Abstract
Proses ekstrusi filamen 3D-Print memiliki berbagai tantangan dalam upaya menghasilkan filamen 3D-Print yang berkualitas. Salah satu faktor penting dalam mempertimbangkan kualitasnya yakni memiliki diameter dengan toleransi ±0,05mm. Untuk dapat menghasilkan filamen dengan toleransi tersebut, dibutuhkan konsistensi proses ekstrusi yang baik. Komponen mesin ekstrusi yang paling berpengaruh terhadap proses ini adalah bagian screw. Sehingga sangat penting untuk melakukan modifikasi desain komponen screw dengan baik pada mesin ekstrusi filamen. Pada penelitian ini, dilakukan modifikasi desain screw pada mesin ekstrusi filamen di CV. Robries Indonesia untuk mengatasi fluktuasi diameter filamen. Material polimer yang digunakan pada proses produksi filamen ini adalah polipropilena (PP). Pada penelitian ini, mula-mula dilakukan pengamatan terhadap temperatur dan arus listrik motor penggerak pada proses produksi filamen untuk mengetahui fluktuasi sistemik akibat fenomena surging. Selanjutnya untuk mengatasi fluktuasi filamen akibat ketidaksempurnaan proses mixing dilakukan modifikasi desain screw dengan melakukan penambahan Maddock mixer pada komponen screw. Variasi dilakukan terhadap desain Maddock mixer yang digunakan dengan mengubah kedalaman undercut pada Maddock mixer. Pengamatan terhadap diameter filamen dilakukan melalui pengukuran secara langsung dengan jangka sorong dan pengamatan secara makro. Melalui penelitian ini diketahui bahwa penambahan Maddock mixer pada screw tidak mengakibatkan perbaikan pada kualitas diameter filamen yang dihasilkan. Sementara itu, variasi terhadap kedalaman undercut pada Maddock mixer mempengaruhi temperatur ekstrusi dan kecepatan/laju ekstrusi.

There are many challenge to produce a good 3D-Print filament. One of the main criterion of a good 3D-print filament is having a diameter tolerance up to ±0,05mm. A good and consistent extrusion process needed to produce 3D-Print filament with that tolerance. The most influential component of the extrusion machine for this process is the extrusion screw. So it is very important to do design evaluation to the screw component in the filament extrusion machine. In this study, screw design modification on filament extrusion machines was carried out on the CV. Robries Indonesia. Screw design is intended to overcome fluctuations in filament diameter. Polymer material used in the production process of this filament is polypropylene (PP). In this study, the temperature and electric current of the driving motor were first observed in the filament production process to determine systemic fluctuations due to the phenomenon of surging. Furthermore, to overcome filament fluctuations due to imperfections in the mixing process, modification of screw design was carried out by adding Maddock mixers to screw components. Variations made on the design of the Maddock mixer are used by changing the undercut depth in the Maddock mixer. Observation of the filament diameter was carried out through direct measurement with a vernier caliper and macro observation. Through this research it is known that the addition of Maddock mixer to the screw does not result in an improvement in the quality of the diameter of the filament produced. Meanwhile, variations in the undercut depth on Maddock mixer affect the extrusion temperature and extrusion speed rate.
