“…Approximate values in (Table 2) are close to the exact values from the first iteration. A priori knowledge of the behaviour of the system proves to be very influential in the speed of convergence of the method (Peres and Martin 1999). …”

“…The product is provided with adding layers until the last layer is completed while in traditional manufacturing desired product can be obtained via removing materials from parts [2][3][4][5]. 3D printing technology due to overcoming the many difficulties and limitations of conventional fabrication approaches takes attention in many industries such as aerospace, automotive, medical, building industries, fashion and fashion accessories [6][7][8]. This technology allows fabricating complex structures in a controllable manner with desired architecture and porosity, enables designers and engineers to create unique products that can be manufactured at low volumes in an economical way [9][10][11] and provides advantages such as less waste, freedom of design and automation, saving of material and energy, environmental/ecological advantages [12][13][14][15].…”

This paper investigates the manufacturing variants influential on the strength of 3D printed products. In contrast to the traditional manufacturing methods which produce the final product via removing materials from parts, in 3D printing technology the products are provided with adding layer by layer directly from a digital file. 3D printing technology due to overcoming the many difficulties and limitations of conventional fabrication approaches is a rapidly progressing technology which takes attention in many industries such as aerospace, automotive, medical and building industries. This paper aims to research the variants affecting the mechanical properties of components produced by 3D printing technologies. To reach this aim a comprehensive review was conducted to determine the various process and geometric parameters in 3D printing technologies. The conducted literature survey results indicate that besides the filament material, the nozzle speed and diameter, layer thickness, filament diameter, printing raster angle, printing pattern, temperature and infill density are parameters which influence the final product quality and mechanical properties in term of ultimate tensile strength, yield stress and elasticity modulus. It is concluded that 3D printing filament materials strength has direct affect on the strength of final product. By providing the adequate thermal behavior of the system, the cohesion between layers can be improved. Extrusion speed affects surface roughness and quality of the produced components. Nozzle diameter has a significant influence on interlayer cohesion. The honeycomb pattern due to facilitating the load transfer between layers provides higher mechanical strength. Findings of this study will guide the researchers and manufacturers to select appropriate printing parameters to produce component with optimum mechanical properties.
