Our Threaded Inserts for 3D Printed Parts are precision-engineered fastening solutions designed to create strong, reusable threads in 3D-printed components. Made from premium Materials such as brass, stainless Steel, and aluminum alloy, these inserts ensure excellent thread retention and long-lasting performance.
Each threaded insert for 3D printing features a knurled or helical outer design that provides exceptional grip within thermoplastics like PLA, ABS, PETG, and Nylon. Our heat set threaded inserts can be easily installed using a soldering iron or ultrasonic welder, forming a durable and high-torque connection that outperforms traditional self-tapping screws.
We offer custom threaded inserts in a wide range of sizes—including M2, M3, M4, and M5 threaded inserts for 3D printed parts—with options for different knurl patterns, flange styles, and finishes.

High Precision: CNC-machined to tight tolerances for smooth threading and consistent fit.
Multiple Sizes & Styles: Available in M3, M4, M5, and other metric or inch sizes for all 3D printing needs.
Excellent Grip Design: Deep knurled patterns and tapered ends enhance anchoring strength in plastic materials.
Material Versatility: Choose from brass, stainless steel, aluminum, or carbon steel to match your mechanical and environmental requirements.
Easy Installation: Designed for heat set, press-fit, or ultrasonic installation into 3D printed parts.
Customizable: Support OEM/ODM service — logo engraving, surface finish customization, and special size options available.
Our metal threaded inserts for 3D printer assemblies are produced with advanced precision technology to ensure durability and reliability:
CNC Machining: High-accuracy turning and milling to achieve fine thread detail and dimensional stability.
Automatic Lathe Turning: For mass production with consistent quality and tolerance control.
Knurling Process: Creates the outer pattern for secure engagement with thermoplastics.
Heat Treatment: Improves hardness, wear resistance, and tensile strength.
Surface Finishing: Enhances corrosion protection and visual appearance.
We offer several high-quality material options for threaded inserts for 3D printed parts, depending on performance needs:
Brass (Most Common): Excellent thermal conductivity for heat set threaded inserts, ensuring smooth installation and reliable bonding in 3D printed plastics.
Stainless Steel: Superior strength and corrosion resistance; ideal for demanding industrial or marine environments.
Carbon Steel: Provides maximum strength and torque resistance for mechanical assemblies.
Aluminum Alloy: Lightweight, corrosion-resistant option suitable for high-precision prototypes.
Each brass threaded insert for 3D prints or metal threaded insert for 3D printer is carefully selected to provide the perfect balance between strength, weight, and thermal performance.
To meet specific appearance and corrosion-resistance needs, we provide multiple finishing techniques:
Polishing: Smooth and reflective surface finish.
Electroplating: Nickel, zinc, or chrome plating for enhanced corrosion protection.
Anodizing: For aluminum inserts, offering both durability and aesthetic color options.
Passivation: For stainless steel parts to improve oxidation resistance.
Sandblasting: For matte texture and improved bonding surfaces.
Our heat set threaded inserts are produced under strict ISO 9001:2015 and IATF 16949 quality systems.
Tolerance Accuracy: ±0.01 mm
Surface Roughness (Ra): ≤0.8 μm
Inspection Equipment: CMM (Coordinate Measuring Machine), Thread Gauges, Optical Projectors, and Hardness Testers.
Full Process Inspection: From raw material testing to final packaging, every insert undergoes 100% quality verification.
