A method of forming a three-dimensional part is disclosed, including ejecting one or more drops of a print material at a first frequency to form a portion of a three-dimensional part. The method also includes ejecting one or more drops of the print material at a first line spacing, creating an unsupported overhang onto the three-dimensional printed part where the unsupported overhang is oriented at an angle of from 0 degrees to about 45 degrees relative to a print bed, and ejecting one or more drops of the print material at a second line spacing when creating at least a portion of the unsupported overhang. The method of forming a three-dimensional part further includes where drops are ejected at a first drop spacing when ejected at the first line spacing or at the second line spacing, and no portion of the unsupported overhang contacts the print bed.
