Delrin, also known as Polyoxymethylene (POM), is a thermoplastic commonly used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. Here are the key benefits of using Delrin in 3D printing:
Key Benefits
- High mechanical strength – Delrin is known for its strength and rigidity, which is essential for functional and load-bearing components.
- High resilience – Delrin parts can endure repeated stresses without significant deformation.
- Low friction & wear resistance – This material is self-lubricating, which makes it ideal for applications involving moving parts.
- Good moisture resistance – Delrin does not absorb much moisture, making it suitable for use in wet environments.
- Excellent dimensional stability – With minimal expansion and contraction, Delrin is ideal for creating precise and consistent parts.
- Chemical resistance – It resists many solvents and chemicals, making it suitable for challenging industrial applications.
- Gears and bearings
- Electrical engineering components (insulators, switches)
- Automotive parts (door handles, locks)
- Sports equipment
