Description

Active Foaming Technology: Temperature-controlled expansion allows you to adjust density and Shore hardness dynamically from 65A to 86A.

Ultra-Lightweight & Buoyant: Reduced material weight creates soft, low-density parts that can float in water.

Tactile Fabric Texture: Produces a unique, non-plastic surface feel resembling woven textiles for premium soft-goods.

Functional Zone Printing: Enables tuned stiffness, cushioning, and density variations within a single continuous print.
