Development of pattern driver for piezo nozzle control of multi-print head in 3D SFFS using UV resin

Three dimensional printing (3DP) process is one of the RP process technology that can fabricate three dimensional parts by jetting UV resin through piezo nozzle of print head in 3D SFFS using UV resin technology. As this technology uses multi-nozzle, it can make high speed fabrication. It sends 3D computer-aided design (CAD) data to a print head and it produces 3D solid freeform fabrication (SFF). In this research, the pattern driver which is developed. In this research, controls each piezo nozzle of multi-print. The three dimensional freeform data is used to jet resin on build tray of SFF system. And z table is controlled so that piles up regular thickness. The x-y table of SFFS to move the multi-print head should satisfy high speed and high accuracy. The proposed print head consists of 4-heads for UV resin and 4-heads for support material for fast fabrication. The system between control system and multi-print head for the SFFS is also integrated.
