Abstract: To develop large-scale RP systems used to producing functional parts and large-sized models has become an urgent call now. In this paper, a large-scale RP system, MEM600-I, based on the melted extrusion manufacturing (MEM) process has been developed successfully. And the key issues to develop such a system are discussed. Based on the actual forming experiment, it is concluded that the MEM600-I works reliably and the forming efficiency is much higher than its parallel equipments.

Key words: Melted extrusion manufacturing, Large-scale RP systems, Forming efficiency
