It is a construction technology that can be poured without Rapid production, use in construction activities It provides advantages such as convenience.
Bu yeni üretim teknolojisinin en önemli yenilikçi hedefi, çok kisa sürelerde istenilen kalite düzeyine sahip yapi elemanlari ve konut insaatlarinin yapilabilmesini saglamaktir. The most important innovative goal of this new production technology is the desired quality in a very short time. It is to ensure that building elements and housing constructions with the highest level can be made.
Insaat sektörü gürültü, toz ve zararli emisyonlarla büyük ölçüde çevreyi olumsuz yönde etkilemektedir. Üç boyutlu yazici teknolojisi ile üretim süreçlerinin gürültü, toz ve zararli emisyonlar olmadan insaat imkani saglamaktadir.
