Abstract

As 3D Concrete Printing (3DCP) technology develops, requirements on the form and surface quality of the final products are increasing. Layer-wise deposition results in the so-called ‘staircase effect’ which can lead to limitations on the attained precision and accuracy of geometries. Applying other shaping processes with a higher manufacturing precision can be deployed to combat this and milling is one example that has been shown to yield benefits. This paper presents an early trial of a milling process applied after printing and before the final hardened state of the material. A case study of a panel component is presented and observations are reported, which include: the critical nature of the material state, the control of debris and milling path sequence and direction. Insights are formulated into a three-tier structure to help develop signpost issues for the development of the approach.
