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 thought of that a well. The resin will likely not get everywhere. The idea was saving costs as resin is kinda expensive.
Sand by itself doesn’t add much to rigidity I think, it only adds weight. With only 3 walls and sand you’d probably be lacking in rigidity in the areas without resin.
