Only thing I would worry about is the material shrinking as it cures and how much heat it may generate as it cures. It looks like a fairly small mass, but you won't know unless you try!

Thanks Nick!
I ordered a Quart sampler and will check it out.

Take a look at Smooth-On's Encapso K.

It can be poured thick and the bubbles generally work themselves out just fine with no pressure chamber.

Hello All,

I'm trying to fill an SLA printed bottle ( bottle on right in pic) with a material that when cured (hard), will resemble clear liquid.
I tried an epoxy but the viscosity didn't let the tiny bubbles float to the top and escape.
I've let excess 2-part urethane cure in a glass jar and it had large cracks when cured.
Should I go for a casting urethane? Will the viscosity be thin enough for bubbles to escape? I have no pressure chamber.
The bottle has been urethaned on the inside and outside surface.
I could print the liquid area as a solid in the future but wanted to explore this option to save printing costs, as my client may order quantities.
Any recommendations are greatly appreciated.
Thank you!!
