Introduction to ULTEM 9085
ULTEM 9085, a high-performance polyetherimide (PEI) polymer, is revolutionizing aerospace, medical, and automotive industries. Known for its flame, smoke, and toxicity (FST) ratings and UL94 V-0 certification, this material ensures safety in critical applications like aircraft interiors and race car components.
Why Use ULTEM 9085?
With properties like self-extinguishing flames, low off-gassing, and high resistance to hydrocarbons, ULTEM 9085 is ideal for harsh environments. It replaces metal components in applications where weight reduction and high durability are paramount.
The 3D Printing Workflow
Printing with ULTEM 9085 involves a detailed workflow:
- Preheating: Preheat the 3D printer to stabilize the high-temperature chamber and build plate.
- Material Preparation: Use vacuum-dried filament to ensure the polymer is free of moisture, preventing print defects.
- Slicing: Optimize part orientation and apply advanced techniques like brims and lily pads to combat warping.
- Printing: Leverage high-temperature machines like the 22 IDEX V3 to achieve exceptional layer adhesion and precision.
Pro Tips for Successful Prints
Optimize Your Slicer Settings
For ULTEM 9085, configure slicer settings for superior results:
- Layer height: 0.12 mm for high-quality finishes.
- Infill: Use a low-warp pattern like Hilbert Curve at 5% for lightweight parts.
- First layer: Increase thickness for better bed adhesion.
Handle Warping with Lily Pads
Apply sacrificial “lily pads” at high-warp areas to anchor the part to the build plate and minimize deformation.
Use Nanopolymer Adhesives
Enhance bed adhesion with specialized adhesives like Vision Miner’s Nanopolymer Adhesive, ensuring parts stay flat during high-temperature printing.
What Makes ULTEM 9085 Unique?
Its UL94 V-0 rating means ULTEM 9085 self-extinguishes flames, emits minimal smoke, and maintains structural integrity under extreme conditions. A demonstration with a propane blowtorch confirmed its superior safety properties.
Conclusion
ULTEM 9085 is a game-changer in additive manufacturing, offering unparalleled safety and performance. If you’re exploring high-temperature materials, machines like the 22 IDEX V3 and the right preparation techniques can ensure success.
