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.

Clean sand does work. But what you probably want is granite resin for this project. It's very popular with machine tool hobbyists and even expensive manufacturers like Hardinge.

Here is an explanation of how to use the stuff

Careful of sand. If you use it, don't run the fan until you cap off the void. Otherwise you're going to blow sand all over
