Additive manufacturing, also known as 3D printing, is becoming a new trend in construction. Many disciplines have perceived this technology as the advent of the third industrial revolution. It is in manufacturing, development, and architecture that 3D printing will have the greatest impact on the construction industry. Unlike the traditional method of construction which has low productivity and stunted technological capabilities; 3D printing concrete provides low cost, fast construction with automation, and greater freedom of design and architecture. This construction technique is mainly beneficial as there is no need for formwork. The estimated cost of the formwork is between 35 to 60% of the overall cost of construction. Therefore, 3D printing represents a significant financial solution and improves safety. Moreover, this innovation improves construction times and frees up architectural gestures by offering a wider possibility of shapes. Designers and architects can now print 3D buildings from materials such as mortar or concrete.

The aim of this project is to optimise the effect of mix composition of 3D printing made with local natural fibres and shape modifying agents on the fresh and rheological properties, the buildability, the mechanical performance, durability, and structural behaviour of prototype samples made with 3D printing concrete.
