Abstract

Penelitian tentang produk cetak dengan menggunakan 3D Printing berteknologi Fused DepositionModelling (FDM) telah banyak dilakukan oleh para peneliti. Salah satunya adalah penelitian tentang kekuatan lentur atau flexural strength dengan menggunakan standar ASTM D790, baik dengan filamen ABS, PLA, Nylon, maupun material maju lainnya seperti komposit. Penelitian ini menggunakan filamen Super Tough PLA dengan setting parameter proses pada slicing software dan menggunakan mesin 3D Printer Anycubic 4Max dengan nozzle diameter 0,4mm, layer thickness 0,28mm, Top solid Layer 1, Bottom Solid Layer 1, Vertical shell 1, Fill density 100%, printing speed 60 mm/s, bed temperature 60 °C, cooling speed 100%, dan flowrate 100%, Spesimen uji Standar ASTM D790 diaplikasikan pada penelitian ini. Penelitian ini hanya memvariasikan bentuk infill pattern. Sebanyak dua belas variasi infill pattern yang digunakan pada penelitian ini. Penelitian ini telah menghasilkan kekuatan lentur specimen uji ASTM D790 dengan perbedaan sebesar 59,17%. Kekuatan lentur dengan nilai terendah rata-rata sebesar 27,10MPa, dan nilai kekuatan lentur tertinggi rata-rata sebesar 45,80MPa.

Abstract

Bone joint plates have a high production potential. This can be seen from the number of cases related to trauma to the bone which has increased quite high in Indonesia. The jaw bone joint plate or commonly known as the mini plate serves to connect the bones in the jaw that has been traumatized or broken. The manufacture of mini plates generally uses an EDM machine, wire cutting and laser cutting which can only process with a gradual working principle. Based on the description above, it is necessary to manufacture a micro punch machine for the manufacture of jaw bone joint plates (mini plates), so that they can be used to mass produce mini plates. This study aims to design a mini punch machine for the manufacture of a mini plate using a research method that refers to the book Product Design and Development (Karl T. Ulrich, Steven D. Eppinger) in order to obtain an optimal machine design. The results obtained based on the research method used, obtained a micro punch machine design for the manufacture of a mini plate using the working principle of a progressive tool, a pneumatic prime mover and a material strip drive using a fedder system.
