Abstract

The usage area of 3D printers from architecture to heavy industry has been increasing in recent decades. By this process, it is possible to manufacture structures having different geometric configurations to improve the mechanical, vibration, impact, and acoustic properties of the structures. In this study, three-point test specimens with different topologies were produced by the 3D printing method in order to see the effect of the geometric configuration. The specimens having 100% infill density were produced using PLA (Polylactic Acid), ABS (Acrylonitrile Butadiene Styrene) and PETG (Polyethylene terephthalate glycol-modified) filament materials with the additive manufacturing method, which is the most widely used method in three-dimensional production. Numerical and experimental results are compared for loading conditions at specific force values.

Topoloji ve Malzemenin Eklemeli İmalat Yöntemiyle Üretilen Yapıların Mekanik Özelliklerine Etkileri

Abstract

Son yıllarda mimariden ağır sektöre kadar 3B yazıcıların kullanım alanı artmaktadır. Bu yöntem ile yapıların mekanik, titreşim, darbe ve akustik özelliklerini iyileştirmek için farklı geometrik konfigürasyonlara sahip yapılar üretmek mümkündür. Bu çalışmada, geometrik konfigürasyonun etkisini görmek için farklı topolojilerde üç nokta deney numuneleri 3B baskı yöntemi ile üretilmiştir. % 100 dolgu yoğunluğuna sahip numuneler PLA (Polilaktik asit), ABS (Akrilonitril bütadien stiren) ve PETG (polietilen tereftalat glikolle değişmiş) filament malzemeleri kullanılarak üç boyutlu üretimde en yaygın kullanılan yöntem olan eklemeli imalat yöntemi ile üretilmiştir. Belirli kuvvet değerlerindeki yükleme koşulları için sayısal ve deneysel sonuçlar karşılaştırılmıştır.
