“…In hard-to-reach areas, soaking in an aqueous solution of 10-20% NaOH followed by water jet rinsing can be used to remove residual support material. The high resolution and large printing capabilities of 3D printers allow us to design and print custom shapes and parts required for aperture fabrication [21][22].…”

The aim of this study was to systematically describe the additive manufacturing (AM) technologies used for various casting technologies and how rapid investment casting (RIC) is changing the field of casting. The capability and effectiveness of additive manufacturing to provide investment casting production solutions has been investigated. The traditional investment casting method is less efficient in terms of cost and time to develop new wax models of solid tooling for low volume production or prototypes. To overcome this problem, it is proposed to introduce additive manufacturing to these processes to produce investment casting models. This paper discusses specific applications of rapid prototyping in this area. The study concluded that the use of additive manufacturing for investment casting instead of the traditional method is more cost- and time-efficient.

“…To find relationships among surface roughness parameters (Ra, Rz), the surface incline angle relative to the recoater, and the angle between the building platform and examined surface, a test sample was developed (see figure 1). [12][13] The print modes of the test sample are listed in the table. During the printing process, ISO 5832-4 material was selected for stability, P refers to power, V indicates speed (in mm/s), and layer height is represented by h (in mm).…”

Layered manufacturing (LM) technology has the capability to fabricate 3D physical models efficiently, overcoming the limitations of geometric complexities. However, the surface quality of LM-processed parts often falls short compared to parts made through traditional numerically controlled manufacturing technology. This issue of surface roughness has become a significant concern, despite the numerous potential advantages offered by LM. To address this, an elaborate methodology is proposed to predict the surface roughness of LM-processed parts. The proposed methodology takes into account both theoretical and real-world characteristics of surface roughness distributions to accurately reflect the actual roughness distributions in the predictions. This methodology was tested and used to evaluate properties of the H15N5D4B and KH28M6 materials. To achieve this, a design of the testing sample was developed, and a roughness distribution expression was introduced, utilizing measured roughness data from the aforementioned sample. This expression allows engineers to obtain surface roughness values for all surface angles, i.e., desired 3D models. The methodology also includes a prediction application, which demonstrates the validity and effectiveness of the proposed approach through several application examples.

“…The method is consistent with principles 2 (fullness of the use of raw materials) and 8 (exclusion of intermediate products), and because of non-renewable raw materials, the presence of waste and high energy costs, it contradicts rules 1, 6 and 7. To carry out all the above operations, some special conditions for the premises are required [20,21].…”

This paper presents a study on the production of hydrogen and “green chemistry”. The introduction introduces the terminology and historical data, followed by the defining principles that describe hydrogen production methods using natural gas, coal, water and biomass as feedstock. Some basics of “green chemistry” are also given. The next section provides an analysis of all hydrogen production methods, the results of the analysis are recorded in a table that allows you to identify the most environmentally friendly solutions. In the conclusion it is stated that the results of the study indicated in the table make it possible to assess the compliance of each of the 13 methods for producing hydrogen with the principles of “green chemistry”, and the assessment and comments do not take into account the economic component of technologies, the main emphasis is on environmental protection.
