The invention relates to an additive production method involving the production of a layer of geometrically compact particles, having the following steps: a) providing a particle layer depositing arrangement, comprising a first and a second semi-chamber, wherein a partition separates the first semi-chamber from the second semi-chamber, and the partition is permeable for a dispersion medium and impermeable for particles dispersed in the dispersion medium; b) providing a particle dispersion comprising the dispersion medium and particles dispersed therein in the first semi-chamber, the particle dispersion being distributed substantially homogenously in the first semi-chamber; c) generating a pressure gradient between the first and the second semi-chamber such that the pressure gradient in the first semi-chamber causes a particle dispersion flow directed towards the partition; and d) depositing a particle aggregate material comprising geometrically compact particles on the partition by transporting a dispersion agent into the second semi-chamber.
