1. A spiral sheet product manufactured via an additive manufacturing process performed by an additive manufacturing apparatus, the spiral sheet product comprising:
a spiral body revolving around a longitudinal axis;
at least one supporting structure extending through a center region of the spiral body and spaced apart from the spiral body;
the spiral body comprising spiral sections repeating along the longitudinal axis;
each spiral section comprising unit cells repeating along a spiral length of the spiral section; and
each unit cell comprising a geometric pattern, such that the geometric pattern is repetitive along the unit cells,
wherein the spiral sheet product is functionalized by the repetitive geometric pattern and is arrangeable into a flat sheet product that is larger than a build chamber of the additive manufacturing apparatus; and
wherein the at least one supporting structure is arranged to prevent toppling of the spiral sheet product during post-treatment of the spiral sheet product.
