Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh variasi fraksi volume struktur kisi 3D printing terhadap tegangan dan elastitstas dengan menggunakan metode numerik. Beberapa struktur kisi yang akan dievaluasi yaitu SchwarzD, SchwarzP, ScheonIWP, dan Nevious. Model CAD dari struktur kisi akan dihasilkan dengan menggunakan script berbasis Python. Variasi fraksi volume dihasilkan dengan cara memvariasikan nilai ketebalan shell struktur kisi pada script Python. Analisis dilakukan dengan menggunakan metode numerik berbasis metode elemen hingga dengan analisis statis dan model material elastis. Material yang digunakan adalah material ABS. Berdasarkan hasil penelitian, hubungan ketebalan script dan fraksi volume menunjukan bahwa setiap sturktur kisi akan menghasilkan fraksi volume yang berbeda satu sama lain. Hal ini dapat terlihat ketika memvariasikan nilai ketebalan shell. Semakin besar nilai ketebalan shell maka nilai fraksi volume struktur kisi akan semakin besar. Setiap struktur memberikan respon tegangan yang berbeda, dan setiap tegangan memliki daerah titik konsentrasi tegangan yang berbeda. Setiap struktur kisi memiliki sifat dan prilaku yang unik yang hubunganya tidak selalu linier terhadap fraksi volume. Secara umum, berdasarkan data tersebut, urutan struktur kisi yang memiliki nilai tegangan dan modulus elastisitas paling tinggi hingga yang rendah adalah struktur 3D printing SchwarzD, Nevious, ScheonIWP, dan SchwarzP
