Hafif yapılar günümüzde en çok çalışılan konulardan birisi olarak karşımıza çıkmaktadır. Metalden üretilen birçok makine elemanı 3D yazıcı teknolojisi ile hafif polimer malzemelerden üretilebilmektedir. Bu çalışmada, polimer cıvatalar için yeni bir üretim yöntemi önerilmiş ve baskı yönünün çekme ve kesme mukavemeti üzerine olan etkileri deneysel olarak incelenmiştir. Öncelikle cıvata şaftları farklı baskı yönleri için eriyik yığın modelleme (EYM) yöntemiyle üretilmiştir, ardından şaftların son çapları tornalama işlemi ile belirlenmiştir. Diş açmada kullanılacak olan pafta için özel bir aparat tasarlanmış üretilmiştir. Cıvata dişleri bu özel aparat kullanılarak pafta ile açılmıştır. Ġmalat sürecinden sonra, üretilen çekme ve kesme test numunelerinin performansları çekme ve kesme testleri ile belirlenmiştir. Çekme ve kesme testleri için ayrıca özel aparat tasarımları da gerçekleştirilmiştir. Gerçekleştirilen çekme ve kesme testleri sonucunda baskı yönünün cıvataların çekme ve kesme dayanımları üzerinde oldukça etkili olduğu görülmektedir. 0º üretim açısı ile üretilen cıvataların dayanımının en yüksek, 45º ile üretilen cıvataların dayanımının ise en düşük olduğu belirlenmiştir.

Lightweight structures are one of the most studied topics today. Many metal machine elements can be produced from lightweight polymer materials with 3D printer technology. In this study a novel manufacturing method is proposed for the polymer bolts and the effects of the printing directions on the tensile and shear strength are investigated experimentally. Firstly the bolt shafts are produced FDM method by using 3D printer for different print orientations and the final diameters of the bolt shafts are determined by the turning process. A special apparatus is designed and manufacture for threader tool. The screw pitches are opened by using this special apparatus with threader tool. After the manufacturing process, the performance of the produced tensile and shear test samples are defined by using tensile and shear tests. A special tensile test apparatus is also developed in this study. It is seen that the printing orientation has great effects on the tensile and shear durability of the bolts. It has been determined that the strength of the bolts produced with a production angle of 0º is the highest, and the strength of the bolts produced with 45º is the lowest.
