Descrizione
3DXSTAT™ ESD-Flex TPU 90A [Thermoplastic Polyurethane] Elastomer is an engineering-grade thermoplastic preferred for its balance of excellent flexibility, ESD safety, ease of printing, chemical resistance, and toughness.
The benefits of Flexible TPU include:
- High elongation, over 300%
- Semi-flexible Shore hardness 90A
- Ease of printing compared to similar flexible materials
- Excellent layer bonding
- Exceptional fatigue resistance
- Very low odor during printing
- Low moisture absorption
- Maintains flexibility even at low temperatures
- Styrene and BPA free
The benefits of 3DXSTAT™ include:
- Constant surface resistivity
- Better impact retention and stretch
- Low particulate contamination
- Minimal contribution to outgassing and ionic contamination
Typical applications of Flex ESD include:
- Semiconductor: HDD components, wafer handling, masks, enclosures and connectors
- Industrial: transportation, measurement and sensing applications
Target conductivity for 3DXSTAT Flex TPU:
Surface resistivity of 10^3 ohm on 3DP sample using the concentric ring test method.
Note: Internal studies have shown that increasing extruder temperatures can achieve higher conductivity levels. Similarly, lower extruder temperatures have resulted in lower conductivity levels. Each printer is configured differently, not to mention the varying part geometry. Therefore, expect some testing time to understand how ESD Flex filament works in your specific printer and application.
Surface conductivity as a function of extruder temperature:
The surface resistance of your printed ESD Flex part varies depending on the printer's extruder temperature. For example, if tests indicate that the part is too insulating, increasing the extruder temperature will result in better conductivity. Therefore, the surface resistance can be "dialed in" by adjusting the extruder temperature up or down depending on the reading you receive from your part.
Recommended print settings:
- Extruder: 220-240°C
- Bed temperature: 40-60°C
- Bed Prep: Hairspray over a layer of Magigoo Bed Prep gives us the best results.
- Heated room: not required
- Supports: The water-soluble USM AquaTek™ X1 Universal Support Material is ideal for complex parts
- Drying instructions: 65°C for 4 hours.
