OPTIMASI PARAMETER PROSES 3D PRINTING TERHADAP AKURASI DIMENSI DAN TRANSPARANSI FILAMEN PETG MENGGUNAKAN METODE GREY TAGUCHI

3D printing technology is very widely used, especially in the industrial sector.
In the 3D printing process, prototyping can be made in a short time. Fused Depositon
Modeling (FDM) technology is a technique used to print products using materials
and products that have ideal geometric characteristics. Based on the research that
has been done, the authors conducted research on 3D Printing using PETG
(Polyethylene Terephthalate Glycol) filament types with process parameters namely
print temperature (240°C), (245°C), (250°C), build plate temperature (85 °C),
(90°C), (95°C), print speed (50 mm/s), (55 mm/), (60 mm/s), fan speed (30 mm/s), (40
mm /s), (50 mm/s ) and layer height (0.15 mm), (0.20 mm), (0.25 mm). With the
Taguchi L27(35
) method for printing products using parameters and 5 variations in
response to dimensional accuracy and transparency. This study aims to determine the
dimensional accuracy and transparency of 3D printing product materials with PETG
(Polyethylene Terephthalate Glycol) filaments with different parameters using the
Gray Taguchi Method and to find out how much they affect printing using PETG
(Polyethylene Terephthalate Glycol) filaments with 5 process parameters tested are:
print temperature, build plate temperature, print speed, fan speed, layer height, and
with three levels that affect the testing of dimensional accuracy and transparency.
Based on the experiments conducted in this study, it can be conclude that the highest
dimensional accuracy is printed specimens with the parameter values print
temperature (xxx), build plate temperature (xxx), print speed (xxx), overlap (xxx), and
layer heights (xxx). Meanwhile the highest level of transparency is the printed
specimens with the parameter values print temperature (xxx), build plate temperature
(xxx), print speed (xxx), overlap (xxx), and layer heights (xxx).
