OPTIMASI AKURASI DIMENSI PROSES 3D PRINTING DENGAN FILAMENT PLA+ MENGGUNAKAN METODE TAGUCHI

3D printing is an improvement of printing technology that proves that there are major changes in the world, especially in the field of manufakur. Where Filament is chosen, PLA+ because it has a higher level of toughness, is stronger, stiff and provides better adhesion, toughness, and layer surface quality. And also uses the Taguchi L9 method because it is a quality improvement effort that focuses on improving product design and processes in order to obtain dimensional accuracy results with several parameter variations such as Nozzle Temperature 210,215,2200C, Print Speed 70,75,80mm/s, Wall Thickness 0,2,0,25,0,3mm. Measurements were made using a digital caliper to obtain a size value from the manufacture of specimens where the specimen size was 20mm on the same side. where specimen 6 has the closest or best dimensional accuracy, which is 20.05 mm with a difference from the size of the test specimen of 20 mm, which is 0.05 mm.
