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.

PC-Like Advanced High Temp is a high-temperature reinforced material with properties similar to polycarbonate, specifically designed for functional parts that require a combination of high strength, stiffness, and heat resistance. Post-curing can further increase the heat deflection temperature of the parts, enhancing their stability and reliability in high-temperature environments. It should be noted that post-curing may reduce some aspects of durability, so a balance between strength and toughness should be considered during design.

PA+GF is a polyamide powder material reinforced with glass beads, which significantly improves stiffness and dimensional stability. Compared with unfilled polyamide, this material offers higher heat resistance and demonstrates excellent long-term wear performance. However, due to the addition of glass, its impact strength and tensile strength are relatively lower than those of other nylons.

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.
