Evaluation of Metal Powder for Additive Manufacturing of Margaring Steel

Abstract

Additive technologies enable the creation of complex shapes and structures virtually unattainable using classical production processes. These technologies allow components to be produced not only from paper or plastic, but also from composite materials or metals, with the same or even better properties than their predecessors made by machining or forming technologies. However, for customers who are not specialists in these technologies it may often be difficult to orientate themselves in the wide range of options and take full advantage of the potential of these technologies. As a rule, production process parameters are not as decisive as final product characteristics, especially the price, quality and delivery date. Therefore, this article tries to answer elementary questions that customers might have when considering production using additive technology, and to describe its specifics and possibilities. Special attention is paid to metal 3D printing, whose specifics are illustrated using the example of printing a simple component in various ways, in different quantities and sizes. The article documents an experiment conducted under real conditions using DMLS (direct metal laser sintering) technology, which shows how different ways of printing affect the price, the processing time, and the quality of the final component.

Co2 Laser Powered Metal 3D Printer Parameter Influence on Part Quality

“…This material grade is widely used in additive manufacturing industry because it has good mechanical properties and it is one of the least expensive materials. [3] SS316L powder has been produced by Höganäs AB, this powder is with average grain size from 20 -50 µm. Experiments have been performed on Aurora Labs Titanium Pro S1 metal 3D printer.…”

Characterization of Materials Used in 3D-Printing Technology with Different Analysis Techniques

“…To characterize the material, the most used techniques, selected by their usefulness, are generally SEM-EDX, Raman Spectroscopy, X-Ray Diffraction (XDR) or Dumas Analysis [11] [12] [13]. The present work studies the real chemical composition and physical properties (microstructure and morphology) of raw materials, using the techniques advised on the bibliography and others complementary techniques (ICP-OES; FTIR), in order to know the properties of raw materials, with the aim of finding different applications for this material using 3DP technology.…”
