3Dresyn IJ WSS1-HF Water Swellable Support Hard & Flexible grade

3Dresyn IJ WSS1 HF is a water-swellable support photopolymer formulation designed for high-performance inkjet 3D printing workflows requiring controlled support generation and easy post-processing removal. The material is engineered to deliver a balance between hardness and flexibility, enabling reliable support during printing while allowing efficient removal through water swelling mechanisms.

This formulation provides structural integrity during printing together with controlled swelling behavior in aqueous environments, supporting the fabrication of complex geometries with internal channels, overhangs and intricate features.

Designed for use in commercial and professional inkjet 3D printing systems as a dedicated support material for complex parts requiring water-assisted removal processes.
