For quick STL modification and part separation specifically for 3D printing, here's my workflow:
1. Blender for most of the work - it's free and handles STL files natively. The mesh separation tools are excellent once you learn them (use the knife tool + separate by selection). For creating printable bodies, the Solidify modifier is your friend.
2. If you're struggling with complex separations in Blender, try Meshmixer (free) which is purpose-built for this kind of work. The "Separate Shells" and "Plane Cut" features are extremely useful.
For what you're describing, investing time in fancy paid software isn't worth it. The tools in Blender + Meshmixer will handle 95% of what you need for prepping models for resin printing.
Always run your models through PrusaSlicer or Chitubox before printing to check for issues, even if you prepared them elsewhere.
Dear Harold, thank you very much for your support;
I have used Blender for few time in the past and I'd like to improve my skills about this topic; could you help me, please? Could I contact you directly?
I am starting this new hobby and my aim is to create the car model of my first sport car.
Thank you
