Metallurgical and Manufacturing Services develops its wire

"Parts produced with WAAM are particularly notable for their high density and strong mechanical properties, which are comparable to parts manufactured with traditional manufacturing methods." "As the wire feedstock is a 100 per cent dense input material, there is negligible porosity induced in the fabrication process, leading to a very dense final part."

Corrosion, Contact Resistance, and Surface Characteristics

First, the effects of manufacturing conditions on formed bipolar plate quality and process repeatability were investigated. Second, corrosion and contact resistance tests for manufactured bipolar plates as well as blank stainless steel sheets were performed.
