Study on methods for verifying the shape and quality of construction 3D printers

Abstract

In recent years, the use of construction 3D printers has been increasing in civil engineering projects directly managed by the Ministry of Land, Infrastructure, Transport and Tourism, but currently there are no regulations on how to check the finished shape or quality. In this report, we summarize the implementation status of finished shape and quality control in cases where construction 3D printers have been used, and report on the status of the study toward formulating a method of checking the finished shape and quality that takes into account the characteristics of construction 3D printers.
