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. The flexible material is suited to prints that need bend, resilience, abrasion resistance, and better impact handling than rigid plastics.

The 90A/75D hardness profile makes this TPU useful for parts that must flex in use without becoming overly soft. ShoeFlex is a practical choice for functional prints where grip, cushioning, or repeated deformation 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/75D hardness: Balances flexibility with structure for parts that need both compliance and shape retention.
• 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.

Where flexible 90A TPU works well

This TPU filament is well suited to 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.
