Abstract

FDM (Fused Deposition Modeling) is one of the methods often usen by researchers in 3D printing technology which is used to print filaments products as a materials, due to the easy technique for 3D printing with relatively low production costs. One of the materials that can be processed in a 3D printing machine ia PLA+. Research in tensile testing has been done on PLA and ABS filaments. Meanwhile, tensile testing using PLA+ filaments is still rarely done. From these problems, research is needed to get the optimal process parameters on the 3D printing machine to get the highest tensile strenght value using PLA+ filaments. This research uses the taguchi method, carried out on a PRUSA area model FDM 3D Printing machine with dimensions of 300mm x 300mm x 350mm using a nozzle size of 0.4mm. The material used is PLA + Esun filament with a diameter of 1.75 mm with a variety of printing speed parameters (30 mm/s, 35 mm/s, 40 mm/s, 45 mm/s, 50 mm/s), nozzle temperature (1950C, 2000C, 2050C, 2100C, 2150C), layer thickness (0.10mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm), cooling speed (20%, 40%, 60%, 80%, 100%), orientation (00, 300, 450, 600,900) which will be determined in ideamaker 3.6.1 to produce 75 printed samples. This research aims to determine the optimal tensile strength value. From the research results there is an optimal tensile strength value, namely in experiment 10 with the parameter values of printing speed (35 mm/s), Nozzle Tenperature (2150C), Layer Thickness (0.10mm), Cooling speed (20%), and Orientation (450). with a tensile strength value of 48.1 MPa from 3 replications.

Abstract

Fused Deposition Modeling (FDM) is a technique of 3D Printing machines that is popularly used to print products. The printed product certainly has the ideal tensile strength characteristics if it has a precise size and good shape according to the standard. One of the materials that can be processed in a 3D printing machine is ST PLA. Research in terms of tensile testing has been carried out on PLA/ABS materials. However, tensile testing with annealing process using ST PLA filament is still very rarely done. From these problems, it is necessary to research to obtain optimal process parameters on 3D printing machines, to obtain the highest tensile strength from the annealing process using ST PLA material. This research was conducted using a 3D printer DIY Prusa model with a printing area of ​​XYZ, 300 mm x 300 mm x 350 mm. The material used is ST PLA filament with a diameter of 1.75 mm in green. The process parameters in this research are layer thickness, nozzle temperature and flow rate. For annealing media use beach sand, coffee and wheat. The shape of the test specimen follows the ASTM D638 type IV standard. As for the design of the process parameters using the Taguchi L9 method (33). The process parameter values ​​that produce the highest tensile strength without annealing are layer thickness 0.3 mm, nozzle temperature 205oC, and flow rate 100%. The annealing process parameters that produce the highest tensile strength are annealing time of 15 minutes, oven temperature of 110oC, for annealing media using coffee.
