3D printing offers a promising future in construction, but there is still a long way to go before it is used
in everyday applications, as the material characteristics are still poorly understood. This was the focus of
my thesis. I focused on the mechanical properties of eleven different filaments, PETG, PLA, PINE,
CORK, BAMBOO, SILK, FELX 98-A, ABS, PETG-CF, PET-CF and PLA-CF. In order to obtain
comparable results, I used 100% fill with layers of lines that were perpendicular to each other, with the
initial layer at a 45° angle. First, a walk through the origins and further history of 3D printing, followed
by a brief look into the future. Some of the more common 3D printing methods are described next. Then
the filaments used are described, as well as the process of preparing them for printing. In the fifth part,
the 3D printing process is presented, followed by the flexural test procedure. Both were carried out at the
Faculty of Civil Engineering and Geodesy, University of Ljubljana. The end brings an analysis of the
results obtained.
