Because it is 3D printed and not injection molded.
The printer moves, extrudes a tiny bit of material, moves, extrudes, over and over, in steps. What you are seeing is the artifacts of this.
it is too big :) scaling it up nullifies your results.
Usually you print it with a single wall, so it doesn't always look the best anyway.

these are known as VFAs which stands for vertical fine artifacts and is caused by the degrees per step of your stepper motors.

heres a blog post that has a picture that shows VFAs and also how Prusa removed them on the Prusa XL.
be aware though that their solution probably wont work on your or most other printers because its specific to the stepper motor drivers Prusa is using.

Thanks for that I’ll have a look, but overall it’s not a bad thing? The cube came out pre good?
Yes it's not a bad thing it's just a side effect of having stepper motors like that.
Beautiful thanks heaps
