    • A method of manufacturing a grid (1) for selective transmission of electromagnetic radiation, particularly X-rayradiation, 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.
    • 提出了制造用于选择性地传输电磁辐射的电网(1)的方法,特别是X射线辐射。 该方法包括:提供具有自支撑稳定性的支撑元件(3),其中支撑元件(3)由基本上不吸收电磁辐射的材料制成,以选择性地透过网格; 在所述支撑元件(3)的表面上施加金属层(5); 以及通过吸收电磁辐射的材料在所述金属层(5)的表面上建立选择性透射结构(7)以选择性地透过所述栅格,其中所述透射结构使用选择性激光烧结来构建。 由于支撑元件(3)提供足够的机械稳定性但不吸收相应的辐射,所以使用选择性烧结的选择性透射结构(7)可能不必随后与制造基板分离,从而防止分离/切割损失, 此外,可以在结构上保持和保护在处理电网期间的损坏。
