摘要
Purpose This paper aims to present an experimental and theoretical study oriented to investigate the potential use of localized microwave-heating (LMH) in 3D-printing and additive-manufacturing (AM) processes. Design/methodology/approach Following a previous study by the authors, a magnetic confinement technique is developed here as a non-contact support for the incremental solidification by LMH of small metal-powder batches. This approach, which saves the need for a mechanic support in contact with the powder-batch during the microwave heating, may significantly simplify the LMH-AM process. Findings The powder properties are characterized, and a theoretical LMH model is used to simulate the LMH mechanism dominated here by magnetic eddy currents. Originality/value The experimental products are analyzed, and their hardness, porosity and oxidation are evaluated. Practical considerations and further improvements of the non-contact LMH-AM process are discussed.
