The objective of this study was to investigate pore shape effect on resistance to compression of open porosity lattice structures obtained with 3D printing. To this end, three distinct pore architectures were investigated: ellipsoidal, helical and X-shape. Open porosity of these structures was 54%, 50% and 60%, respectively. Their mechanical proper...

The development of additive manufacturing (AM) techniques has sparked interest in porous structures that can be customized in terms of size, shape, and arrangement of pores. Porous lattice structure (LS, called also lattice struct) offer superior specific stiffness and strength, making them ideal components for lightweight products with energy abso...

This work presents an assessment of the performance of five deep learning segmentation models (DeepLabV3, FCN, LinkNet, SegNet, and U-Net) as tested on the microstructure of various Al–Si alloys with the goal of providing a more objective visual inspection of microscopic images. A variety of metrics, including Pixel Accuracy, Sensitivity, Recall, D...

This study characterizes the “balling” features on orthodontic brackets fabricated by LPBF in the context of their potential for mechanical interlocking with polymeric coatings. The ball-like features (BLFs) were quantitatively analyzed in terms of their size, shape, and spatial distribution using digital light microscopy (LM), scanning electron mi...

This study investigates the mechanical performance of interlock patterns printed on metallic substrates under separation conditions. Polymeric parts (PEEK and Trogamid) were joined to metallic counterparts using axially symmetric mushroom-shaped interlocking structures. These structures were fabricated through the direct energy deposition process,...

Additive Manufacturing (AM) is one of the most studied technologies to produce different parts today. Large-scale additive manufacturing (LSAM) is used to produce complex parts without further technological processes and for the production of large-sized polymer parts. In order for the parts produced from polymer materials to show better mechanical...

This study presents an analysis of the mechanical behavior of different amounts of carbon fiber additive ABS composites produced by the large-scale additive manufacturing (LSAM) method. Additive manufacturing is distinguished from other manufacturing methods such as casting, molding, machining or etc. by its ability to obtain complex parts by this...

Reverse engineering (RE) aims at the reproduction of products following a detailed examination of their construction or composition. Nowadays, industrial applications of RE were boosted by combining it with additive manufacturing. Printing of reverse-engineered elements has become an option particularly when spare parts are needed. In this paper, a...

The parts produced by additive manufacturing are inherently subjected to discretization effects due to their layer-based addition. The stair-stepping effect on the surface quality is inevitable for most of the techniques and it becomes more dominant for the regions having small surface inclinations. The stair-stepping influences the mechanical prop...

Hybrid Additive Manufacturing (Hybrid-AM) describes multi-operational or multi-functional additive manufacturing systems. In industry, the increasing tendency in applications of Hybrid-AM brings up the challenge of improving novel methods for the manufacturing of new or hybrid parts. Hybrid AM can produce fully functional assemblies without any ass...

Sheet metal bending is one of the important metals forming processes at ambient temperature. The usage of high-strength steel is one of the stronger materials for the construction of components in the automotive industries. However, for complex shapes, cold forming is not always sufficient, and heating the workpiece plays a major role in manufactur...

The mass production bevel gears is mainly realized by precision forging process. The process can be carried out cold, warm or hot conditions by using various forging presses (hydraulic or mechanical presses and High Energy Rate Forming machines). The process cycle time is changing with the type of forging press (i.e. the speed of punch). During hot...

Asimetrik dişliler özellikle tek yönlü güç ve hareket iletiminin olduğu uygulamalarda simetrik dişlilere göre daha üstün performansları nedeniyle tercih edilmektedirler.

Asymmetric gears have been attracting an increased interest in the industrial gearbox applications. This is because of their inherent advantages over symmetrical gears. However, the measurements of the asymmetric gears have difficulties due to the asymmetry of tooth profile. In this study, a non-contact measurement method based on image processing...

Asymmetric gears have some advantageous in one directional motion. But, due to the profile geometry, the production with the conventional cutting method limits the design of the profile. Recent studies in this area have shown that asymmetric profiles designed independently from the cutting tool are more efficient. Therefore, in this study, a precis...

Wire Arc Additive Manufacturing (WAAM) is a relatively new manufacturing method.
