Choosing a 3D printer for a teapot?

Question

3D

A small amount of money accumulated here and it was decided to spend it on the simplest 3D printer, simply because some things, so to speak, needed in the household, although more expensive, are more convenient to print than to sculpt with pens, in connection with which several questions arose:
1. What is the entry threshold, given that I used to model cans of cola and basketballs in Blender?
2. Will any 3D editor work with a printer?
3. What to choose anyway? Should I look towards the 3D printer "Start"?
Well, in general, I’ll print ready-made models, then try to slightly change them and take such steps to my models?

Answer 1

1) minimal ... the main thing is to understand the subtleties of export in order to avoid jambs
2) the blender is more than max for CAD designed, even one person used it for the "laser wood burner" one man used (modeled a machine -> cut -> assembled) still there you can turn on the display of the length of the edges,
even though the blender exports files for printing, but it’s better to run them through special “slicers” (programs that prepare for printing)
3) I advise cheap PRUSA I3, although I haven’t used it myself, but the reviews are good, it’s not expensive and there are a lot of materials on modifying it and fixing problems.
PS, as I understand it, these PRUSA I3 are something like a model that is made by different companies and they must have standardized drivers ...
about changing models from a "ready to print" .STL file, I'm not sure, because it seems to me different from the usual .OBJ and .FBX formats ...
Ps I don't know anything else, amateur ... I'm thinking about buying it myself
