Seçici lazer sinterlemede poliamid 12’ye dendritik bakır tozu ilavesinin etkisi

Öz:
Günümüzde polimer malzemeler ev eşyalarından mühendislik uygulamalarına kadar geniş bir kullanım alanına sahiptir. Bu nedenle özelliklerinin geliştirilmesi önemlidir. Katkı maddeleri ilavesi, polimer malzemelerin özelliklerini artırabilmektedir. Katkı ilave tekniği ve bileşimleri imalat yöntemine göre değişebilmektedir. Yeni bir üretim yöntemi olup kızılötesi lazer ışını ile polimer tozlarının sinterlenmesine dayanan Seçici Lazer Sinterleme (SLS) toz yataklı eklemeli imalat metodunda da katkı maddelerinin kullanılması mümkündür. Bu metotta katkı kullanımı çok yaygın olmasa da en çok tercih edilen katkı maddeleri seramik esaslı inorganik malzemelerdir. Bununla birlikte, ince metalik parçacıklar da katkı maddesi olarak kullanılabilir. Bu çalışmada dendritik bakır tozu katkılı poliamid 12'nin SLS ile prosesi incelenmiştir. İki farklı katkı içeriğindeki toz karışımları proses parametreleri belirlemek amacıyla karakterize edilmiş ve artan enerji yoğunluğunun kullanılması gerektiği saptanmıştır. Beş farklı parametre kullanılarak üretilen numunelerin fiziksel ve mekanik testleri sonucu katkı ilavesiyle eğme özellikleri ve boyutsal hassasiyet düşerken, yüzey pürüzlülüğü değişmemiş ve depolama modülü iyileşme göstermiştir.

Effect of dendritic copper powder addition to polyamide 12 in selective laser sintering

Öz:
Today, polymer materials have a wide range of usage areas that are from household goods to engineering applications. Therefore, improvements in their properties are essential. The addition of fillers can increase the properties of polymer materials. Filler addition techniques and compositions can vary with the manufacturing methods. It is also possible to use fillers in selective laser sintering (SLS) powder bed fusion additive manufacturing method, which is a new manufacturing method based on the sintering of polymer powders with an infrared laser beam. Although the use of fillers is not very common in this method, the most preferred fillers are ceramic based inorganic materials. However, fine metallic particles could also be used as fillers. This study investigates the processing of dendritic copper powder filled polyamide 12 by SLS method. Powder mixtures in two different filler contents were characterized to determine process parameters, and it was determined that increased energy density should be used. As a result of the physical and mechanical tests of the sintered samples produced using five different parameters, the bending properties and dimensional sensitivity decreased with the filler addition, while surface roughness did not change, and the storage modulus improved.
