Robotized Method for Manufacturing Individual Concrete Elements with Specific Shapes

Wood and combinations of wood and plywood is the most traditional formwork in mould-based shaping of construction components. This kind of formwork usually doesn't include curvatures, but favours straight lines and sharp corners yielding in angular shape concrete building blocks. In this paper we describe a novel robotized method for manufacturing individual concrete elements with specific shapes. It is based on utilization of a digital 3D model of the target object, from which mould machining paths for the robot are stepwise created to prepare a mould made with hardened sand. Also casting of concrete blocks is described with an example.
