Son
yıllarda 3B baskı teknolojileri sahip olduğu yüksek üretim hızı, uygun maliyeti
ve biyouyumlu malzeme üretimine imkan veren özellikleriyle yapay organ
geliştirme alanına önemli yenilikler getirmiştir. Bu çalışmada, eriyik yığma
modellemesi (EYM) özelliğine sahip bir 3B yazıcı kullanarak poliüretan (PU)
polimeriyle hacimsel olarak farklı doluluk oranlarında (%25, %50, %75 ve %100)
yapay insan kulak kepçesi üretimi gerçekleştirilmiştir. Kimyasal yapı
analizleri için Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi, termal
analizler için termogravimetrik analiz (TGA) cihazı, yüzey görüntülerini
incelemek için stereomikroskop ve taramalı elektron mikroskobu (SEM), mekanik
ölçümler için sertlik ve çekme testi cihazları kullanılmıştır. Geliştirilen
yapay kulak kepçelerinden en uygun tasarımın %50 doluluk oranına sahip olan
kulak tasarımı olduğu belirlenmiştir.

Production of an Artificial Human Auricle from Polyurethane by Using Three Dimensional (3D) Additive Manufacturing Technique Based Fused Deposition Modelling

Öz

In
recent years, 3D printing technologies have brought significant innovations in
the field of artificial organ development due to their properties such as high
production speed, cost effective and enabling fabrication of biocompatible
materials. In this study, artificial human auricles were produced in different
infill rates (25%, 50%, 75% and 100%) volumetrically with polyurethane (PU)
polymer by using a 3D printer based on fused deposition modelling (FDM).
Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analyzer
(TGA), stereomicroscope, scanning electron microscope (SEM), hardness tester
and tensile test machine were used for chemical structure analysis, thermal
analysis, surface images and mechanical measurements respectively. It was
determined that the most suitable design among the developed artificial
auricles is the auricle having 50% infill rate.
