Abstract

This paper presents a solid freeform fabrication (SFF) technique based on micro-plasma powder deposition (MPPD). The relationship between the geometric features of the deposited layers and the welding parameters is investigated. The arc length is controlled through the monitoring of the arc voltage. The result of building parts with functionally graded components by the MPPD process is shown as well. The microstructure and the properties of the deposited layers are analyzed. The experimental results show that the MPPD process is a promising welding-based solid freeform fabrication technology.
