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.
Concrete doesn’t dry; it hydrates and cures. It can harden underwater, let alone inside a container.
If anything, the potential problem with concrete is that curing is exothermic, so it might heat up and distort your part. It’d have to be a pretty big print for that to happen, though.
It does both. Once it’s cured, you might want it to dry. Not sure if that’s important here though.
