Have produced a study on the automation of 3D printing construction, while also investigating methods of improving the process in regards to the rheological properties of the concrete mix.
Specifically, the study details the application of additive manufacturing technology in the fabrication of a building wall model, in which the door opening was finished with an automated lintel installation. A lintel is a beam placed across openings in buildings like doors, windows etc. to support the load from the structure above.
The objective of the study was to improve the low capacity of 3D printed concrete mixes to transfer loads, which can be particularly troublesome in cases of external components that need to be placed on top such as precast lintels or floor beams during 3D printing construction processes.Such an investigation, according to the researchers, can prove beneficial in designing larger civil structures using concrete 3D printing technology.
