DEVELOPMENT OF A HIGH-FILLED FILAMENT USED IN MFDM TECHNOLOGY

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.

WAYS OF APPLYING 3D PRINTING TECHNOLOGIES IN THE CREATION OF MODERN ARCHITECTURAL OBJECTS

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.

FEATURES OF PROCESSING OF POLYLACTIDE COMPOSITES WITH USE IN 3D PRINTING. REVIEW

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.

NEW TECHNOLOGIES IN THE FIELD OF CONSTRUCTION. USING 3D PRINTERS

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 effects of infill patterns on the mechanical properties of 3D printed PLA parts fabricated by FDM

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.

Development and investigation of device for processing polymer materials by 3D-printing method

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.
