Abstract:
This diploma thesis analyses the construction process disruptions and risks of concrete 3D printing in the construction industry as well as suitable measures to overcome the associated problems. Based on the practical experience of the Steinhoff architectural office, the main problems in the construction process are analysed and possible solution strategies are developed. Both organisational and technical measures are examined. Sensors on the machines enable technical faults to be recognised at an early stage. Precise weather data can support the adjustment of the printing process and the determination of the aggregates in the concrete mix. Efficient planning and adaptation of the construction process is made possible by integrating a holistic BIM approach. This reduces interface problems and shortens the preparation time for the printing process. One way to improve occupational safety in the printing area is to use additional robots for work during the printing process. during the printing process. Post-treatment agents or a layer of exposed concrete can be applied to optimise the surface quality. Economic aspects are also considered, such as the optimisation of printing times by printing in a layer system in order to improve the overall cost-effectiveness of 3D printing projects in the construction industry.
