Birdhouses and production by 3D printing method

İnceliğin estetiğe, estetiğin mimariye dönüştüğü kuşevi, yaşadığımız coğrafyada, yüzyıllar öncesi temelleri atılmış bir geleneğin, kültürel değerin günümüze ulaşan, kaybolmasından endişe duyulan izleri olarak görülebilir. Kuşevi geleneği, teknolojik gelişmeler, değişen toplum ihtiyaçları ve üretim teknikleri gibi bazı sebeplerle kaybolmaya yüz tutmuş, mevcut örnekler korunamaz olmuştur. Bu makalede, kaybolmakta olan bir geleneğin, yeni teknolojilerin kullanılması ile tekrar canlandırılması yönünde yapılan çalışmalar paylaşıldı. Bu çalışmada bir sanatın kaybolmasına sebep olan teknolojik gelişmenin aynı sanatı geri getirmekte veya yaşatmakta etkili olabileceği düşünüldü ve uygulaması yapıldı.Birdhouse with aesthetics derived from common architecture, the geographical areas we live in and traditions can be seen as traces of cultural value from centuries before. Unfortunately, since there have been changes in architectural styles and preferences, necessities and social groups, the culture of implementing bird houses into normal buildings has not been preserved. In this article, studies on the revival of a lost tradition, with the use of new technologies, were shared. In this study, it was thought that the technological development which caused the disappearance of an art could be effective in bringing back the same art

Double Stud Cargo Fitting Research, Alternative Cargo Clip Design and Analysis

In air transportation, fixing the cargo inside the aircraft is important in terms of both flight safety and operational process. Positioning and fixing of the cargo to the aircraft within a short period of time without any risk in terms of flight safety is carried out with the use of some apparatus and subsystems within the pre-determined rules. This fixation is carried out by covering the cargo loaded onto aluminium pallets. The connection of the net on the pallet is provided by metal apparatuses known as clip (Figure 1). These apparatuses are also referred to in the aerospace industry as cargo fitting, double stud cargo fitting. In this study, the design development process of these clips in the history of aviation design, the alternative clip design work we have done and the comparative analysis of this design will be discussed. Firstly, we will address our work on cargo clip in parallel with the historical development process. In this context, different systems and apparatus design studies from the 1950s until the present day will be examined in order to load and stabilize the cargo. In our review, the design development process of cargo clip, the formation of the standard product, with the patent images of the period will be detailed. In this patent review, cargo loading system designs for cargo aircraft and apparatus patent applications designed for cargo operations were utilized

With the concept of sustainability, further improvement of spatial comfort conditions has started to be demanded increasingly from designers. The fact that energy efficiency is also discussed more in design has led to the need for designers to consider these issues earlier in the design phase. The study aims to create a daylight based support model for designers. Within the scope of the model, daylight design variables and daylight design criteria are correlated and basic guidance is provided for solutions to possible problems. For this reason, daylight factors are explained in detail in a systematic way. Thus, it is aimed for architects to use these factors in the early design phase and internalize them in architectural design. The model created constitutes the support system by accepting that the designer can look at different degrees of importance and support by the designer at every stage of the design

A Novel Synchronous Scanning Strategy in Laser Powder Bed Fusion and Effect on Mechanical Properties of Industrial Gears

The effect of LPBF process parameter change on production results has been the subject of many studies. In this study, innovative synchronous scanning strategy in LPBF production system and the effect of this scanning strategy on industrial gears are discussed. The scanning strategy obtained by the synchronous use of hatch distance, stripe width, and layer thickness parameters constitutes the innovative aspect of the study. In trial productions, it was observed that the traditional melt pool form changed and the strength increased by 25% in industrial gears produced with this scanning strategy. It is thought that this synchronous parameter change creates a potential for the production of industrial components with reduced weight. The scope of the study consists of parameter studies, LPBF production, material laboratory studies, microstructure, and SEM (scanning electron microscope) examination, and compression test

A Novel 3D Printed Air-Cooled Fuel Cooler Heat Exchanger for Aviation Industry

Unmanned aerial vehicles are expected to complete their missions even in adverse weather conditions. Overheating in the engine area may occur, particularly at high speeds due to using the full engine throttle. Another design factor that affects endurance duration and maximum take-off weight is the weight of the unmanned aerial vehicle heat exchanger. In this paper, a new type of air-cooled fuel cooler heat exchanger is proposed to reduce the total weight of the heat exchanger by increasing cooling performance through the design flexibility offered by additive manufacturing. The printed circuit heat exchanger has a circular cross-section to prevent dead bends in the heat transfer surfaces and feed coolant air directly onto the fins and circulation pipes. Twisted fins and piping structure were adjusted so they could be produced without any support, generate turbulence, and reduce total weight. The fluid flow and heat transfer characteristics of novel and conventional heat exchangers were simulated in 3D. The flow physics of both exchangers were studied to determine how the new design enhances heat transfer. Numerical results showed that the new heat exchanger has 55.6% more cooling capacity than the conventional one. The heat exchanger weight was decreased from 774 to 263 g

The Novel Hybrid Lattice Structure Approach Fabricated by Laser Powder Bed Fusion and Mechanical Properties Comparison

Aluminum-based cellular structures are gaining a huge traction in several applications, including lightweight aircraft, military equipment, and heat exchangers. With additive manufacturing, the fabrication of complex periodic cellular structures with any unit cell form, size, and volume fraction has become a lot easier, allowing for more investment, research, and attention from both academia and industry. The aim of the research was to assess the manufacturability and performance of AlSi10Mg periodic cellular structures generated using the laser powder bed fusion process. Re-entrant and triply periodic and minimum surface (TPMS) gyroid cells were hybridized into a single cellular structure having identical volume fraction. Because of distinct mechanical properties of TPMS and re-entrant types, these cells were selected and assembled in various patterns to study their manufacturability, deformation behavior, energy absorption, and compressive strength. This work demonstrates good geometric agreement between the manufactured hybrid lattice structures and computer-aided design models. Hybridized structures with several repeated layers of TPMS gyroid and re-entrant cells can result in superior compressive strength and energy absorption than those with only few large layers
