What is the STL file size limit? Both Bambu Studio and Orca freeze when importing a 80mb STL file (1.6m triangles)
Technically there is no limit in the STL file format specification.
But different implementations (reading and writing) will have limits like 2/4 Gig files, or 2/4 billion points or triangles. I have created and used STL files over 1 Gig without a problem with many applications… but some applications fail because they use 32 bit integers for file size or object counts. Oh, but you may have more luck if you use Binary STL instead of ASCII STL (smaller, faster).
That said, a common problem with 3D apps is just inefficient memory usage in applications - so a large file may take more time to process. And any operations they do on the data set may be even slower than reading/writing.

Your computers just gonna chug. Couple of projects I have are 300mb+ and some 1gb+ that are topographical IRL data. It takes time to slice

Fire up Task Manager and see what is happening when Studio appears to hang. Check CPU usage, disk usage, and memory usage. CPU usage should be non-zero, disk usage should be non-zero, and memory usage should steadily increase. If you don’t see that, it’s hung. If you do see that, you need a faster computer.

Easily have 1/2 a gig or more on the build plate with a resin printer (warhammer squads if you wanted to know, 40 MB per trooper) . Slicer should be able to handle that. I suspect either the STL file is bad, or there is a computer problem.
