The article examines the evolution of rapid construction methods, starting from traditional techniques and ending with modern innovative technologies. Today, most people prefer houses built in the traditional way; however, this trend is changing due to the growing popularity of prefabricated constructions. This is driven by the economic efficiency and speed of erecting such buildings.
The article provides an analysis of current approaches to 3D printing of buildings. It focuses on three key areas: 1) computer-aided design methods for 3D printing of buildings; 2) manufacturing methods and materials used; 3) methods for evaluating their effectiveness. The section "Design/Development" covers tools and techniques used from the design stage to the production of building elements. The Technology and Materials section looks at opportunities for engineering applications, categorized by material type.
The article describes the research in which a filament highly filled with Co-Cr-Mo alloy powder was developed, the 3D printing process, and the degradation and sintering of the produced samples. The research shows the influence of debinding on the final structure of the material. The research presented in this article allows us to assess the relationship between the particle size of the metal powder and the surface and internal structure of the finished sinters.
The authors analyzed the available technological solutions for 3D print in the process of constructing real architectural structures; presented the relevant data on technical parameters of the contemporary three-dimensional printers; the problems for the development of the technology have been conceptualized, as well as the choice of optimal materials and engineering structures with regard for peculiarities of selected methods of layer-wise extrusion or making buildings parts with their further assembling into the final structure.
The most common additive methods of processing polylactide materials are analyzed. Attention is paid to the features of methods of selective laser sintering, stereolithography and modeling by layer surfacing, as well as the advantages and disadvantages of using biodegradable materials, including polylactide. Approaches to the development of composite materials based on polylactide with additives of different nature and their technological and operational characteristics are substantiated.
Technological processes in all branches of production are maximally automated in the world, this also applies to construction. The main driver of automation of construction processes is 3D printing technology. The first driver was the invention of stereolithography technology, which was discovered in 1986 by American engineer Chuck Hull. The article describes the process of 3D printing technology, using different materials and printing principles.
The purpose of this study is to analyze the effect of the infill pattern on the mechanical properties of 3D printed PLA parts. Polylactic acid (PLA) parts were fabricated by fused deposition modeling (FDM) at various infill patterns at 30% infill density. Five different infill patterns (stars, 3D honeycomb, honeycomb, gyroid, Hilbert curve) have been investigated.
The analysis of the current state of 3d industry and prospects for its future. In the work, calculations were made and graphs of dependence were obtained, which influence the work of the auger and the installation itself. A new method of printing parts with polymer granules is described and the principle of operation of the equipment used is described. The picture of the working installation with the main components and the method of its attachment on a 3D printer is presented.
