Researchers studied different types of 3D printers,
materials, and construction procedures to take this tech-
nique forward to construct structural components and/or
whole structure [3]. Tay et al. [4] presented the previous
researches conducted in 3D printing. Eight categories of
research topics, namely, printing techniques analysis,
material analysis, control system, data analysis, architec-
tural design, literature review, concept analysis, and cost
benefitanalysiswereobserved.Bosetal.[5]presentedthe

Eindhoven University of Technology. In addition, the 3D
concrete printing was described in terms of geometry,
conducted experimental research, and the difficulties of
construction.
