Nowadays education and research promote interdisciplinary cooperation and development. An interdisciplinary approach creates change and new opportunities for design education in general, while innovation, the use of advanced materials and technologies transforms design technology studies. These changes affect the development of design technology as an integrated interdisciplinary direction, the creation of innovative solutions, products and services in research design activities. This process is facilitated by research grant projects involving students and researchers. The performed experimental research in Rezekne Academy of Technologies (RTA) engineering research centres shows the possibilities of laser processing and 3D printing in textile fabrics design, promotes innovative technological solutions in product design and ensures the development of scientifically based results. The aim of the research is to improve students' independent research activities in purposeful project activities by interacting with various engineering research centers. Research methods used: theoretical - literature and Internet resource research and analysis, empirical - action (case study) research. Eight students of engineering/design study programs and four lecturers – researchers - participants of grant projects - participate in the research. Research period 2017–2020. The research has a practical significance, because it substantiates the interdisciplinary experimental research activity process and results, determining of students' independent research activity improvement direction, promotes the transfer of research results into practice.

“…The application of laser technology in non-traditional machining processes, particularly in the fields of cutting, marking, and engraving [1][2][3][4][5], has made the technology well-known in recent years. The whole phrase "Light Amplification by Stimulated Emission of Radiation" is where the abbreviation "laser" comes from [6][7][8].…”

“…Because the aforementioned method required a significant quantity of energy or power, the laser was able to successfully sever and remove the material. Subsequently, over the course of the marking process, it was seen that the material underwent very little changes in terms of the inherent attributes it possessed [3,5,17]. In the context of the technique of engraving, it has been found that variations in the characteristics of the material and the structure of the material are more prominent and visually evident.…”

The investigation of the laser engraving process has been the focus of a significant amount of research in the field of laser machines. On the surface of the material, gaps and imperfections will appear as a natural result of the engraving process. It is widely held that the surface texture of a material has a significant impact on the material's mechanical qualities, as well as its functional performance and aesthetic appeal. As a result, the purpose of this study is to investigate the influence that different process parameters have on the PMMA (polymethylmethacrylate) surface during the engraving process. PMMA was used throughout this investigation in the engraving process, which was carried out by a machine equipped with a 40W CO2 laser tube. In order to explore the effect that laser engraving has on materials, a total of 25 separate experiments were carried out in line with the Taguchi design principles. It has been investigated how surface roughness (Ra), as well as total machining time, is affected by the laser power, scanning speed, scan gap, and nozzle distance that are considered to be input factors. According to the findings, the surface roughness of the sample had a value that varied from 0.810 to 5.159 micrometres when measured in terms of distance. The factor that has the greatest influence on the Ra value is the scanning speed, which is followed by the nozzle distance, laser power, and scan gap. On the other hand, the amount of time necessary for the machine to finish engraving on the sample can range anywhere from 58 to 135 seconds, with the scanning speed being the characteristic that has the most influence on this figure.
