Description

SUNLU TPU-95A filament delivers outstanding flexibility and mechanical resilience, making it suitable for a wide range of functional applications requiring elasticity and impact absorption. This thermoplastic polyurethane material is engineered to achieve a Shore hardness of 95A, offering a balance of softness and structural integrity. Its robust formulation ensures consistent extrusion and layer adhesion, providing excellent print quality for detailed flexible parts.

Printing with SUNLU TPU-95A requires careful consideration of speed and temperature settings to prevent stringing and ensure optimal bed adhesion. Users can fine-tune slicing parameters, such as infill density and wall thickness, to achieve desired levels of part softness or rigidity. While accommodating slower cooling for stable larger prints, it is recommended to avoid excessively hollow or complex overhanging structures to maintain dimensional accuracy and print success. The material is designed to prevent common issues like nozzle cuts and wobbling, resulting in durable, precise, and elastic final prints.

Key Features

  • Shore 95A hardness offers a balanced blend of flexibility and structural support.
  • Excellent layer adhesion minimizes delamination and enhances part durability.
  • Optimized for consistent extrusion, reducing common printing issues like nozzle clogging.
  • Allows precise control over part flexibility through infill and wall thickness adjustments.
  • Exhibits strong resistance to abrasion, impact, and wear.
  • Low moisture absorption compared to some other flexible materials, but drying is recommended.
  • Produces smooth surface finishes on appropriately tuned printers.
  • Compatible with direct drive and most Bowden style FDM 3D printers.

Applications

  • Flexible gaskets and seals for enclosures.
  • Protective cases for electronics and devices.
  • Wearable components and ergonomic grips.
  • Dampening pads and vibration isolators.
  • Automotive parts requiring flexibility and impact resistance.
  • Prototyping functional parts with elasticity.

Frequently Asked Questions

How should I dry TPU filament before printing?

TPU is hygroscopic; drying is crucial. Place your filament in a dedicated filament dryer at 55-65°C for 4-6 hours prior to printing. This removes absorbed moisture, preventing bubbles, stringing, and improving print quality significantly. Proper drying ensures optimal mechanical properties.

What are the optimal print settings for Sunlu TPU-95A?

Optimal print temperature is typically 200-220°C with a bed temperature of 50-60°C. Printing speed should be slower, around 20-40 mm/s. Use a retraction distance of 1-3mm with slow retraction speed to minimize stringing. A direct drive extruder is recommended.

How can I improve bed adhesion when printing with TPU?

For reliable bed adhesion, use a textured PEI sheet, Kapton tape, or a glue stick applied to a glass bed. Ensure your bed is level and clean. A brim or raft can also significantly enhance first-layer adhesion, especially for models with a small footprint.

Can I print complex geometries or supports with TPU-95A?

While TPU is flexible, printing highly complex geometries or fine supports can be challenging due to its elastic nature. Keep retraction settings minimal to avoid clogs. For supports, design them to be easily removable and consider slower speeds and larger contact areas for better results.
