Abstract:

 Polymer materials are widely used in various fields of the world economy and their properties are developing rapidly. The emergence of new technologies such as additive manufacturing AM has created needs such as higher performance and functionality for polymer materials and composites. Polymer powder materials are one of the most used consumables in EI technologies and are mainly used in selective laser sintering SLS technology. SLS is a powder bed fusion process that produces 3D solid components by selectively sintering successive layers of powder raw materials according to a 3D 3D computer aided design model. In this study, Polyamide 12 PA12 pellets were pulverized by fiber melting method and optimized for use in desktop SLS systems. In the study, PA12 was turned into fiber yarns of different diameters in the melt spinning device. The fiber yarns obtained were cut and subjected to thermal treatment with Polyethylene Oxide PEO in a heated balloon mixer and powders close to spherical form were obtained. These powders, which have undergone drying and sieving processes, were printed on an SLS Selective laser sintering 3D printer with open parameter. Differential scanning calorimetry DSC, scanning electron microscopy SEM and sieve analysis were performed on powder samples. For printing samples; tensile, hardness, impact, density, melt flow index EAI, vicat softening temperature tests were performed and SEM analysis was used for microstructural examination of the samples. The results of the tests of the samples were examined and the properties of commercial and produced PA12 were compared.

 Polimer malzemeler, dünya ekonomisinin çeşitli alanlarında yaygın olarak kullanılmakta ve özellikleri hızla gelişmektedir. Eklemeli imalat Eİ gibi yeni teknolojilerin ortaya çıkışı, polimer malzemeler ve kompozitler için daha yüksek performans ve işlevsellik gibi ihtiyaçlar doğurmuştur. Polimer toz malzemeler, Eİ teknolojilerinde en çok kullanılan sarf malzemelerindendir ve ağırlıklı olarak seçici lazer sinterleme SLS teknolojisinde kullanılır. SLS, birbirini izleyen toz hammadde katmanlarını 3 boyutlu 3B bilgisayar destekli tasarım modeline göre seçici olarak sinterleyerek 3B katı bileşenleri üreten bir toz yatağında füzyon işlemidir. Bu çalışmada; Poliamid 12 PA12, fiber eritme yöntemi kullanılarak toz halinde üretilmiş ve masaüstü SLS sistemlerde kullanılmak üzere optimize edilmiştir. Yapılan çalışmada PA12, eriyik eğirme cihazında farklı çaplarda fiber iplikler haline getirilmiştir. Elde edilen fiber iplikler kesilerek ısıtıcılı balon karıştırıcı içinde Polietilen Oksit PEO ile termal işleme tabi tutulmuş ve küresel forma yakın tozlar elde edilmiştir. Kurutma ve eleme işlemlerinden geçirilen bu tozlarla, açık parametreye sahip bir SLS Seçici lazer sinterleme 3B yazıcıda baskı alınmıştır. Toz numunelerine diferansiyel taramalı kalorimetri DSC, taramalı elektron mikroskobisi SEM ve elek analizi yapılmıştır. Baskı numunelerine ise; çekme, sertlik, darbe, yoğunluk, ergime akış indeksi EAİ, vicat yumuşama sıcaklığı testleri yapılmıştır ve numunelerin mikroyapı incelemesi için SEM analizi kullanılmıştır. Numunelerin testlerin sonuçları incelenerek ticari ve üretilen PA12nin özellikleri karşılaştırılmıştır.
