PARAMETERS USED IN METAL BINDER JETTING ADDITIVE MANUFACTURING

Öz

Nowadays, with the development of technology, alternative ways have been sought for functional parts that cannot be manufactured by traditional methods. One of these unconventional manufacturing methods is Additive Manufacturing. Additive Manufacturing does not work by removing the part to be manufactured from a raw material or by mass shaping, unlike traditional methods. It is a system that manufactures cross-sections of powder or melt raw material in layers according to a suitably prepared design. It can be divided into sub-types according to the type of material, the way the layers are combined and the unifying energy source, and it can be defined as the production method in which the part is manufactured as desired. As one of the Additive Manufacturing methods, Metal Binder Jetting is a recently emerged and still developing Additive Manufacturing method. Due to the fact that it is under development, a clear binder type, ratio, sintering process and atmosphere could not be determined. In this article, powder raw materials (raw material type, powder size), sintering processes (sintering temperature, time, atmosphere) and the ratio of binders used with raw material metal powder in various studies are mentioned.

BAĞLAYICI PÜSKÜRTMELİ METAL EKLEMELİ İMALATTA KULLANILAN PARAMETRELER

Öz

Günümüzde teknolojinin de gelişmesiyle geleneksel yöntemlerle imal edilemeyen fonksiyonel parçalar için alternatif yollar aranmaya başlanmıştır. Bu geleneksel olmayan imalat yöntemlerinden biri de Eklemeli İmalat’tır. Eklemeli İmalat (Additive Manufacturing), geleneksel yöntemlerin tersine, imal edilecek parçanın daha kaba bir ham maddeden eksilterek ya da kütlesel şekillendirmeyle çalışmaz. Uygun biçimde hazırlanmış bir tasarıma göre toz ya da ergiyik ham maddesinden kesit alanların katmanlar halinde imal eden bir sistemdir. Malzeme cinsine, katmanların birleştirilme biçimine ve birleştirici enerji kaynağına göre alt türlere ayrılarak, istenilen şekilde parçanın imal edildiği üretim yöntemi olarak tanımlanabilmektedir. Eklemeli İmalat yöntemlerinden biri olan, Bağlayıcı Püskürtmeli Metal Eklemeli İmalat yakın zamanda ortaya çıkmış ve hala gelişmekte olan bir Eklemeli İmalat yöntemidir. Gelişme aşamasında olmasından dolayı net bir bağlayıcı türü, oranı, sinterleme süreci ve ortamı belirlenememiştir. Bu makalede çeşitli çalışmalardaki kullanılan toz hammaddelerden (hammadde türü, toz boyutu), sinterleme süreçlerinden (sinterleme sıcaklığı, süresi, ortamı) ve kullanılan bağlayıcıların hammadde metal tozu ile oranlarından bahsedilmiştir.
