No, I came into this for mechanical prints 7 years or so ago. I would expect there to be dedicated Blender fora where you can ask.

The slicer (such as Cura) will be fine. Your printer will likely come with some default settings which will be sufficient to get started.

Blender is the sculpting tool you will master. Cura is the oven. Baking is important, but the general art is in the mastery of the pottery tools.

Assuming this is all new, it is not a small thing to learn. Some are faster than others but becoming proficient may take months if it’s a side gig. It is really fun though. Blender will also allow you to make gorgeous renderings if you’d want but I would stay out of that if you really want to print things as it’s another deep and super interesting topic.

Good luck!
