GRID AND METHOD OF MANUFACTURING A GRID FOR SELECTIVE TRANSMISSION OF ELECTROMAGNETIC RADIATION, PARTICULARLY X-RAY RADIATION FOR MAMMOGRAPHY APPLICATIONS
A method of manufacturing a grid (1) for selective transmission of electromagnetic radiation, particularly X-ray radiation, is proposed. The method comprises: providing a support element (3) having self-supporting stability, wherein the support element (3) is made with a material which essentially absorbs no electromagnetic radiation to be selectively transmitted through the grid applying a metal layer (5) at a surface of the support element (3) and building a selective transmission structure (7) at a surface of the metal layer (5) with a material which absorbs electromagnetic radiation to be selectively transmitted through the grid, wherein the transmission structure is build using selective laser sintering. As the support element (3) provides sufficient mechanical stability but does not absorb the respective radiation, the selective transmission structure (7) build thereon using selective sintering might not have to be subsequently separated from a manufacturing substrate thereby preventing separation/dicing losses and, furthermore, might be structurally held and protected against damage during handling of the grid.
