After the expiration of the patent on the Fused Filament Fabrication (FFF) type of additive manufacturing method, people have started various technological companies to improve the process and its fundamental equipment. One of these advancements was on the slicing plane orientation of the FFF 3D printers. Instead of having the conventional horizontal slicing planes, few companies developed similar 3D printers capable of extruding material at a fixed angle of inclination. Another great advantage of their configuration is that the printer has an infinite building volume, which enables mass production with the FFF process. The problem with this approach is that the inclination angle of the 3D printer is fixed and it may be inefficient for the fabrication of various parts. In this study, a novel slicing methodology is implemented using Rhino3D (CAD software) and Grasshopper3D (analytical modeling tool for Rhino3D) environments with adaptive slicing planes. Later, a conveyor belt is integrated onto a multi-axis 3D printer to realize the proposed approach. Several parts are fabricated and the advantages of the method are elaborated over these example artifacts.

A Cloud Manufacturing Application for Additive Manufacturing Methods Haseltalab, Vahid; Yaman, Ulaş (2019-01-01) Over the past years, the manufacturing industry has witnessed a great enhancement in the field of Additive Manufacturing that allows forming an inchoate market to produce custom-made products with low unit costs. At the same time, everyone may be a designer as well. However, the required equipment is only accessible for all the people. The Cloud Manufacturing aims to resolve this challenge by connecting the customers to the manufacturers. Therefore, this paper introduces a practical fabrication method for 3...
Characterization of novel materials for fused filament fabrication AL-DUAIS, ABDULLAH ABDULRAHMAN NAJI; Özerinç, Sezer; Kazanç Özerinç, Feyza; Department of Mechanical Engineering (2021-6-24) Fused filament fabrication (FFF) is a polymer additive manufacturing technology that is suitable for a wide range of applications due to its low cost and ease of use. This thesis investigated two types of novel materials for FFF use. First, a foaming PLA filament is considered and the mechanical properties of 3D printed specimens using this filament is characterized. The results show that the strength, modulus and density of the foaming PLA can be tuned over a wide range of values by varying FFF process par...
An Automated Design and Fabrication Pipeline for Improving the Strength of 3D Printed Artifacts under Tensile Loading AL, Can Mert; Yaman, Ulaş (2018-04-25) In the scope of this study, an alternative automated method to the conventional design and fabrication pipeline of 3D printers is developed by using an integrated CAD/CAE/CAM approach. It increases the load carrying capacity of the parts by constructing heterogeneous infill structures. Traditional CAM software of Additive Manufacturing machinery starts with a design model in STL file format which only includes data about the outer boundary in the triangular mesh form. Depending on the given infill percentag...
A Modeling Study on the Layout Impact of with-in-die Thickness Range for STI CMP Kıncal, Serkan; BAŞIM DOĞAN, GÜL BAHAR (2012-10-01) Chemical Mechanical Planarization process has a proven track record as an effective method for planarizing the wafer surface at multiple points of the semiconductor manufacturing flow. One of the most challenging aspects of the CMP process, particularly in applications like Shallow Trench Isolation (STI), is the difference in relative removal rates of the different materials that are being polished. A certain amount of over-polish is required to clear oxide on top of the nitride, however, this over-polish m...
A composite dislocation cell model to describe strain path change effects in BCC metals Yalçınkaya, Tuncay; Geers, M.G.D. (IOP Publishing, 2009-11-16) Sheet metal forming processes are within the core of many modern manufacturing technologies, as applied in, e.g., automotive and packaging industries. Initially flat sheet material is forced to transform plastically into a three-dimensional shape through complex loading modes. Deviation from a proportional strain path is associated with hardening or softening of the material due to the induced plastic anisotropy resulting from the prior deformation. The main cause of these transient anisotropic effects at m...
