Air pollution is one of the main environmental problems today. It is a problem which cannot be solved in many cities around the world. Sarajevo, as main capital of Bosnia and Herzegovina, is one of those cities. Few times during every year, Sarajevo is the most polluted city in the world, especially during winter season. Taking in consideration that air pollution cannot be solved on global level for one town or country, engineers are started to work on the devices that can improve air quality in small closed spaces like offices, schools or homes. This paper is focused on the design and development of an air purification device intended for indoor use, full development process is presented, from initial design to prototype manufacturing using additive manufacturing (3D printing). Keywords: Air pollution · air purification · design · development · device 1 Introduction Air quality is one of the biggest environmental problems today [1]. There are numerous studies about air quality monitoring [2, 3] and different filtrations technologies. New filtration technologies are developed constantly [4, 5]. Taking in consideration that air pollution cannot be solved on a global level, or even in one city, like Sarajevo in Bosnia and Hercegovina, there is growing research in the area of development of devices for air purification inside closed spaces like schools, offices and homes [6]. Today market is filled with air purification devices. These devices gain popularity in recent years because peoples become more informed about health problems related to low air quality. Through this paper full design and development process [7] of an air purification device intended for indoor use is presented, from initial design to prototype manufac- turing using additive manufacturing [8]. During process of development and design of a new product there is always a goal to develop a product which properties will be better in comparison to the other products available on the market [9]. Market success is depen- dent on various factors (design and development time, price, shape, customer needs, etc.). Focus of product developed in this research is on its unique design and function- ality. All parts of a device are designed for manufacturing using additive manufacturing (3D printing). This reduced manufacturing time to just few days. Goal of this design is to offer it to everyone who have some types of desktop 3D printers so everyone can © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023 I.
