Compare 3D Printing Materials

PEEK (Polyether Ether Ketone) is a high-performance engineering plastic widely used in aerospace, automotive, medical, and electronics industries. As a material that is resistant to high temperatures, chemical corrosion, and wear, PEEK offers exceptional strength and rigidity in 3D printing, making it suitable for demanding functional parts. It can withstand temperatures exceeding 250°C and maintain stable performance under high loads and extreme conditions. PEEK also has excellent electrical insulation properties and biocompatibility, making it an ideal choice for medical implants and high-end industrial components.

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.

Nylon is a high-performance engineering polymer with well-balanced properties. It offers high strength, excellent toughness, and outstanding wear resistance, along with superior chemical resistance and thermal stability, ensuring reliable performance even under demanding conditions. Thanks to its lightweight and high reliability, nylon materials are widely used in automotive, medical, aerospace, and consumer products, making them an ideal choice for applications requiring both functionality and durability.

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.
