1. An additive manufacturing device comprising:
a vat, wherein the vat is suitable in size and material to contain a liquid light-hardenable resin;
a build carrier comprising a build platform, the build platform comprising a build surface for building up an object thereon, wherein a surface section of the build surface comprises a ceramic material having a non-porous material structure, wherein the build surface comprises a plurality of spaced planar surface sections that extend in a common plane, and wherein a gap is formed between adjacent surface sections, the gap having a width in a dimension of the common plane and a depth in a dimension perpendicular to the common plane; and
a light source for emitting light toward the build surface, wherein build carrier and the light source are movable relative to each other;
wherein the build carrier is movable through the vat in a direction of build dimension.
