometries. It is especially useful for parts with intricate designs or internal channels, ensuring a uniform, matte finish throughout.

Gemalt: Painting Inconel parts adds a protective layer that  improves aesthetic appeal. This is especially beneficial for consumer-facing products.

CNC machined: CNC machining is often used to fine-tune 3D-printed Inconel parts, ensuring precision in critical areas like holes, threads, and tight tolerances. It provides the exact dimensions and smooth surfaces required for high-performance applications, especially in aerospace or medical industries.
