AB  - Bu çalışmada son yıllarda gelişim göstererek endüstrinin temel imalatmetotlarından biri haline gelen eklemeli imalat üzerine, imalat süresi,süreçleri ve maliyetler ekseninde çeşitli analizler gerçekleştirilmiştir. Tozyatak birleştirme teknolojilerinden bir tanesi olan “Doğrudan metal lazersinterleme” (DMLS) metodunun işlem süreleri ve süreç analizinin yapılmasısonucunda literatürde yer alan mevcut denklemler ve ilave olarak imalatın tümadımlarını ve her türlü gideri hesaplamaya dâhil ederek genel bir maliyet vesüreç hesaplaması denklemi türetilmiştir. Elde edilen denklem Türkiye örneklemiüzerinden kontrol edilmiş ve Türkiye şartlarına yönelik bir çalışma yapılmıştır.Geliştirilen model ile imal edilmesi planlanan parçaların DMLS ile eklemeliimalat süreleri, imalat verimliliği ve etkin tezgâh kullanımı hakkındakiverilere ulaşabilmek mümkün hale gelmiştir. Bunların yanında imalat tezgâhlarınamortisman hesapları ve başa baş noktası analizleri farklı işletme şartlarındaincelenerek gerçekleştirilmiştir.

N2  - In this study, various analyzes have been carried out in terms ofmanufacturing time, processes and costs on the additive manufacturing, whichhas become one of the basic manufacturing methods of the industry. As a resultof the processing times and process analysis of the "direct metal lasersintering" (DMLS) method, one of the powder bed fusion technologies, ageneral cost and process calculation equation has been derived, including theexisting equations in the literature, plus all steps of manufacturing and allsorts of calculations . The resulting equation was checked on the samplingTurkey and a study was carried out for the conditions of Turkey. With thedeveloped model, it is made possible to reach the data about the manufacturingtime, manufacturing efficiency and effective use of the machine with DMLS partsplanned to be manufactured. In addition, amortization calculations andhead-to-head analyzes of manufacturing machines were carried out underdifferent operating conditions.
