Compare 3D Printing Materials

Wax materials are a special type of material commonly used in 3D printing, primarily applied in rapid prototyping and precision casting. They offer excellent flowability and moldability, allowing for high-precision detail during the printing process. Red wax, in particular, has a vivid color, usually deep red, hence the name “red wax.” One of its key features is its ability to melt quickly when heated, facilitating subsequent casting processes, making it especially suitable for jewelry, art sculptures, and the manufacture of complex mechanical parts.

In addition, red wax materials have moderate hardness and a smooth surface, requiring minimal post-processing after printing, which helps maintain the accuracy and surface quality of the print. Because it can be melted at high temperatures, it is also commonly used in the “lost wax casting” process, playing a crucial role in precision casting.

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.
