“…The authors of that research also indicate correspondence of their results with previous studies [17]. However, experiment settings in [12] and [17] have significant differences that impede direct comparison. For example, [17] scrutinizes ABS samples printed on a proprietary Stratasys Vantage machine.…”

“…However, data for samples printed with 0.4 mm nozzles come into conflict with results of previous research [12]. That study claims that increasing layer height also increases sample strength instead of drastic reduction: "In upright samples, tensile and flexural strength increased as layer thickness increased".…”

“…In the majority of papers observed [5,[10][11][12][13][14], testing standards used have been developed for polymer samples produced by molding or by machining or die cutting out of monolithic sheet or slab [16] and, consequently, not considering the specifics of samples made of fused filament threads.…”

“…The strength of FDM (FFF) parts across the layers (in Zdirection) is significantly lower than the strength along the threads (x and y-direction respectively) sometimes by a factor. In the majority of studies investigating the influence of various parameters on the strength of FDM (FFF) technologies [5,[10][11][12][13][14], tensile properties are measured on flat samples oriented horizontally during the printing process to be researched, i.e. with the smallest dimension in the Z axis.…”

The current paper is studying the influence of geometrical parameters of the FDM (FFF) 3D printing process on printed part strength for open source desktop 3D printers and the most popular material used for that purpose, i.e. PLA (polylactic acid). The study was conducted using a set of different nozzles (0.4, 0.6 and 0.8 mm) and a range of layer heights from the minimum to maximum physical limits of the machine. To assess print strength, a novel assessment method is proposed. A tubular sample is loaded in the weakest direction (across layers) in a three-point bending fixture. To explain the results obtained, a mesostructure evaluation through SEM scans of the samples were used. A significant influence of geometric process parameters was detected on sample mesostructure and, consequently, on sample strength.

“…There are three different types of orientations: horizontal, vertical and perpendicular [4]. In the present study, all samples were printed in the horizontal build direction only since most studies [7,[30][31][32] have reported on the superiority of mechanical properties for both horizontal and vertical directions compared to the perpendicular direction. During the printing process, an extruded filament would be printed at a certain layer extrusion path, otherwise known as raster orientation.…”

Abstract. This paper addresses the utilisation of fused deposition modelling (FDM) technology using polyamide 12, incorporated with bioceramic fillers (i.e. zirconia and hydroxyapatite) as a candidate for biomedical applications. The entire production process of printed PA12 is described, starting with compounding, filament wire fabrication and finally, FDM printing. The potential to process PA12 using this technique and mechanical, thermal and morphological properties were also examined. Commonly, a reduction of mechanical properties of printed parts would occur in comparison with injection moulded parts despite using the same material. Therefore, the mechanical properties of the samples prepared by injection moulding were also measured and applied as a benchmark to examine the effect of different processing methods. The results indicated that the addition of fillers improved or maintained the strength and stiffness of neat PA12, at the expense of reduced toughness and flexibility. Melting behaviours of PA12 were virtually insensitive to the processing techniques and were dependent on additional fillers and the cooling rate. Incorporation of fillers slightly lowered the melting temperature, however improved the thermal stability. In summary, PA12 composites were found to perform well with FDM technique and enabling the production of medical implants with acceptable mechanical performances for non-load bearing applications.
