Tensile tests of specimens made of selected group of the filament materials manufactured with FDM method

Abstract

Abstract. This paper presents results of tensile tests carried out for specimens made of the selected group of the filament materials. As a manufacturing technology FDM 3D printing method was chosen. The selected group of the filament materials involved the group of wood, PLA, ABS, PET, PMMA and ASA. Herein, it should be noticed, that technical data sheets that are delivered by filament materials producers include data that are valid for only one specific printing direction. This printing direction is deliberately selected, in such way that ensures the best material characteristics. Therefore, received during the research results allow to make comparison between a catalogue data and data obtained in the printing process. It aids both mechanical designer and product manufacturer at the stage of the printed product mechanical properties shaping. The selection of the materials subjected to the tensile testCurrently, a vast variety of materials is available on the market. This group of materials is called filament. Filament is a thermoplastic material. It is wound on the spool in the form of a thin wire. Typically, the spool contains 1 kg of a material. In our case, 1.75 mm diameter filament was used. Manufacturers of the filament are constantly trying to surprise clients with new materials. A few years ago, only ABS or PLA were in the offer. Nowadays, these materials are the basis of FDM technology and they are the most popular. Newer and newer materials are commercially available. For example, materials with admixtures of wood or chalk, which were created for design applications. On the other hand, the impact of the industry has demonstrated a need for materials for engineering applications, such as ABS, ASA, Nylon, PET, PMMA or rubber. Above the basic properties of the selected materials are given.3DGO Wood is a product name of the material made by 3DFilamenty Company. The original name of this filament is LayWoo-D3 or LayWood and it was created by Kai Parthy from CC-Products Company [1]. This filament consists of 60% of PLA which is the base of this filament and 40% of wooden powder which is an admixture. The material has a wood *

Comparison of Mechanical Properties of PLA and ABS Based Structures Produced by Fused Deposition Modelling Additive Manufacturing

“…According to the results obtained, the tensile strengths are 62 MPa, 35 MPa, 29 MPa and 55 MPa, respectively (Svensson, 2017). Grabowik et al (2017) analyzed wood, PLA, ABS, PET, PMMA and ASA filament material group and material properties with tensile tests using FDM additive manufacturing method. In the results of tensile strength for PLA materials, the value of the peak stress is between 38 and 38.4 MPa.…”

“…The value of the strain at peak stress is between 5.5 and 5.6%. The value of the Young's modulus is between 856 and 864 MPa (Grabowik et al, 2017). While the tensile test results (66.5 MPa) for horizontal, (49.5 MPa) for flat, (26.1 MPa) for vertical values are obtained, the bending test results are (98.6 MPa) for horizontal, (93.5 MPa) MPa) for straight and (42.3 MPa) vertical values were obtained (Caminero et al, 2019).…”

Increasing of Strength of FDM (FFF) 3D Printed Parts by Influencing on Temperature-Related Parameters<strong> </strong>of the Process

“…That fact allows researchers to enjoy a certain freedom in choosing the geometry of the test sample and the way to apply load to it. However, most of the known works [8][9][10][11][12][13][14][15] on the dependence of FDM (FFF) parts strength on certain parameters are based on the techniques described by the standard [16], developed for testing isotropic materials. In our opinion, a simple and informative technique for evaluating the strength of a part obtained with FDM (FFF) is a three-point bending until the sample is broken [17].…”

Peningkatan Kekuatan Lentur Produk 3d Printing Berbahan Petg Dengan Optimasi Parameter Proses Menggunakan Metode Taguchi

“…Beberapa filamen yang sering digunakan pada 3D printing diantaranya adalah polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), nylon, polyethylene terephthalate glycol (PETG) dan polycarbonat (PC). PETG merupakan salah satu jenis polimer yang memiliki densitas 1,38 g/cm 3 dan mempunyai banyak keunggulan, antara lain ketahanan terhadap kondisi cuaca, tidak rusak atau kehilangan warnanya saat terkena sinar UV, tidak menimbulkan bau saat proses pencetakan, memiliki sifat adhesif yang unik sehingga mampu menempel di meja pemanas dengan baik, dan memiliki faktor penyusutan termal yang rendah [3]. Polimer ini sering digunakan dalam pembuatan produk 3D Printing menggunakan suhu pencetakan 230°C-265°C dan suhu bed di atas 60˚C.…”
