Post Processing

Published on 16 February 2021

After the parts have been printed, they need to be separated from the building platform. This is typically done by mechanical cutting or via electric discharge machining.

To reach the optimal microstructure and high coercivity of Nd-Fe-B magnets, post-process heat treatments are applied after 3D-printing.

Even as 3D-printing is a near-net-shape manufacturing process, surfaces requiring precise dimensions or excellent surface finish need to be machined to tolerances.

Magnets are coated either with nickel or epoxy based coatings to provide protection against corrosion

Finally, the magnets are magnetized
