    • One or more metal printing techniques are described for generating a three-dimensional metal structure, such as a one-dimensional or two-dimensional anti-scatter grid. The techniques comprise applying a thin layer of powdered metal onto a printing area and using a binder (which is printed onto the printing area according to a specified pattern) to bind the powdered metal particles together. The acts of applying powdered metal and a binder may be repeated a plurality of times until a three-dimensional metal structure having a specified height is created. Moreover, in one embodiment, once the layering is complete, another binder is applied to the one or more layers to provide strength and/or support. While heat may be used in some embodiments to activate one or more of the applied binders the three-dimensional metal structure is generally not heated to a melting point of the powdered metal.
    • 描述了一种或多种金属印刷技术,用于产生三维金属结构,例如一维或二维防散射网格。 这些技术包括将粉末状金属薄层施加到打印区域上并使用粘结剂(根据指定图案印刷在印刷区域上)将粉末状金属颗粒结合在一起。 施加粉末金属和粘合剂的动作可以重复多次,直到产生具有特定高度的三维金属结构。 此外,在一个实施方案中,一旦层叠完成,将另一粘合剂施加到一个或多个层以提供强度和/或支撑。 虽然在一些实施方案中可以使用热来活化一种或多种所施加的粘合剂,但是三维金属结构通常不被加热到粉末状金属的熔点。
