With additive manufacturing or laser-sintering, components with the highest material requirements can be manufactured. Compared to traditional ablative manufacturing processes such as cutting, turning, drilling or milling, additive manufacturing is determined by the design. Physical or chemical hardening or melting processes take place during assembly. Typical materials for additive manufacturing are plastics, synthetic resins, ceramics and metals. Although these are often forming processes, a concrete product does not require any special tools which have stored the respective geometry of the workpiece, such as casting moulds.
