State-of-the-Art Review on 3D Printing Technology Applications in Construction
This thesis presents a state-of-the-art review on the 3D printing technology and its
applications in construction. This technology is the computer aided design and manufacturing of
objects. It is a new way of manufacturing products by layer to layer adhesion. The material can
include thermoplastics, photopolymers, concrete and many other materials. The major benefit of
3D printing applications in construction is the ability to 3D print concrete without the use of
formwork. The use of concrete 3D printing allows for the construction of concrete structures that
are cost and time efficient. Construction of concrete 3D printing deviates from typical methods of
concrete construction and therefore requires structural analysis and novel engineering design to
maintain structural integrity. A review of concrete 3D printed structures that are currently being
printed and how 3D printing works are presented in this thesis to allow for informed design
decisions when 3D print structures. The overview of the 3D printing will also include the
feasibility of 3D printing structures on planet Mars. Due to the autonomous nature of 3D printed
construction, structure can be constructed on the desolate planet before astronauts arrive to Mars.
The use of 3D printing has a variety of applications and can increase the efficiency of structural
engineering design and construction.
