Assessment of Recycled PETG as a Support Material for PLA-Based 3D Printed Anatomical Models

Abstract

Three-dimensional (3D) printing technology provides the opportunity to reconstruct complex anatomical models with high accuracy. In the literature, it has been emphasized that the selection of support materials applied to three-dimensional models and the method of their removal after printing are decisive factors affecting both the production time and the integrity of the model. This study aimed to comparatively evaluate the effects of these two combinations on the printing process, support separation behavior and surface integrity by applying support structures from both the same material (PLA+PLA) and different material (PLA+recycled PETG) on model produced with polylactic acid (PLA) filament. In this study, five bone models (atlas, scapula, humerus, lumbar vertebrae, and ossa coxae) obtained from the same dog were produced in two different combinations to evaluate the compatibility of PLA and recycled PETG filaments: (1) PLA+PLA and (2) PLA+PETG. After printing, the support structures were manually removed, and comparative evaluations were performed in terms of surface deformation, ease of support removal, and printing time. Although the printing time was extended in the PLA+PETG combination due to filament transitions, it was observed that the supports were easily detached from the model surface, no surface deformation occurred, and the overall print quality was maintained. In contrast, in the PLA+PLA combination, detail loss and surface defects were detected during manual removal of the supports. As a result, it was concluded that the use of recycled PETG as a support material for the PLA main filament preserved the surface quality by reducing the risk of deformation on the model surface and could also be considered as an alternative support material.

PLA Temelli 3B Baskılı Anatomik Modellerde Destek Malzemesi Olarak Geri Dönüştürülmüş PETG’nin Değerlendirilmesi

Öz

Üç boyutlu (3B) baskı teknolojisi, karmaşık anatomik modelleri yüksek doğrulukla yeniden oluşturabilme olanağı sağlamaktadır. Literatürde 3B modellere uygulanan destek malzemesinin seçimi ve baskı sonrası uzaklaştırma yönteminin hem üretim süresi hem de model bütünlüğü üzerinde belirleyici olduğu vurgulanmaktadır. Bu çalışma ile polilaktik asit (PLA) filament ile üretilen ana modeller üzerinde hem aynı malzemeden (PLA+PLA) hem de farklı malzemeden (PLA+geri dönüştürülmüş PETG) destek yapıları uygulanarak bu iki kombinasyonun baskı süreci, destek ayrılma davranışı ve yüzey bütünlüğü üzerindeki etkileri karşılaştırmalı olarak değerlendirilmesi amaçlandı. Çalışmada, PLA ve geri dönüştürülmüş PETG filamentlerinin uyumluluğunu değerlendirmek amacıyla, aynı köpeğe ait beş kemik modeli (atlas, scapula, humerus, vertebrae lumbales ve ossa coxae) iki farklı kombinasyonda üretildi: (1) PLA+PLA ve (2) PLA+PETG. Baskı sonrası destek yapılar manuel olarak uzaklaştırılarak yüzey deformasyonu, destek kaldırma kolaylığı ve baskı süresi açısından karşılaştırmalı değerlendirme yapıldı. PLA+PETG kombinasyonunda filament geçişlerinden kaynaklı olarak baskı süresi uzasa da desteklerin model yüzeyinden kolaylıkla ayrıldığını, yüzey deformasyonu oluşmadığını ve genel baskı kalitesinin korunduğunu gözlendi. PLA+PLA kombinasyonunda ise desteklerin manuel kaldırılması sırasında detay kaybı ve yüzey bozulmaların olduğu belirlendi. Sonuç olarak, PLA ana filamentine destek malzemesi olarak geri dönüştürülmüş PETG kullanımı model yüzeyinde deformasyon riskini azaltarak yüzey kalitesini korumuş, aynı zamanda alternatif destek malzemesi olarak değerlendirilebileceği sonucuna varılmıştır.
