Building Project

There were a number of recent construction methods and materials introduced in the 21st century however, because of lack of data, the implementation of a new construction techniques or a replacement material, the limits of architecture and design have not changed considerably, as will the construction methods. Like the building project. In a broad spectrum of fields, the world of foodstuffs, and user management components, technology also showed promises. Similar with any or all sectors, the building industry continues to support the production of 3D printers. 3D printing should not be underestimated because it reduces the scope of key factors such as growth, the cost of the product and the duration of the entire undertaking. The discovery of new printable, refining shapes, and the regular properties of 3D written concrete will realize this inspiring technique in observation.

Foundation piles that are made by concrete 3D printers constitute a new alternative way of founding buildings constructed using incremental technology. We are currently observing very rapid development of incremental technology for the construction industry. The systems that are used for 3D printing with the application of construction materials make it possible to form permanent formwork for strip foundations, construct load-bearing walls and partition walls, and prefabricate elements, such as stairs, lintels, and ceilings. 3D printing systems do not offer soil reinforcement by making piles. The paper presents the possibility of making concrete foundation piles in laboratory conditions using a concrete 3D printer. The paper shows the tools and procedure for pile pumping. An experiment for measuring pile bearing capacity is described and an example of a pile deployment model under a foundation is described. The results of the tests and analytical calculations have shown that the displacement piles demonstrate less settlement when compared to the analysed shallow foundation. The authors indicate that it is possible to replace the shallow foundation with a series of piles combined with a printed wall without locally widening it. This type of foundation can be used for the foundation of low-rise buildings, such as detached houses. Estimated calculations have shown that the possibility of making foundation piles by a 3D printer will reduce the cost of making foundations by shortening the time of execution of works and reducing the consumption of construction materials.

Air Leakage Rate

Air leakage is one of the main influencing factors in buildings’ thermal performance. The adverse effects of poor air leakage include higher energy costs, consumption in space heating and cooling, poor thermal comfort, corrosion, and the growth of molds due to air leakage induced condensation. The main objective of this study is to investigate the characteristics of air leakages of Canadian homes related to construction methods, age, size and climatic zones. The air leakage test results of 226,000 dwellings in three provinces of Canada were analyzed. Statistical analysis was utilized to compare the mean of air leakage with respect to different factors. Generally, the air leakage decreased by 40% in the period from 1960 until 2018, which has shown a remarkable effect of new construction techniques on air leakage. Investigations also indicated that the average air leakage rate of homes constructed by using the onsite technique is approximately 25% to 60% higher than those prefabricated in modular or panels, varying with respect to the workmanship and construction quality control. This study concluded that the prefabricated construction techniques could decrease the air leakage rate significantly, which will have a remarkable effect on buildings’ thermal performance as well as home’s heating and cooling costs. The findings contribute to estimating the effects of influencing factors on air leakage, also it is useful in performance simulations, HAVC sizing and energy management. And recommend the use of the prefabricated in modular or panel’s construction method to achieve better and acceptable air leakage performance.

High Energy Consumption

This paper is to bring into knowledge, a proficiency, which would help us to fight against energy crises using new construction techniques. It discusses the needs and benefits of sustainable Green buildings. It focuses on coming up with new ideas to build green buildings with minimum Embodied Energy. High energy conservation in buildings can be achieved by insulating materials (powerful device for designing and building) and by improving the construction envelope heat safety, which then controls the building envelope's transmissivity. Since the orientation of buildings and their protection from the sun cannot be implemented freely in the urban environment where it is densely built, heat insulation and adoption of bioclimatic architectural principles becomes the need. Green buildings, at the decreased ranges of consumption of resource and energy, the design of green buildings will meet the needs of users. This is a wise approach to use India’s energy in this period of crisis. These buildings will replace most of our present building methodologies. “Energy can neither be created nor destroyed”, hence application of this paper is aimed at utilizing the irrelevant energy consumed in building processes and providing comfort at the cost of sustainability.

This research was initiated to develop low cost powders that could be used on 3D printers. The paper describes experiments that were undertaken with different compositions of clay-based powders, and different print saturation settings. An unexpected sideeffect of printing ceramic parts was the ability to control the part porosity by varying the powder recipe and print parameters. The cost of clay-based powder was, depending on the specific ingredients used, around US$2.00/Kg.

The 1960S

In Alberta, Canada during the 1960s and early 1970s the popularity of recreational paddling expanded considerably. The reasons for this were varied, including wider demographic and economic shifts that produced a population that was both able, with time and the means, and eager to engage in these activities. But at the same time there was a notable change in the material reality of the sport brought on by the development of new construction techniques and materials. The goal of this article is to investigate the changing nature of recreational paddling in the 1960s and 70s with a focus on the influence that changing materials and construction methods had on these processes. Developed for other commercial purposes, fiberglass provided paddlers in Alberta with a means of constructing more robust canoes cheaply, quickly, and with a great deal of customization. To facilitate this construction, paddlers came together to share knowledge, materials, designs, and labor. In turn, these boatbuilding workshops became the nucleus of a budding and ultimately vibrant paddling community in the province. Moreover, the increased durability and design adaptability allowed paddlers to push the limits of the sport and successively redesign and further specialize the boats allowing for even greater skill development.

The paper presents the possibility of using an innovative hydroxyapatite filament Ca10(PO4)6(OH)2 for printing in 3D printers of bone implants and the possibility of using it during implantation with voice prostheses. The introduction of an additional colloidal silver composite in voice implants will contribute to the reduction of bacterial infections, fungal infections and granulomatous hyperplasia. The creation of a stable external ring of the vocal fistula will remove complications associated with it with enlargement of the fistula and leakiness of voice implants. The ability to print with a hydroxyapatite filament will allow digital pre-surgery modeling of bone implants suited to the needs of surgical procedures.

While assistive technology is often suggested as a way to increase, maintain, or improve functional ability for individuals with disabilities within physical activity (PA) settings, cost and availability of such items are often noted as barriers. In recent years, 3D printing has become available to the general public through the adoption of 3D printers in schools, libraries, and universities. Through individual design and rapid prototyping, 3D printing can support physical educators in accommodating student need for assistive technology through a multitude of modification possibilities. This article will highlight the capacity for 3D printed assistive technology within educational settings, and will illustrate how teachers, APE specialists, and other related service personnel can utilize this technology to support student success in PE and PA settings. This article will also assist practitioners with locating, uploading, and utilizing existing collections of 3D assistive technology models from open-source websites, such as Thingiverse.
