Investigations of The Relative Strength of Lattice Infilled Parts Manufactured by Fused Deposition Modelling
Abstract
Fused deposition modeling (FDM), one of the most common methods of additive manufacturing, has been widely used in recent years. It is generally preferred in applications for products where high mechanical properties are not required and where visuality is at the forefront instead of functionality. However, as a result of the enrichment of new materials developed for the FDM method with elastomers and composites, different application areas have emerged. This study focuses on the mechanical properties of elastomeric TPU and carbon fiber-reinforced TPU materials in addition to the traditionally used PLA filaments. The compressive strength and relative strength values resulting from the use of different processing strategies and lattice structures were investigated. Thus, lightweight, low-cost, and high-relative strength structures that can be produced in a shorter time with lattice structures and processing strategies have been obtained. Furthermore, compression tests revealed that TPU and carbon fiber-reinforced TPU materials, in particular, returned to their initial geometry with spring back.

Abstract
Geniş kullanım alanına sahip Eklemeli İmalat yöntemlerinden Eriyik Yığma Modellemenin (EYM) tercih edilirliği gittikçe artmaktadır. Genellikle, yüksek mekanik özelliklere ihtiyaç duyulmayan, fonksiyonellik yerine kozmetik unsurların ön planda olduğu ürünlere yönelik uygulamalarda tercih edilmektedir. EYM yöntemi için geliştirilen yeni malzemelerin, elastomer ve kompozitlerle zenginleşmesi sonucunda farklı uygulama alanları da karşımıza çıkmaya başlamıştır. Bu çalışma kapsamında, standart PLA filamentlerin yanı sıra, elastomer özellikteki TPU ve kompozit yapıdaki karbon elyaf takviyeli TPU malzemelerin mekanik özelliklerine odaklanılmıştır. Farklı üretim stratejileri ve kafes yapıların kullanılması sonucunda elde edilen ürünlerin basma dayanımı ve bağıl mukavemeti araştırılmıştır. Böylece kafes yapılar ve imalat stratejileri ile düşük maliyetli ve bağıl mukavemeti yüksek yapılar daha kısa imalat sürelerinde elde edilebilmiştir. Ayrıca, özellikle TPU ve karbon elyaf katkılı TPU malzemelerin basma testleri sonucunda geri yaylanma “spring back” ile başlangıç geometrisine dönme davranışı sergilediği tespit edilmiştir.
