Abstract

Unlike traditional manufacturing methods, 3D printing technology has been used effectively in the production of objects and parts in recent years. Today, with 3D printers, it is possible to produce prototypes or final products of designed parts quickly and efficiently. In some cases, extremely complex geometries that cannot be produced by other methods can be produced with 3D printing ( Berman 2012), (Wong ve Hernandez 2012).
Within the scope of this study, Selective Laser Sintering (SLS) 3D printer design will be realized. The first and most important step in the development of a 3D metal printing technique based on Selective Laser Sintering (SLS) or Selective Laser Melting (SLM) is to reduce the energy obtained from a laser source to specified positions on the target metal powder at certain times and situations. It is aimed to integrate the independent units (such as laser, optics, lenses, control software) in the SLS-based 3D printer system to be designed with personalized software

Seçici Lazer Sinterleme Tabanlı 3D Yazıcının Tasarımı

Abstract

Geleneksel imalat yöntemlerinden farklı olarak, 3D baskı teknolojisi, son yıllarda nesnelerin ve parçaların üretiminde etkili bir şekilde kullanılmaya başlanmıştır. Günümüzde 3D yazıcılar ile hızlı ve verimli bir şekilde tasarlanan parçaların prototip veya nihai ürün imalatını gerçekleştirmek mümkündür. Hatta bazı durumlarda başka yöntemlerle imal edilemeyecek son derece karmaşık geometriler 3D baskı ile üretilebilmektedir (Berman 2012), (Wong ve Hernandez 2012).
Çalışma kapsamında Seçici Lazer Sinterleme (SLS) 3D yazıcı tasarımı gerçekleştirilecektir. Seçici Lazer Sinterleme (SLS) veya seçici lazer ergitme (SLM) tabanlı bir 3D metal baskı tekniği geliştirilmesinde ilk ve en önemli safha, bir lazer kaynağından elde edilen enerjinin belli zaman ve durumlarda, hedef metal tozu üzerine belirlenen konumlara düşürülmesidir. Tasarlanacak olan SLS tabanlı 3D yazıcı sistemindeki bağımsız birimlerin (lazer, optik, lensler, kontrol yazılımı gibi) kişiselleştirilmiş yazılım ile entegrasyonu hedeflenmektedir.
