STL is about all you can get out of OpenSCAD. However, FreeCAD has a useful feature that lets you paste OpenSCAD text files and generate solid objects in FreeCAD. At that point all kinds of file formats can be generated (to transfer to other cad systems). OpenSCAD is a "programmer's 3d cad

You'd use a very low fill density, no fill if the pattern can be done that way. Better slicers now have a variable density fill capability along with variable layer height.Another benefit of 3D printing PLA for single use casting patterns is they can be much closer to net shape, which will

3D printing needs STL format. Any 3D modeling or CAD software that can output STL can be made to work as a source for this. One thing though, all the 3D slicer software assumes you're working in millimeters. That's due to the original scanning laser and vat of resin 3D printers only being able
