“…Three-dimensional printing is divided into four main manufacturing methods: stereolithography (SLA), laminated object manufacturing (LOM), selective laser melting (SLM) and fused deposition modeling (FDM) (Hull, 1986;Chua et al, 2003;Crump, 1989;Novakova-Marcincinova and Novak-Marcincin, 2013).…”

“…A design of experiments (DOE) testing protocol will evaluate test samples as done previously by Ahn et al (2002) to evaluate FDM printing of ABS samples material properties. The DOE method for evaluating FDM-printed parts has been investigated using commercial 3D printers (Ahn et al, 2002;Sood et al, 2010;Novakova-Marcincinova and Novak-Marcincin, 2013), but this method has not been performed on Desktop 3D printers. Three variables that are readily manipulated using MakerBot 's print software were identified (layer height, print orientation and infill percentage) and will be the subject of our DOE strength and elastic modulus study.…”

Purpose – This paper aims to evaluate the material properties and dimensional accuracy of a MakerBot Replicator 2 desktop 3D printer. Design/methodology/approach – A design of experiments (DOE) test protocol was applied to determine the effect of the following variables on the material properties of 3D printed part: layer height, per cent infill and print orientation using a MakerBot Replicator 2 printer. Classical laminate plate theory was used to compare results from the DOE experiments with theoretically predicted elastic moduli for the tensile samples. Dimensional accuracy of test samples was also investigated. Findings – DOE results suggest that per cent infill has a significant effect on the longitudinal elastic modulus and ultimate strength of the test specimens, whereas print orientation and layer thickness fail to achieve significance. Dimensional analysis of test specimens shows that the test specimen varied significantly (p < 0.05) from the nominal print dimensions. Practical implications – Although desktop 3D printers are an attractive manufacturing option to quickly produce functional components, this study suggests that users must be aware of this manufacturing process’ inherent limitations, especially for components requiring high geometric tolerance or specific material properties. Therefore, higher quality 3D printers and more detailed investigation into the MakerBot MakerWare printing settings are recommended if consistent material properties or geometries are required. Originality/value – Three-dimensional (3D) printing is a rapidly expanding manufacturing method. Initially, 3D printing was used for prototyping, but now this method is being used to create functional final products. In recent years, desktop 3D printers have become commercially available to academics and hobbyists as a means of rapid component manufacturing. Although these desktop printers are able to facilitate reduced manufacturing times, material costs and labor costs, relatively little literature exists to quantify the physical properties of the printed material as well as the dimensional consistency of the printing processes.

“…The main advantage of RP technology methods is not only the possibility of fast production in any phase of product development, but mainly the possibility of manufacturing a wide range of modifications and configurations of the proposed product. The modern RP technology is receiving increased attention, thanks in significant technical and economic benefits in the development of new products, prototypes or samples [2][3][4][5][6][7][8][9][10][11].…”

The article is focused on the aspects in samples production of sophisticated material – PLA - PolyLacticAcid, PLA plastic. The main part of the work focuses on experimental production and testing of PLA material - PolyLacticAcid plastic, printed on RepRap 3D device that works on the "open source" principle. The article presents the outcomes of test materials in the form of measurement protocols recorded in the software, the measured values in a static tensile test, marked down in tables and shown in work graphs. The article describes selected and carried out tests of mechanical properties of PLA plastics extruded in different directions in this case carried out vertically by FDM rapid prototyping method of two PLA materials such as pure without additives blended with blue dye. The tests are mainly focused on the determination of ultimate tensile strength. Based on the results obtained, the samples made of two PLA materials were compared in the end to establish which produced PLA material sample is stronger. There are outputs in the form of logs, charts and tables that provide information about the executed tests and comparisons, which were made by the authors.

“…The computer model adequately oriented, performs slicing (cut into thin layers) and automatically generates data. His output STL format, which includes geometric data of the individual layers can then be transferred directly to the FDM modeling device [2][3][4][5][6][7][8][9][10][11][12].…”
