摘要：
The invention relates to a deformable absorbent substrate (14) for a packaging and/or application assembly for a cosmetic product (10), having lattices (24) defined by edges (26). The edges (26) can be produced in particular by means of additive manufacturing, in particular by selective laser sintering, selective laser fusion, stereolithography, or taut wire deposition.
