Abstract

This project introduces a multi-colour 3D printer designed to create complex objects with enhanced visual appeal and functional colour differentiation in a single print cycle. The system features a central controller managing multiple subsystems, including colour feeders, motion control units, and thermal management. Stepper motors with dedicated drivers control the X, Y, and Z axes, alongside an additional extruder motor for precise multi-colour filament feeding (up to four colours). A touch-enabled graphical display offers an intuitive interface, while Wi-Fi and SD card modules provide seamless file transfer and remote control. Integrated camera and flash modules enable real-time monitoring and documentation. The hotend, supported by a motor-driven cooling fan and thermistor feedback, maintains consistent extrusion quality. This design improves printing flexibility, reduces post- processing, and expands creative possibilities, making it ideal for prototyping, education, and artistic use. Its integration of multiple advanced features delivers both efficiency and versatility in additive manufacturing.
