Filling 3D prints with filler material (discuss.tchncs.de)

Do you have any experience doing so?

I have a project coming up where I would like to print a large object and fill it with sand and resin.

Sand, as we all know is coarse, rough and irritating and it gets everywhere. So it's good filler material.

Afterwards I want to solidify it by adding resin, hoping that it gets everywhere as well.

What other materials are usable? Perhaps concrete but it can't really dry inside a printed object right?

The infill should be Gyroid with 10% with at least 3 perimeters IMO. Would something like tree infill work as well? Or removable infill? I'm not sure how to get a slicer to do that though.

I intend to build parts for a CNC machine so I value weight and rigidity in this project.

I sometimes fill the bottoms of smallish boats with hot glue to get them to float well.

Pros: Glue spreads easily, fits crevices, and is pretty cheap and easy to use.

Cons: Bit messy, not particularly heavy (though does make the prints feel more solid), bit of a pain to sort out how much glue to use and at what intervals while printing.

Can't say whether glue would be a good fit for CNC machine parts though.
