3Dputty HDT-WS, our light curing Water Soluble sacrificial high Heat Deflection Temperature putty

Product description

3Dputty HDT-WS is a light curing water soluble sacrificial high Heat Deflection Temperature putty curable with UV & visible light in seconds.

Its usage is ideal as water soluble 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 soluble sacrificial high HDT filler for easy demolding.
