Whether reinforcement is required or not is determined at the design stage when calculating the strength of the structure. The type of reinforcement, its diameter, the horizontal and vertical laying step, the method of binding or welding are determined. It can be reinforced horizontally during printing by laying reinforcement between layers and sealing it, or between printed elements when assembling them on the foundation, and vertical reinforcement is performed in the cavity of the walls before pouring concrete or foam compounds.
