Hello Everyone!!

I am new to the 3D printing world but not to 3D. I have seen a lot of great 3d printer out there but there is always a question in my mind, what is the post process once you have your piece printed?. I ask about this because i have notice that with the regular 3D printers (i mean the affordable ones) the quality of the prints is not sharp. What do you do once the printing is done.
