Yellow TPU filament for flexible, durable 3D printed parts

Unveil Form ShoeFlex 9075A is a yellow 1.75mm TPU filament supplied on a 0.75kg spool for flexible, durable functional prints. The material is made for printing shoe models and other parts that need bend, resilience, abrasion resistance, and better impact handling than rigid plastics.

The 90A filament prints into 75A shoes and other soft-result parts, giving a useful balance between flexibility and structure. ShoeFlex 9075A suits applications where grip, cushioning, repeated deformation, or a softer contact surface matters.

Key features of ShoeFlex 9075A TPU filament

• Flexible TPU material: Produces elastic parts that can bend and recover under regular use.
• 1.75mm filament format: Fits a wide range of desktop FDM/FFF 3D printers built for 1.75mm filament.
• 90A filament, 75A printed result: Balances compliance with shape retention for prints that must flex in use without becoming overly soft.
• ±0.03mm diameter control: Filament diameter is controlled within ±0.03mm for consistent material feed.
• Yellow colour: Creates highly visible parts, prototypes, markers, and components where colour distinction is useful.
• 0.75kg spool: Suitable for prototyping, short production runs, replacement parts, and application testing.
• Beginner-friendly TPU behaviour: The product information identifies the filament as easy to print for beginners and notes that it softens as it prints.

Where flexible 90A TPU works well

This TPU filament is well suited to shoe printing, footwear-related prototyping, soft-touch accessories, anti-slip contact surfaces, gaskets, sleeves, and protective components. The material class is commonly used when a printed part needs to absorb minor impacts, resist wear, or conform slightly to surrounding geometry.

For makers and product developers, ShoeFlex 9075A is a strong fit for jigs with non-marring contact points, cable guides, bumpers, vibration-damping elements, and custom enclosures that benefit from a softer interface. The yellow colour also helps with part identification, visibility, and sorting in workshop or educational environments.

Practical printing behaviour for TPU projects

TPU generally performs best with a controlled filament path, moderate temperatures, and slower print speeds than PLA or PETG. Dry handling and good first-layer setup help produce cleaner surfaces, steadier extrusion, and more consistent flexible parts.

The listed M.V.S values are 2.8-3.6mm³/s for a 0.4mm nozzle and 3.0-5mm³/s for a 0.6mm nozzle. These ranges are useful when planning flow expectations for flexible filament projects.
