Metal Materials

Short Description:

Metal powders are metals that are reduced to fine particles and are the preliminary base materials for most 3D printing processes that produce metallic parts. 3D printing, also known as additive manufacturing (AM), is the manufacturing of parts and products in a layer-by-layer fashion. Both the characteristics of the metal powder and the type of the 3D printing process determine the properties of the end product. Powder characterisation takes place depending on the way it is produced, which may result in different particle morphology and purity.
