Development of 3D printer with integrated temperature control system

This paper presents the conceptual design and implementation of a cost effective 3D prototyping machine which encompasses the design of mechanical, electrical & electronics systems as well as integrated Software in order to create a workable prototype. The objective of this research is to design and develop a machine which is controlled by a computer and capable of producing 3D solid representation of a CAD model in plastic via plastic extruder. A XYZ axes system is developed in order to enable the machine to carry out the prototyping process efficiently and effectively. A control system for the stepper motors and heating actuator are also developed to satisfy the precision requirement of this machine. The total system covers the conceptual design, the development process and the integration of the mechanical system and electrical and electronic systems of 3D prototyping machine. Main focusing point of this paper is to design and develop the suitable temperature control system of 3D Rapid Prototyping Machine (RPM).
