Product Description

ERYONE TPU 90A Transparent 1 kg is a high-quality flexible filament made of thermoplastic polyurethane (TPU), designed for 3D printing parts that must be flexible, impact-resistant, and durable. The transparent design is ideal for design and functional parts where translucency or visual inspection of internal structures is desired.

The filament utilizes Shore 90A hardness, which represents a great compromise between flexibility and stiffness: the model can be bent and compressed, but at the same time maintains its shape and sufficient mechanical strength. The material is suitable for most common FDM 3D printers.

Key Features

• Material: TPU (thermoplastic polyurethane)
• Hardness: Shore 90A – balance between flexibility and strength
• Color: Transparent
• Filament diameter: 1,75 mm ± 0,03 mm
• Spool weight: 1 kg of filament
• Flexible and tough – withstands repeated bending and impacts
• Resistance to water, heat, and oils – suitable for more demanding environments
• Good bed adhesion and reliable material flow
• Compatible with most FDM 3D printers (especially suitable for direct extruders, but can be printed on a well-tuned Bowden system)

Recommended Use

ERYONE TPU 90A Transparent is suitable for a wide range of applications:

• Protective cases and covers (mobile phones, electronics)
• Damping and flexible elements (bumpers, stops, silentblocks)
• Seals, bellows, and functional rubber parts
• Flexible connectors, joints, and hinges
• Design and transparent elements, light diffusers, LED covers
• Toys, prototypes, and models requiring flexibility

Thanks to its transparent design, the filament is also ideal for visual inspection parts where there is a need to see internal channels, infill, or liquid flow.

Printing Recommendations

To achieve the best results, the manufacturer recommends the following settings:

• Nozzle temperature: 200–220 °C
• Bed temperature: 0–60 °C (recommended 40–60 °C depending on surface type)
• Print speed: 15–40 mm/s
• Retraction: approx. 4–5 mm (fine-tuning may be necessary for Bowden extruders)
• Cooling: low to medium depending on part geometry

When printing flexible materials, it is recommended to:

• reduce filament feed speed and acceleration,
• minimize overly aggressive retractions,
• ensure a clean and properly leveled print bed.

Advantages of ERYONE TPU 90A Filament
