artisan: a skilled craftsperson or manual worker
A number of artisans can be seen at work behind their market stalls.

artist:a person skilled in a fine art (such as painting, silversmithing or sculpting)

artiste: a professional performer or enteratiner, especially a dancer or singer; someone with artisitic pretensions
Dame Nelly Melba was an artiste renowned for her farewells.

So an artisan is skilled a manual skill outside of the fine arts, which could include a mechanic, a carpenter, a cook and a draftsperson. Some artisans may be artistic even if they don’t work with a fine art.
