Pengaruh Setting Parameter pada Slicing Software terhadap Surface Roughness Objek 3D Printing menggunakan Metode Taguchi

Teknologi FDM (Fused Deposition Modelling) merupakan salah satu teknologi yang digunakan untuk membuat objek 3D. FDM sering disebut sebagai teknologi yang sudah mampu mengubah dunia manufaktur dewasa ini. Namun teknologi FDM memiliki kelemahan karena teknologi ini menggunakan proses building per layer membuat permukaan yang dihasilkan terlihat memiliki garis yang menunjukan batas antar layer sehingga mempengaruhi kekasaran pada permukaan produk cetak. Penelitian ini menggunakan filamen Super Tough PLA (ST.PLA). Tujuan penelitian ini adalah untuk mengetahui pengaruh parameter proses terhadap kekasaran permukaan objek cetak dan untuk mengetahui seting parameter proses yang menghasilkan kekasaran permukaan terbaik dari parameter proses yang digunakan. Penelitian ini menggunakan metode Taguchi dengan matriks ortogonal L25(56). Parameter proses yang akan dipilih dan dianalisis dalam penelitian ini adalah layer thickness, printing speed, nozzle temperature, orientation, flowrate, cooling speed dan respon yang diamati adalah kekasaran permukaan objek cetak. Untuk mengatasi permasalahan noise (gangguan) maka dicetak masing-masing tiga kali replikasi Selanjutnya parameter proses tersebut akan dianalisis menggunakan Analisis Varian (ANOVA). Berdasarkan data hasil pengukuran kekasaran permukaaan objek cetak, maka diperoleh parameter proses yang memberikan pengaruh paling besar terhadap kekasaran permukaan objek cetak dengan menggunakan filamen ST-PLA adalah layer thickness dengan nilai F hitung sebesar 129,96, flowrate dengan nilai F hitung sebesar 6 dan orientation dengan nilai F hitung sebesar 3,03. Seting parameter proses yang menghasilkan nilai kekasaran permukaan terbaik objek cetak adalah 0,10 mm yaitu pada eksperimen nomor lima (Exp. No. 5) dengan rata-rata 12,61 µm, dengan pengaturan layer thickness, 45 mm/s pada pengaturan printing speed, 210˚C pada nozzle temperature, 0˚ pada orientation, 110% pada pengaturan flowrate dan 40% pada pengaturan cooling speed.

The interest in producing cost-effective 3D printed metallic materials is increasing day by day. One of these methods, which has gained much attention recently, is the fused deposition modelling (FDM) method. The parameters used in the FDM method have significant effects on the printed part properties. In this study, CuSn10 bronze alloy was successfully produced. The printing speed and layer thickness were investigated as the printing process parameters, and their effect on morphological properties was characterized by using SEM. As a result, it was observed that the formation of printing-induced voids was prevented by applying a layer thickness of 0.2 mm. Additionally, by increasing printing speed, a slight decrease in product density was observed. Following determination of 3D printing parameters which give the highest printed part density, the parts were debound in hexane solution via solvent debinding. Finally, the parts were sintered at 850, 875 and 900 °C for 5 h to examine effect of sintering temperature on density, porosity, shape deformation and mechanical properties. Although partial slumping started to form over 875 °C, the highest density (94.19% of theoretical density) and strength (212 ± 17.72 MPa) were obtained by using 900 °C as the sintering temperature.

In the fields of agriculture, medical treatment, food, and packaging, polymers are required to have the characteristics of self-cleaning, anti-icing, and anti-corrosion. The traditional preparation method of hydrophobic coatings is costly and the process is complex, which has special requirements on the surface of the part. In this study, fused deposition modeling (FDM) 3D printing technology with design and processing flexibility was applied to the preparation of hydrophobic coatings on polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) parts, and the relationship between the printing process parameters and the surface roughness and wettability of the printed test parts was discussed. The experimental results show that the layer thickness and filling method have a significant effect on the surface roughness of the 3D-printed parts, while the printing speed has no effect on the surface roughness. The orthogonal experiment analysis method was used to perform the wettability experiment analysis, and the optimal preparation process parameters were found to be a layer thickness of 0.25 mm, the Grid filling method, and a printing speed of 150 mm/s.

Experimental design has been used to determine outlying factors that affect tensile strength of fused deposition modelling 3D printed PLA parts. A two level, three factor full factorial experiments were utilized to determine the best combination of factors that yielded the highest tensile strength of PLA tensile dog bones manufactured in accordance with ASTM D638-14. PLA is particularly desirable due to its environmental friendliness, biodegradability, low cost, and low melting point, allowing it to be built on a non-heated platform without risk of toxic fumes. Increasing the tensile strength of PLA will allow PLA to be used in a wider range of applications that demand stronger plastic parts. The chosen factors were infill percentage, nozzle temperature, and printing speed. The tensile strength was affected by all factors and combinations except for high levels of infill percentage, nozzle temperature, and printing speed combined.

Three-dimensional printing or 3D printing (also called additive manufacturing) is any of various processes used to make a three-dimensional object. Fused deposition modelling (FDM) is an additive manufacturing technology commonly used for modelling, prototyping, and production applications. It is one of the techniques used for 3D printing. FDM is somewhat restricted in the size and the variation of shapes that may be fabricated. For parts too large to fit on a single build, for faster job builds with less support material, or for parts with finer features, sectioning and bonding FDM parts is a great solution. The strength of adhesive bonded FDM parts is affected by the surface roughness. In this study, the layer thickness effect on bonding strength is experimentally studied and the results are discussed.
