Issues when printing

[RobSly 0]

Hi, I Just built my first 3d printer. I Made a design in tinkerkad and I imported the file to ultimaker cura and started printing on my ender 3 v2. 

 

It prints nice, but it prints a big thin plate below my design.. What is this? How can I prevent this?

That's called a brim.  (like a hat brim) It's very useful - especially for novices to help keep your part sticking to the print bed.  You don't need it for smaller parts but will likely need it for parts that are over 150mm in at least on direction (x or y).

 

Bed adhesion is a complicated issue.

 

Anyway - you can get rid of it at your own peril by changing the "build plate adhesion type" to "skirt" instead which is similar but won't touch the part.  The skirt is to get the flow moving in an equilibrium state so I recommend doing the skirt as a minimum.
