Reducing the material consumption of stucco decorations based on information technology

The use of modern additive technologies through the automation of the process of creating moulds and manufacturing moulded decorative elements allows for a reduction in material costs for construction work. However, the task of minimising the consumption of building materials is not fully solved. The paper describes an attempt to improve mould creation methods using parametric modelling, photogrammetry, and 3D printing. The authors provide a classification and list of the most common stucco decoration elements. The paper discusses algorithms and features of script development for obtaining digital models of basic types of moulds. To create flexible forms of complex configuration, the authors suggest using spherical objects – metaballs. Based on parametric algorithms, the result is obtained in the form of polygonal models ready for 3D printing. The proposed method of creating forms allows for more accurate prediction of the consumption of building materials and significantly facilitates the work of contractors.
