Nylon 12: The Versatile Workhorse
Nylon 12 is the most popular MJF material due to its excellent balance of mechanical properties. It's a robust thermoplastic that produces high-density parts with strong, complex structures.
- High strength and stiffness
- Good chemical resistance
- Ideal for complex assemblies, housings, and enclosures
- Biocompatible (USP Class I-VI, FDA Intact Skin Surface Devices)
- Can be dyed black and vapor smoothed
Nylon 11: Durable and Ductile
Nylon 11 is a thermoplastic material known for its optimal mechanical properties and ductility. It is derived from renewable castor oil, offering a reduced environmental impact.
- Strong and ductile
- High elongation at break
- Good impact resistance
- Ideal for prostheses, insoles, sports goods, snap fits, and living hinges
- Can be dyed black and vapor smoothed
Nylon 12 Glass-Filled: Stiff and Stable
This material is a 40% glass bead-filled thermoplastic that provides both optimal mechanical properties and high reusability. It is designed for applications requiring high stiffness and dimensional stability.
- High stiffness and dimensional stability
- Good repeatability
- Ideal for enclosures, housings, fixtures, and tooling
- Engineered for detail and dimensional accuracy
- Can be dyed black and vapor smoothed
Polypropylene: Chemical Resistant and Lightweight
Polypropylene is a thermoplastic polymer known for its chemical resistance, low moisture absorption, and lightweight nature.
- High chemical resistance
- Suitable for water-submersed applications
- Lightweight (0.89 g/cm3 density)
- Good balance of stiffness and toughness
TPU 88A: Tough and Flexible
TPU 88A is a thermoplastic polyurethane that offers a balanced property profile with good flexibility and shock absorption. It is engineered for tough, end-use rubber components.
- Good flexibility and shock absorption
- Toughness for end-use rubber components
- Good UV and hydrolysis resistance
- Ideal for sports and leisure, footwear, transportation industry, and jigs and fixtures
- Can be dyed black and vapor smoothed (pictured)
