تنفيذ المباني بتقنية الطباعة ثلاثية الأبعاد نحو تحقيق أهداف التنمية المستدامة في مصر

الملخص EN

The construction industry is one of the most important and largest industries in the world, and studies estimate that the total cost of the construction industry in the world is about 10 trillion dollars annually, which represents 13% of the gross domestic product in the world.

Despite the amazing progress in various industrial fields due to the use of modern technologies and computer applications, the construction industry has not kept pace with that progress compared to other industries, due to its direct dependence on the human element.

Over the course of the last century until the present time, the steps for building construction are still done manually, starting with the excavation process, despite the equipment that has been developed, but it needs trained labor to operate that equipment, passing through insulation and regular and reinforced concrete works, building works, sanitary works and electricity until reaching the finishing stage.

Which prompted the international research centers specialized in the construction industry to study the development of new methods of construction characterized by sustainability and environmental preservation - by reducing waste resulting from traditional construction methods while recycling a large part of that waste and using it again in the construction process - on the one hand, and it is also a fast technology And labor-saving on the other hand, which will directly reflect on the quality of the final product and reduce the implementation time significantly in addition to reducing the total cost of the building.

The technology of 3D printing of buildings is the latest of these methods, which can achieve these goals.

Construction industry experts expect this technology to impose itself strongly in the coming years and to replace traditional building methods within a period of time not exceeding ten years.

This research paper deals with this technology in terms of its advantages and disadvantages compared to traditional methods, with a review of a group of Arab and international buildings implemented by 3D printing in order to reach how to apply it in the Arab Republic of Egypt in line with the ambitious comprehensive development plan that is currently being implemented in full swing.
