Infill can be classified as fixed infill or variable infill. It is possible fixed infill to have a role of a guide for variable infill. This paper aims to clarify the effectiveness of the fixed infill role when installing and changing variable infill using data from the experiments of installing and changing infill conducted in the ‘Infill Laboratory Glass Cube’ located in NEXT21.
The results of the experiments are as follows; 1) The fixed infill role was effective when we change the variable infill arrangement without adjusting between the next variable infill. 2) The fixed infill role was effective when not only specialists change variable infill but also non-specialists change.
