Esun Water-Washable Resin

 

A while ago I bought a bottle of white Esun water-washable 3d printing resin. It isn't the most expensive resin available by any means, but it's not cheap. And it's absolutely terrible.

This 1:144 model, in the process of being painted (I don't know yet if I'll bother finishing it) is pretty typical of the results I get from this particular resin. Delamination cracks appear at regular intervals. Deformations abound, and the fit of separate components cannot be guaranteed — in fact, they can almost be guaranteed not to fit. And once cured, it is pathetically brittle and fragile.

I don't know enough about 3d printing resins to be able to usefully diagnose the likely problem(s), but I have had much better results in the past with other of Esun's water-washable stuff, especially the translucent resins, so I suspect it may be an issue with overloading of the opaque pigment used to colour it.

I am so mean that I've persisted with it so far instead of dumping it, but today frustration has finally outweighed my stinginess, and out it goes to cure in the sun and be discarded.
