Filament ROSA3D ROSA-Flex 96A TPU 1.75 mm Black 1 kg

ROSA3D ROSA-Flex 96A TPU 1.75 mm Black 1 kg is a flexible thermoplastic polyurethane filament designed for FDM 3D printing. With a nominal diameter of 1.75 mm and a 1 kg spool, this black TPU filament offers a Shore 96A hardness that balances elasticity and wear resistance. It is formulated for printing flexible functional parts, wearable components, seals and gaskets, and rapid prototyping on desktop 3D printers compatible with 1.75 mm TPU materials.

Advantages

ROSA-Flex 96A provides high abrasion resistance combined with noticeable flexibility, allowing printed parts to bend and recover while keeping surface durability. The filament's consistent diameter and spool winding reduce risk of feeding issues in direct-drive and many Bowden extruders when tuned for TPU. Its black color delivers uniform appearance for functional prototypes and end-use parts without additional finishing.

Suitable for

• Flexible functional parts and small mechanical components
• Wearable items and soft housings
• Seals, gaskets and vibration-damping elements
• Rapid prototyping where elasticity and abrasion resistance are required
• Models printed on desktop FDM printers accepting 1.75 mm TPU filament

Key specifications

• Material: Thermoplastic polyurethane (TPU) with Shore hardness 96A
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg
• Color: Black
• Print compatibility: Designed for FDM/FFF desktop printers that support flexible filaments
• Mechanical properties: High elasticity with good abrasion resistance for wear-prone parts

How to use

Load the filament on a printer configured for flexible materials and ensure a clean, smooth filament path to the extruder. Set nozzle temperatures and print speeds according to your printer and material guidelines for TPU with Shore 96A; typical settings often include moderate nozzle temperature and reduced print speed compared with rigid filaments. Use a direct-drive extruder where possible or tune retraction and feeding parameters for Bowden setups to prevent buckling. Prepare the build surface with appropriate adhesion methods (heated bed, glue stick or PEI sheet) and slice models with adequate wall and infill settings to achieve the desired flexibility and strength.

Usage recommendations

For best results, print at lower speeds and minimize retraction; maintain a straight filament path and consider using a direct-drive extruder. Adjust infill and wall thickness to balance flexibility and structural integrity. Store the spool in a dry, cool environment or sealed container with desiccant to prevent moisture uptake, which can affect print quality.
