On the Question of Mix Composition Selection for Construction 3D Printing

Abstract

Due to its novelty, futuristic appearance of created forms, a vivid contrast with a conventional image of a construction site, construction 3D printing attracts attention of a wide audience. Specialists see it as affording significant possibilities for saving all kinds of resources, reducing construction time, giving possibility to implement progressive design solutions, but they also see serious problems, such as: an immature general concept of development of additive technologies, a limited range and high cost of consumables, lack of methods for development of new compositions and lack of experience in application of such methods as a result. The paper analyzes links between the process factors and properties of molding components; principles of their practical implementation are proposed. Special attention is given to the issues in assessment of construction printability of newly-developed compositions.
