(57) A concrete 3D printing apparatus, for constructing buildings and structures, comprises a primary manoeuvring arm, a secondary manoeuvring arm, a support base and a linear translator setup. The primary and secondary manoeuvring arms are adapted to move rotationally along the horizontal plane. The distal end of the secondary manoeuvring arm is movably attached to a frame of linear translator through a mounting plate. The holding provision is attached to bottom of the frame of the linear translator. The linear translation mechanism of the linear translator is partially coupled to the mounting plate by mechanical means. The frame of the linear translator is actuated to move along the vertical plane to span the vertical range of the print head movement. Stabilisation mechanisms and load balancing provided for the stable movement of linear translator and the gravity load on the manoeuvring arms both at rest and during operation.
