TPU filament for soft, flexible, wear-resistant 3D prints

Unveil Form ShoeFlex 9075A is a 1.75mm TPU filament supplied on a 0.75kg spool for printing soft, flexible parts with rubber-like behaviour. The material is designed for printed components that need cushioning, stretch, repeated bending, surface grip, and better impact absorption than rigid filaments.

ShoeFlex 9075A is made for shoe printing and other applications where a soft printed result matters more than rigid structural performance. The filament is rated at 90A hardness and prints into 75A shoes, giving finished parts a soft flexible feel suited to comfort-focused and compressible designs.

Key features of Unveil Form ShoeFlex 9075A

• Soft printed flexibility: the printed 75A result suits parts that compress, bend, and recover during regular use.
• TPU durability: TPU is well suited to abrasion resistance, repeated flexing, impact handling, and frequent handling.
• 1.75mm filament format: compatible with a broad range of desktop FDM and FFF 3D printers that use 1.75mm material.
• 0.75kg spool size: practical for testing, prototyping, shoe model development, and lower-volume flexible part production.
• Diameter control within ±0.03mm: supports consistent material feed for reliable extrusion.
• Elegant grey / light grey colour: useful for clean-looking prototypes, neutral assemblies, and functional parts that may be finished or colour-matched later.
• Beginner-friendly printing profile: the product information identifies the material as easy to print for beginners, while noting that the filament softens as it prints.

Benefits for flexible functional printing

Soft TPU helps printed parts absorb shock and keep functioning under repeated movement. Compared with rigid materials, ShoeFlex 9075A is better suited to components that need to deform in use without cracking or taking permanent damage.

The TPU surface also supports good grip and tactile comfort, making the filament useful for contact points, covers, and protective features. When the material is dried and printed with TPU-appropriate settings, ShoeFlex 9075A can produce durable parts for regular handling and mechanical flex.

Use cases for shoe printing, comfort parts, and flexible prototypes

• Footwear and comfort prototypes: shoe models, soft pads, cushioning concepts, and flexible wearables.
• Protective parts: bumpers, edge guards, sleeves, and impact-damping covers.
• Grip components: handles, tool grips, controller accessories, and anti-slip contact surfaces.
• Flexible mechanisms: straps, seals, tabs, and compressible joints where rigid plastics are too stiff.
• Product development: testing soft-touch geometry, fit, flex behaviour, and wearable comfort before moving to production methods.

Who this TPU filament suits

Unveil Form ShoeFlex 9075A suits makers, engineers, designers, educators, and prototyping teams that need very soft FDM-printable material. It is especially relevant for projects that call for compressible, wearable, or impact-damping parts rather than hard housings or high-stiffness fixtures.

The listed M.V.S. values are 2.8-3.6mm³/s with a 0.4mm nozzle and 3.0-5mm³/s with a 0.6mm nozzle, helping define an appropriate output range for this soft TPU in practical printing setups.
