The recent developments in Additive Manufacturing (AM) have accelerated the spread of 3D printers all over the world. Fused filament fabrication (FFF) has become the prevalent technology for use in printing typical thermoplastics. Sometimes, the nature of layer-wise production brings about the necessity of using support structures, leading to (i) increased material consumption, (ii) reduced production speed, (iii) deterioration in the part quality, and (iv) extra post-processing. To eliminate these shortcomings of FFF, researchers proposed several methods, one of which is to benefit from particular multi-axis hardware. In this study, the capability of a multi-axis FFF machine in support-less printing is introduced. The quality of the produced part is compared with that of its identical counterpart printed on a conventional (i.e., 3-axis) FFF setup.

Multi-axis 3D printing of spiral parts without support structures Fazla, Bartu; Dilberoğlu, Mecid Uğur; Yaman, Ulaş; Dölen, Melik (2021-11-01) The recent developments in Additive Manufacturing (AM) have accelerated the spread of 3D printers all over the world. Fused filament fabrication (FFF) has become the prevalent technology for use in printing typical thermoplastics.

Mechanical strength of 3D printed objects: experimental and numerical investigation Başara, Gözde; Tarı, İlker; Department of Mechanical Engineering (2017) The number of people and the industries that are using 3 Dimensional (3D) printing increases everyday; however, the home-use of 3D printing remains below expectations partially due to limitation in the printer size. Many different technolo-gies can be used in 3D printing. In this study Fused Deposition Modelling (FDM) is used. This method is commonly used for home-use 3D printing. In FDM, there is a wide range of materials that can be used and for this study the material is chosen as Poly Lactic Acid (PLA) ...
3D printing of polymeric tissue engineering scaffolds using open-source fused deposition modeling Alagoz, Ayse Selcen; Hasırcı, Vasıf Nejat (2020-08-01) Open-source printing is a field where the cost of printing additive manufacturing products is cheaper due to more economical software and parts to construct a product including those of tissue engineering scaffolds. In this manuscript, fused deposition modeling (FDM) is used as the main avenue of open-source use in 3D printing of tissue engineering scaffolds. Additive manufacturing enables the researchers to build 3D products with interior and exterior architectures precisely defined and produced using open...
Multilayer graphene growth on polar dielectric substrates using chemical vapour deposition KARAMAT, SHUMAİLA; Celik, K.; Zaman, S. Shah; Oral, Ahmet (Elsevier BV, 2018-06-01) High quality of graphene is necessary for its applications at industrial scale production. The most convenient way is its direct growth on dielectrics which avoid the transfer route of graphene from metal to dielectric substrate usually followed by graphene community. The choice of a suitable dielectric for the gate material which can replace silicon dioxide (SiO2) is in high demand. Various properties like permittivity, thermodynamic stability, film morphology, interface quality, bandgap and band alignment...
Dimensional accuracy improvement of fused filament fabrication holes utilizing modified interior Sımsek, Seyda; Yaman, Ulaş (2016-11-16) This paper proposes an alternative approach to improve the dimensional accuracy of the holes manufactured with Fused Filament Fabrication desktop 3D printers. As opposed to the state of the art techniques, where they scale the input geometric designs according to their predictive and statistical models, the proposed method modifies the interior of the artifacts with respect to the geometric properties of them to compensate for the shrinkages of the holes. That is, the shrinkage itself is utilized to elimina...
