Abstract: 
The research conducted as part of this thesis shows that 3D concrete printing is not primarily compelling due to blanket cost advantages over conventional masonry construction, but rather because of a fundamentally altered cost and process structure. Whilst labour and material costs dominate in traditional construction methods, 3D printing is heavily driven by investment and equipment costs. Cost-effectiveness therefore depends largely on the utilisation rate of the printing system and its strategic integration into serial or integrated construction concepts.
The construction process is becoming more industrialised and requires increased process stability as well as technical monitoring. Economic benefits arise in particular when the geometric and design freedom of the additive process is utilised in a targeted manner.
Overall, the study illustrates that concrete 3D printing should be understood not so much as an isolated construction alternative, but rather as an integral part of a digitised and systemically transformed construction process.
