Mechanical properties of PLA based closed porous structures manufactured using FDM process

Abstract

PurposeThe purpose of this article covers the design and manufacture of porous materials that can be used in different engineering applications by additive manufacturing.Design/methodology/approachThe most important design parameters of the porous materials are the cell structure and wall thickness. These two design criteria are difficult to control in porous materials produced by conventional production methods. In the study, two different wall thicknesses and four different pore diameters of the porous structure were determined as design parameters.FindingsA compression test was applied to the produced samples. Also, the densities of the produced samples were compared. As a result of the study, changes in mechanical properties were observed according to the cell wall thickness and pore size.Originality/valueThe originality of the study is that, unlike traditional porous structure production, the pore structure and cell wall thicknesses can be produced in desired dimensions. In addition, a closed pore structure was tried to be produced in the study. Studies in the literature generally have a tube-type pore structure.

“…There are studies on the mechanical properties of parts fabricated using FDM (Banjanin et al, 2018;and Rajyalakshmi and Boggarapu, 2019;Birosz et al, 2022;Yavuz and Yildirim, 2023;Bayraklilar, 2023). Saad et al have presented various approaches, such as response surface methodology, particle swarm optimization and symbiotic organism research, to find the optimal parameter settings for better surface quality, i.e., surface roughness of the FDM printed part (Saad et al, 2019).…”
