Design and Manufacturing of a Novel 5-DOF FDM Printer Based on Parallel Kinematic Structure

Abstract

In this study, the mathematical analysis and design of a new 3D printer with 5 degrees of freedom was carried out. Thanks to the developed system, a new concept has been brought to the multi-axis 3D printer mechanisms and thus, it is aimed to improve the part quality in additive manufacturing (AM) processes. First of all, the kinematic analysis of the system was obtained using vector algebra and the work space of the current printer was determined by considering the system constraints. Then, by giving detailed information about the mechanical and electrical components of the designed system, the working principle of the whole system is presented. According to the findings obtained in the studies, the kinematic analyzes performed for the proposed system proved to be correct and a new system was proposed especially for additive manufacturing technologies.

Paralel Kinematik Yapıya Dayalı 5-DOF FDM Yazıcı Tasarımı ve İmalatı

Öz

Bu çalışmada, 5 serbestlik derecesine sahip yeni bir 3 boyutlu (3B) yazıcının matematiksel analizi ve tasarımı gerçekleştirilmiştir. Tasarlanan sistem sayesinde, çok eksenli 3B yazıcı mekanizmalarına yeni bir konsept kazandırılmış ve böylece eklemeli imalat (AM) süreçlerinde parça kalitesini iyileştirilmesi hedeflenmiştir. Öncelikle sistemin kinematik analizi vektör cebri kullanılarak elde edilmiş ve sistem kısıtlamalarını dikkate alınarak yazıcının çalışma uzayı belirlenmiştir. Ardından tasarlanan sistemin mekanik ve elektriksel bileşenleri hakkında detaylı bilgiler verilerek tüm sistemin çalışma prensibi sunulmuştur. Tasarım çalışmalarında elde edilen bulgulara göre önerilen sistem için gerçekleştirilen kinematik analizlerin doğru olduğu kanıtlanmış ve özellikle eklemeli imalat teknolojileri için yeni bir sistem önerilmiştir.
