perhaps you did not read the post—the author attempted layer-by-layer first but discovered it was impossible to get a smooth final result.

This is apparently a well known issue among people who create resin-cast structures.

I think it may still work if you don't wait until the last layer has completely cured. The viscosity just has to be high enough to be able to suspend the artifacts.

This sums it up:

"To achieve the effect I want, I need around 20 layers for a regular pocket watch movement. If I were to cast each layer in a transparent container, adding components and epoxy as the previous layer was half-cured, I would be doing nothing else for a solid week."
