Formlabs SLS – TPU 90A Powder

$799.00

Formlabs TPU 90A Powder is a tough, flexible elastomeric powder engineered for producing resilient, skin-safe parts with high elongation and superior tear strength using SLS 3D printing technology. TPU 90A Powder balances flexibility and durability, making it ideal for functional prototypes and end-use components that must withstand repeated bending and everyday use — including gaskets, seals, wearables, padding, and soft-touch elements.

Manufactured for consistent performance in Fuse Series SLS systems, TPU 90A Powder delivers excellent mechanical properties with a low refresh rate that reduces cost per part while maintaining flexibility and strength, making it well suited for engineering, medical, and consumer product applications that demand long-lasting resilience and skin contact suitability.

Why Choose TPU 90A Powder?
Produce flexible, resilient elastomeric parts with TPU 90A Powder, engineered for selective laser sintering (SLS) to deliver high tear strength, excellent elongation, and skin-safe performance for functional prototypes and end-use components.

Tough and Flexible
TPU 90A Powder is a durable elastomer with high elongation at break and superior tear strength, making it ideal for parts that must withstand stretching, impact, and repetitive motion without failure.

High Elongation and Tear Strength
Create strong yet flexible parts that combine elasticity with strength, supporting applications where energy absorption, bending, and resilience are critical.

Skin-Safe for Wearable Parts
Formulated for skin safety, TPU 90A Powder is suitable for wearable prototypes and parts that contact skin for short durations, including customized wearables and soft-touch elements.

Efficient SLS Workflow
Compatible with Fuse Series SLS 3D printers and optimized with a low powder refresh rate to reduce waste and cost per part, TPU 90A Powder delivers reliable results for both prototyping and low-volume production.

Applications
Ideal for functional parts that require flexibility, toughness, and repeatable performance.

Consider TPU 90A Powder for:

  • Wearables and flexible components
  • Gaskets, seals, tubing, and masks
  • Soles, splints, orthotics, and prosthetics
  • Padding, dampers, and cushions
  • Soft-touch ergonomic fixtures and grips

Material properties may vary depending on part design, print settings, and post-processing. Users are responsible for validating performance for their specific application.
