Which filament types are used in industrial 3D printing?
Industrial 3D printing filaments are defined by specific material properties, including mechanical strength, thermal resistance, and chemical stability. The choice of the right filament ultimately determines component performance and production reliability.
What are the properties of PEEK and PEI filaments for industrial applications?
PEEK and PEI belong to the high-temperature polymers that provide stability and strength even under extreme conditions. High-performance filaments like PEEK (Polyetheretherketone) and PEI (Polyetherimide) are characterized by the following features:
| Material | Heat resistance | Chemical resistance | mechanical stiffness | Flame retardancy |
|---|---|---|---|---|
| PEEK | up to 260 °C | very high resistance to solvents and oils | 3.6 GPa | UL94 V-0 |
| PEI (ULTEM™) | up to 200 °C | high resistance to acids and bases | 3.1 GPa | self-extinguishing |
This combination of temperature resistance and chemical stability enables companies to manufacture components for aerospace, medical technology, and automotive industries, where continuous stress and sterilization cycles are routine. The mechanical stiffness of the polymers and their flame retardancy ensure the highest reliability.
ASTM International, Standard Specification for Polyetheretherketone (PEEK) Materials (2023)
This specification provides detailed information on the properties and standards for PEEK materials, which supports the article's claims about its high-temperature resistance and chemical stability.
What advantages do TPU filaments offer for flexible industrial components?
Thermoplastic polyurethanes (TPU) enable the additive manufacturing of flexible components with excellent abrasion and impact resistance.
- Flexibility and elasticity – TPU filaments allow recovery forces of up to 900% without material fatigue.
- Abrasion resistance – With values over 1000 cycles in the Taber test, seals and dampers are durable.
- Damping capacity – Elastic springs and buffers protect sensitive machine parts.
ISO 4649:2010, Rubber, vulcanized or thermoplastic — Determination of abrasion resistance using a rotating drum device (2010)
This standard provides a method for determining the abrasion resistance of rubber and thermoplastic materials, which supports the article's claims about the abrasion resistance of TPU filaments.
TPU components are found in shaft seals, vibration dampers, and shock-absorbing mounts because this material withstands dynamic load changes permanently and retains shape fidelity.
Why is PA (Nylon) filament suitable for robust industrial applications?
Nylon (PA) impresses with high tensile strength, impact resistance, and versatile processing options.
| Material | Tensile strength | Impact strength | Moisture Absorption | Application examples |
|---|---|---|---|---|
| PA6 | 55 MPa | high | 2–3 % | Gear wheels, bearing bushings |
| PA12 | 50 MPa | very high | 1 % | Housings, pipe brackets |
The balance between strength and toughness makes PA ideal for functional prototypes and small series in mechanical engineering, electrical engineering, and consumer goods manufacturing. Thanks to lower moisture absorption in PA12, dimensional accuracy and shape stability are maintained even in humid environments.
What special filaments like carbon fiber or ESD filaments are available for specific requirements?
Composite materials and conductive filaments open additional application focuses:
- Carbon fiber-reinforced filaments: increase bending and compressive strength by up to 60–80% at 15% fiber content.
