3Dputty HDT, our light curing durable high Heat Deflection Temperature putty

Product description

3Dputty HDT is a light curing durable high Heat Deflection Temperature putty curable with UV & visible light in seconds.

Its usage is ideal for filling gaps and holes, repairing and restoring imperfections of damaged or broken 3D prints with similar physical properties. 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 durable high HDT material.

Application framework

Testing & processing disclaimer

High Heat Deflection Temperature HDT 3D resins despite being rigid tend to be fragile and have a short lifetime, degrading thermally at high temperature.
