Compare 3D Printing Materials

Inconel 718 is known for its outstanding high-temperature strength, creep resistance, and corrosion resistance. The material can withstand operating temperatures above 700°C while maintaining excellent fatigue and fracture resistance. Through additive manufacturing, GH4169 can produce parts with complex geometries and is widely used in aerospace engines, gas turbines, high-temperature molds, and high-performance industrial components.
Disadvantages: High cost; complex heat treatment process; thin-walled structures require careful design; default surface roughness Ra10–12.

3D printed titanium alloys, represented by Ti6Al4V, feature extremely high specific strength and excellent corrosion resistance, while being lightweight and tough. They enable the creation of complex geometries and topology-optimized designs through additive manufacturing, and are widely used in aerospace, medical implants, automotive, and high-performance sports equipment. Titanium alloys also offer good high-temperature performance and biocompatibility, making them an ideal choice for manufacturing high-performance, lightweight components.
Disadvantages: Poor heat resistance (maximum 120°C); surface roughness around Ra10, with slight pits and visible layer texture.

Stainless steel 316L offers excellent corrosion resistance and high-temperature performance. It combines good mechanical strength and toughness, making it a reliable material for manufacturing acid- and corrosion-resistant components. Thanks to its outstanding corrosion resistance and its suitability as a medical- and food-grade material, it is widely used in aerospace, prototypes, tooling, and medical applications. Finished parts are typically shot-peened for surface treatment. If you require any other post-processing, please inform our customer service clearly.
Disadvantages: Poor heat resistance (maximum 120°C); surface roughness around Ra10, with slight pits and visible layer texture.
