Flexible Resin: Soft Prototypes and Recovery

Flexible printing resin is a photopolymer formulation designed for a specified range of compliant behaviour. Material reference.

Soft Prototypes and Recovery

For a grip or soft prototype, compare hardness with geometry, recovery and repeated deformation. A similar Shore number does not make the part equivalent to a moulded silicone or TPU component. Specify whether the prototype is demonstrating touch, fit or actual sealing performance.

Manufacturing and acceptance checks

Request the exact resin, hardness test method and cure route. Define wall thickness, compression or bending travel and recovery time. Approve a fully processed sample, checking surface condition and repeated-use behaviour with the intended contact and cleaning conditions represented.
