Abstract
Over the last few years, Additive Manufacturing, or as it is sometimes known, 3D printing, has become a significant research field for researchers worldwide. The necessity to increase the strength of materials and minimize their weight in the automotive and aviation industries has urged engineers and scientists to conduct more investigations and identify manufacturing methods to replace the classical ones. Additive manufacturing involves building a geometry layer by layer from a wide range of materials, which helps to utilize materials efficiently while minimizing the amount of waste produced as well as build complex, large geometries and light-weight components. Furthermore, it minimizes fabrication and processing times. In this paper, three different alloys were printed (TiAl6V4, AlSi10Mg and 316L) using MSC Simufact software to investigate the effect of changing machines on the effective stress and surface deviation. Furthermore, thermal analysis as well as mechanical, thermal and thermomechanical calibrations were carried out to determine a parameter set consisting of the laser power, inherent strains, fraction of exposure energy and volumetric expansion factor.
Highlights
Over the last three decades, research into printing technology/additive manufacturing (AM) has progressed from fast prototyping to Industry 4.0 [1, 2]
Given that AM depends on many factors to determine the required parameter set to produce the desired part, e.g., laser power, fraction of exposure energy and volumetric expansion factor, experimental tests should be conducted to measure these parameters
Different types of 3D printing machines are available using this piece of software, e.g. two kinds of Electro Optical Systems (EOS) have been used, namely M280 and M400, the size and power of both differ
Summary
Over the last three decades, research into printing technology/additive manufacturing (AM) has progressed from fast prototyping to Industry 4.0 [1, 2]. After many editions of SLA machines in the early 90s, new AM principle technologies were launched, namely solid ground curing, fused deposition modeling and laminated object manufacturing [3, 4]. This development was followed by many years of continuous improvement in AM technology, from resin to metal powders and from non-functional molding applications to the fabrication of medical implants [5]. AM methods have been characterized in the literature based on a variety of parameters, including direct or indirect process technology, the state of the raw materials, and the materials used. After the components in the first layer have been bonded together using glue or heat, the second layer
