ROSA-PLAST Flex 96A 3D printing filament 1.75 mm 0.5 kg — Black

ROSA-PLAST Flex 96A is a flexible 3D printing filament in black with a 1.75 mm diameter on a 0.5 kg spool, intended for FDM/FFF printers that accept 1.75 mm filament. The material behaves like a TPU with a Shore hardness of approximately 96A, offering limited but usable elasticity for parts that require bending resistance and some shock absorption. This filament is formulated for consistent extrusion and can be used to produce elastic components, gaskets, wearable details, and functional prototypes where flexibility and surface finish are important.

Advantages

ROSA-PLAST Flex 96A provides a balance between rigidity and elasticity, enabling prints that retain shape while allowing limited deformation. The 1.75 mm diameter ensures compatibility with a wide range of desktop FDM/FFF printers and extruders tuned for flexible materials. Its black colour offers good coverage and uniform appearance for visible parts. The 0.5 kg spool size is suitable for small to medium projects and testing of flexible part designs.

Suitable for

• Elastic prototypes and functional parts requiring bend resistance
• Gaskets, seals and vibration-damping components
• Wearable prototypes and soft-touch details
• Small series parts and design validation of flexible elements

Key specifications

• Filament diameter: 1.75 mm
• Spool weight: 0.5 kg
• Material type: flexible TPU-like thermoplastic (Shore ~96A)
• Colour: Black
• Compatibility: FDM/FFF printers accepting 1.75 mm filament

How to use

Load the 1.75 mm filament into a printer configured for flexible materials and follow printer-specific guidance for filament feeding and retraction settings. Begin with moderate print speeds and adjust layer height and flow to achieve consistent extrusion and good layer adhesion. Monitor first-layer adhesion and adjust bed temperature or adhesion aid as needed. Allow printed parts to cool before removing from the build plate to minimise deformation.

Usage recommendations

For reliable prints, use a direct-drive or well-tuned filament path for flexible materials, reduce print speed compared with rigid filaments, disable or minimise retraction where appropriate, and calibrate extrusion multiplier. Recommended starting settings typically include a lower print speed, a nozzle temperature suitable for TPU-like materials, and a heated bed or adhesion surface for improved first-layer bonding.
