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.

17-4 PH stainless steel is a precipitation-hardening stainless steel known for its excellent hardness and corrosion resistance. Through vacuum solution heat treatment and H900 aging treatment, printed parts can achieve high strength, high hardness, and good wear resistance. 17-4 PH stainless steel is suitable for manufacturing industrial components that require high strength, corrosion resistance, and complex structures, such as aerospace parts, molds, and high-load machinery.
Disadvantages: Low elongation (≤16% after heat treatment); weak magnetism after heat treatment.

TPU is a flexible and highly tough filament with excellent impact resistance and wear resistance. It is suitable for printing various production prototypes and functional parts that need to withstand impact, drops, and collisions.
