The book presents a detailed comparison between traditional construction techniques and 3D printing construction. The comparison focuses on four primary parameters: mechanism, composition, time and cost. The operational details of each technology (cast-in situ, pre-stress, post-tension) are reviewed and comparison criteria for all techniques are formulated. In conclusion, 3D printing seems to be well on its way to transform the whole construction industry.
