ROSA3D TPU 96A Filament, 1.75mm, 0.5kg, Black

ROSA3D TPU 96A is a high-quality, flexible thermoplastic polyurethane filament designed for FDM/FFF 3D printers. This 1.75mm diameter material is engineered for technical applications requiring high mechanical strength, elasticity, and resistance to environmental factors. It maintains its original shape even after repeated stretching or compression, making it a reliable choice for functional parts that must endure physical stress.

Advantages

The primary benefit of ROSA3D TPU 96A is its exceptional durability and resistance to mechanical damage, including abrasion. It features excellent interlayer adhesion, ensuring that printed components are robust and cohesive. Furthermore, the material exhibits significant chemical resistance, remaining stable when exposed to oils, greases, and various solvents. Its flexibility allows for the creation of parts that can be deformed and returned to their original state, while the composition includes ingredients approved for food contact, providing versatility for specialized projects.

Suitable for

• Gaskets, bumpers, and anti-vibration dampers
• Smartphone cases and protective device housings
• Components for drones and RC vehicles
• Flexible prototypes requiring high tensile strength

When it may not be suitable

This filament may not be ideal for applications requiring extreme rigidity or high-temperature resistance beyond the thermal limits of standard TPU. Additionally, because it is a flexible material, it may be challenging to print on printers with long or poorly constrained Bowden-style extruders, which can lead to filament buckling.

Key specifications

• Diameter: 1.75 mm
• Net weight: 0.5 kg
• Density: 1.22 g/cm³
• Elongation at break: 350%
• Extrusion temperature: 210-250 °C
• Bed temperature: 50-70 °C
• Odor: Odorless

How to use

To achieve optimal results, ensure your printer is calibrated for flexible materials. Load the filament into your extruder, ensuring the path is as direct as possible to prevent tangling or buckling. Set your extrusion temperature between 210°C and 250°C and the bed temperature between 50°C and 70°C. While a heated bed is not strictly required, it can improve adhesion. If you encounter issues with the first layer, apply a suitable adhesive agent to the print surface, such as glass or PEI.

What to consider before purchase

• Ensure your 3D printer extruder is compatible with flexible filaments.
• Verify that the 0.5kg spool size fits your printer's spool holder.
• Check if your project requires specific chemical resistance properties.
• Note that final product food safety certification is the responsibility of the end-user.

Usage recommendations

For the best print quality, start with a printing speed of 15-50 mm/s and adjust cooling fans based on the model's geometry. Always store the filament in a dry place to prevent moisture absorption, which can affect print quality.
