Research Objectives
Metal powder is very difficult to deal and additive manufucuturing using metallpowder is difficult to laminate a big parts in short time. Therefore, to achive big volume lamination swiftly and easily, we develop additive manufucturing technology that lamination material is supplied solid like metal wire.
Research Results
We can laminate narrow width wall by suppling metal wire on llaser irradiation point and layer upon layer. In this process, lamination speed is 4kg/h. To achive higher llamination speed, we develop hot wire DED system. And lamination speed of hot wire DED system achieve 8.1kg/h. this lamination speed indicate that lthis machine can laminate big volume lwith high speed.
The process behavior of wire DED was obserbed that wire suppied molten pool and melted by laser irradiation stably. this stable behavior was continued during DED process.
In addition, we can make lnot only liner wall but also circler wall using developed wire DED machine.
