3Dputty SF-WS, our light curing Water Swellable sacrificial Soft & Flexible putty

Product description

3Dputty SF-WS is a light curing water swellable sacrificial soft & flexible putty curable with UV & visible light in seconds.

Its usage is ideal as water swellable sacrificial demolding filler for filling the gap between water soluble sacrificial 3D printed molds and injector flasks. Before exposure to UV / visible light it can be modelled by hand or with a spatula, and after shaping it can be hardened in seconds to become a water swellable sacrificial soft and flexible filler for easy demolding.
