The construction industry is facing a drastic change in standard processing technologies and many construction automation methods such as 3D concrete printing (3DCP) merged in the construction field. 3DCP can allow flexible construction without the use of much expensive structure and materials. 3D concrete printing is an innovative construction method and has many advantages in the construction field such as reduction in construction time, reduction in cost, flexibility in designing, reduction in errors and environmental factors. Concrete is extruded through a nozzle and layer-by-layer concrete plates are formed to construct the model without the mold. Studies has been done to detect and resolve various design and operational problems faced in 3D concrete printing which would help in future development of the construction process. Goal of this project is to built an efficient and low-cost hardware structure which will print a 3D concrete cube using an algorithm. In this CNC machine, the XYZ movement controlled by an ARM microcontroller (LPC 1769) with software implemented on LPCXpresso using embedded C. The microcontroller converts G-code which was transmitted by UART from PC into machine language instruction which is to be sent to the motor driver of the CNC printer to print the model.
