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. Keywords: 3D Concrete Printing, Cast-in-Situ Technology, Pre-Cast Technology, Pre-Stressed Technology, Post-Tension Technology, 3D-Printable Materials, Extrudability, Buildability, Workability, Open Time, Contact Strength between Layers, Aggregates, Water-Cement Ratio, Rheological and Mechanical Properties of 3D Printable Materials, Reinforcement Strategies, Printability Window, Cost Analysis, Green Concrete, Self-Healing Concrete.
