Abstract


Additive Manufacturing (ADAM) is a layered process based on metal-based material extrusion that was patented by Markforged company. ADAM technology is a sequential additive manufacturing process that uses a metal powder fiber with a wax binder as a binding agent. The plastic binder is removed by leaching and vacuum sintering after the semi-finished product has been formed by the layering process. The outcome of the research aims to provide the basic technological characteristics of the ADAM process using the Metal X device, as well as to compare the given processes to the Selective Laser Melting (SLM) technology. This technology combines a new unique process and the current laser sintering method. To be more specific, the density, structure, strength, and hardness of the applied material 17-4 PH are analyzed. Subsequently, the samples' dimensions and shape specifications, as well as their surface structure are identified. The ISO IT classes of the reference artefact are used to assess the dimensions and shape accuracy of the ADAM additive process.
