Fused Deposition Modeling (FDM) is a 3D Printing technique used to print products using filaments as material. The printed product has ideal geometric characteristics if it has meticulous size and perfect shape. One type of material that can be processed using 3D Printing FDM is flexible material. Research in terms of dimensional accuracy has been carried out on PLA and ABS materials. While research using flexible materials is still rarely done. From these problems, we need a study to get the process parameter settings on a 3D Printer machine that is optimal in obtaining dimensional accuracy using flexible materials. The research was carried out using the Prusa model DIY (Do It Yourself) 3D machine with FDM technology. The material used is Eflex type flexible filament with a diameter of 1.75 mm. The process parameters used in this study are flowrate, layer thickness, temperature nozzle, speed printing, overlap, and fan speed. Cuboid test specimens measuring 20 mm × 20 mm × 20 mm. Process parameter optimization using the Taguchi L27 Orthogonal Array method for dimensional accuracy testing. Optimal process parameter values for obtaining X dimension accuracy are 110% flowrate, 0.10 mm layer thickness, 210 °C nozzle temperature, 40 mm/s print speed, 75% overlap, and 50% fan speed. Y dimension is 120% flowrate, layer thickness 0.20 mm, nozzle temperature 230 °C, print speed 30 mm/s, overlap 75%, and fan speed 100%. As well as the Z dimension is 120% flowrate, layer thickness 0.30 mm, nozzle temperature 210 °C, print speed 30 mm/s, overlap 50%, and fan speed 100%.
3D printing technology is one of the new breakthroughs in the world of manufacturing. This principle uses layered modeling, which directly converts 3D data from computer-aided design (CAD) into physical prototypes. Additive Manufacturing technology itself has attracted a lot of interest as research material from industry to academia because it can provide manufacturing solutions that produce products with complex designs and reduce time without compromising print quality. Currently, the Fused Deposition Modeling (FDM) process is the most widely used process in 3D printing due to its ease of operation, low operating costs and environmental convenience. This study uses the Taguchi method with quality characteristics the bigger the better. The experimental design used is L27 OA by analyzing the Signal to Noise Ratio SNR. The method is based on the principle of tensile strength, to determine the process parameters that greatly affect the ABS CCTREE filament. The process parameters used in this research are nozzle temperature, layer thickness, temperature based plate, print speed and infill pattern. The order of the most influential parameters in a row is layer thickness of 40,74%, print speed of 9,40%, nozzle temperature of 5,69%, temperature based plate of 5,56% and infill pattern of 4,36%.
Rice is one of the basic foodstuffs consumed by the people of Indonesia as well as Bangka Belitung Islands Province more precisely Bangka Regency Riau Silip Village Banyu Asin. Freshly harvested rice is usually still not separated from straw / malai. The process of harvesting rice still uses traditional tools or also called gebotan. The threshing machine available in Banyu Asin has not been able to maximize the results of the platform, which resulted in the length of the threshing process. Based on these needs, it was designed to build a rice threshing machine to facilitate the threshing process. Rice threshing machine design refers to the VDI 2222 method of development which has 4 (four) stages, namely: planning, conceptualizing, designing, and finishing, then assessed based on technical, and economic aspects. The conclusion obtained during the design process of the rice threshing machine is the design of the machine weighing 60 kg lighter than the existing machine is easy to move and the design of the machine whose components are easy to remove installs. The design of a rice threshing machine that is able to knock rice as much as 86.4kg / hour, compared to existing machines is only able to knock rice as much as 30kg / hour.
<p>Pengaturan parameter proses 3D <em>Printing </em>berteknologi <em>Fused Deposition Modelling</em> (FDM) sangat mempengaruhi kualitas produk cetak baik dalam hal akurasi dimensi, <em>surface roughness</em>, dan kekuatan tariknya. Dua material yang paling sering digunakan para praktisi 3D Printing adalah PLA dan ABS masih memerlukan pengaturan parameter proses pada <em>slicing software</em> untuk menghasilkan produk cetak paling kuat ditinjau dari kuat tariknya. Penelitian ini memvariasikan bentuk geometri <em>infill </em>yang tersedia pada Ultimaker Cura 4.8.0 dalam mencetak spesimen uji tarik ASTM D638 Type IV. Ada 13 (tiga belas) bentuk <em>infill </em>yang digunakan dengan <em>infill density</em> 100%. Ada 3 (tiga) variasi <em>nozzle temperature</em> yaitu 205°C, 215°C, dan 225°C. Parameter proses yang tetap seperti <em>layer thickness</em> 0,2 mm, <em>printing speed</em> 50 mm/s, <em>travel speed</em> 100 mm/s, dan <em>bed temperature</em> 60°C. Spesimen uji tarik dicetak masing-masing tiga buah pada 39 (tiga puluh sembilan) eksperimen dan rata-rata hasil uji tarik dihitung kemudian selanjutnya dianalisis. Nilai kekuatan tarik tertinggi diperoleh pada pengaturan <em>nozzle temperature</em> 205°C dengan bentuk <em>infill concentric</em> atau terdapat pada eksperimen nomor 9 dengan nilai 32,40 MPa. Sedangkan nilai kekuatan tarik diperoleh pada pengaturan <em>nozzle temperature</em> 225°C dan dengan bentuk <em>infill cross</em> atau pada eksperimen nomor 37 dengan nilai 19,10 MPa. Sehingga dapat disimpulkan bahwa bentuk geometri <em>infill </em>pada proses 3D <em>Printing </em>FDM sangat mempengaruhi kekuatan tarik produk cetak.</p>
