Abstract

Son yıllarda, eklemeli imalat sektörü
ve teknolojisinin ilgisine ve önemine paralel olarak, üç boyutlu (3B) parça
üretimi için kullanılan fotokürlenebilir polimer reçineler üzerine yapılan
çalışmalar büyük ilgi görmektedir. Eklemeli imalat yöntemlerinden biri olan
Streolitografi (SLA) yöntemi, yüksek hızlı işleme ve parça üretimi hassasiyeti
açısından diğer yöntemlerden ayrılmasının yanı sıra mekanik ve diğer
karakteristik özelliklerinin değiştirilmesine izin vermektedir. Özellikle
polimer kompozit malzemelerin mekanik dayanımını arttırmak için birçok çalışma
günümüze kadar yapılmaktadır. Kil, Al₂O₃, SiO₂,
BaTiO₃, ZrO₂ gibi seramik malzemeler mekanik dayanımı
artırmak için takviye malzemesi olarak örnek verilebilir.  Bu çalışmada, dört farklı (katkısız, %0,25,
%0,5, %1) konsantrasyona sahip füme silika katkılı polyester esaslı akrilat
fotokürlenebilir reçinenin mekanik özelliklerine etkisi araştırılmıştır. 167m²/gr
yüzey alanına sahip füme silika %0,25, %0,5 ve %1 konsantrasyonlarında
fotokürlenebilir reçineye eklenmiştir. Çekme testi, dinamik mekanik analiz
(DMA) ve taramalı elektron mikroskobu (SEM) sonuçlarına göre, SLA
kompozitlerinin artan füme silika konsantrasyonu ile birlikte mekanik
dayanımının artmasına rağmen termal kararlılığında azalma  (depolama ve kayıp modülü) görülmüştür. Füme
silikanın yüksek yüzey alanı nedeniyle, fotokürlenebilir reçine içerisinde %1
konsantrasyonuna kadar nispeten daha iyi homojen dağıldığı olduğu
gözlemlenmiştir.

Investigation of Mechanical Properties 3D Printable Fumed Silica Added Photo-Curable Polymers

Abstract

In recent years, parallel to the interest and
importance of additive manufacturing sector and technology, the studies on photo-curable polymer resins which will be used fort
he production of 3-D parts have attracted great interest in recent years.
Streolithography (SLA) method, which is one of the additive manufacturing
methods, is distinguished from other methods in terms of high
speed machining and part production precision. Moreover, it allows for the
production of functional polymeric structures by enhancing their mechanical,
thermal, electrical properties, etc… In particular, it has been known that
studies to increase the mechanical strength of polymer composite materials are
very common. Ceramic materials such as clay, Al₂O₃, SiO₂,
BaTiO₃, ZrO₂, etc are used as reinforcing materials for mechanical
strength. In this study, the improvement of mechanical properties of polyester
based acrylate photo-curable resin by reinforcement with fumed silica fillers
were investigated. Fumed silica with 167m²/gr surface was added into
photo-curable resin at three different (%0,25, %0,5 and %1) concentration.
According to the tensile test, dynamic mechanical analyzer (DMA) and scanning
electron microscope (SEM) observation, even though mechanical properties
enhances, thermal stability (storage and loss modulus) values of SLA composites
are decreased as increasing amount of fumed silica. Due to its high surface
area of reinforcement agent, it is clearly seen that fumed silica completely
dispersed in the photo-curable resin up to %1 fumed silica concenration.
