Hello,
I just built a DLP 3D printer. Its printed part is as shown on the picture.
The quality of the part is not good, but I don't know how to fix it.

Looks "yummy", like jelly beans smiling smiley

Did you try to slow down the print, to allow longer curing periods?

... you have to adjust the curing time to get best results -- could be, adding some more pigments to avoid "over-exposing" and rising the curing time per layer would help ...

Thank you for your nice suggestion. I will try to expend the curing time.

Does "rising the curing time" mean "expending exposure time"?
