Some Ideas to Slice Large Files

My rasp pi 3 can not slice file bigger than 140 MB, when I try it freeze about layer 500. I wounder if it is possibles to implement this ideas to help .

1 - Process the plate file in parts ex. salve after each 100 layers. ( if it freeze when You restart it will process ne next 100 layer an so on).
2 - Merge plates, Have 2 or more plates with parts in different location and merge them to print at once. Processing image will take less memory than processing stl.
3 - Be able to slice only some layers ex. 1 to 100 , 101 to 200 , to print separate plates to help with it and maybe a feature to print some plate in sequences.

Thanks

Thank you for the ideas.

Are you using infill? Without infill 140MB should not freeze rpi.
Majority of memory get used by STL file triangle data. Due to way STL works we need to load whole thing into memory.

I'm trying without infill.
Do you have plans to make a nanodlp like a suite? To run in windows more unfriendly?

Ooops I made some typos.
I mean a program or webpage to control your printer to send only processed codes and sliced plates.
