The final goal is to develop a process chain that provides ready-to-use parts of industrial quality at moderate investment cost. This includes a 4-axis milling machine for green and final machining of the as-printed and sintered parts and a compact furnace for debinding and sintering. This paper reports about ongoing work in the funded joint project ""AMCC Line"". A thermoplastic filament with a high metal powder loading of 55 vol% was developed and successfully processed on commercially available FFF printers. In order to achieve near full density metallic parts, a debinding treatment is required that removes the organic constituents. Subsequently, the individual metal particles are joined by diffusion in the solid state (sintering) and a fully metallic part is obtained. It was possible to print and heat-treat different parts in stainless steel 316L. Examples of achievable geometries and a strategy for dimensional and mechanical property monitoring is presented that provides information about the industrial viability of this process chain.en620660671Manufacturing and properties of metal parts made by fused filament fabricationconference paper
