A method is disclosed for producing a 2D collimator element for a radiation detector, in which crossing webs made of a radiation-absorbing material are formed, layer-by-layer, by way of a rapid manufacturing technique. In at least one embodiment, the webs are aligned along a &phgr;- and a z-direction and form a cell-shaped structure with laterally enclosed radiation channels, at least in the inner region of the 2D collimator element. In at least one embodiment, the invention moreover relates to a 2D collimator element for a radiation detector that has such a layered construction. This allows the provision of a very precise and rigid collimator arrangement which, at the same time, has a high collimation effect.
