Alternative for Blender or is there a way?

[DudeUser 0]

Hey,

i am using Blender since 1 year for photorealistic interior render and Archviz. Now i want to use it for

3D-print but i have a lot problems when it comes to precise and complex shapes. I know Blender

is not a CAD programm but is there a way or must i learn a new programm like FreeCAD?

I would like to stay with blender, because it is very comfortable to use for me.

You can still use Blender to create 3D models for 3D printing. Just make to run it through a repair service to ensure that your design doesn't have any 3D printing errors. There is also a plugin you can download for Blender that repairs your model for printing: https://makeprintable.com/page/15/Plugins-Overview
