Research on Structural Design and Parametric Modeling of Trestle of Material Ropeway of Transmission Line

Aiming at the trestle of material ropeway of transmission line, the structural design of components was carried out with the combination of 3D design software. Parametric modeling method was adopted to carry out the modeling of components with different structural parameters. The stress status of components of trestle was analyzed, the design load of components was proposed, and the strength of the designed components was checked through finite element simulation analysis. The results show that the components can meet the requirements of structural strength. The proposed method can realize parametric modeling of solid model and effectively improve the design efficiency of material ropeway.

Manufacturing Multicolor LED-Based Phototherapy Device with a Novel 3D Design

Jaundice is a condition that results from an increase in bilirubin level in the blood. Its prevalence in newborns is around 60-70%. When this temporary jaundice becomes pathological and left untreated, significant damages may occur such as brain damage, vision loss, lung and kidney dysfunction, and even death. One of the methods used for the treatment of jaundice is phototherapy. In this study, a design has been made with 3 foldable LED panels to increase the target area. In addition, high-voltage LEDs with blue-green white wavelengths were used. Thus, it was aimed to minimize the risks of nausea and dizziness caused by intense blue light. An automatic system has been achieved by using temperature and light intensity sensors. The system will warn the user at temperatures and light intensity that are harmful to the baby.

Concurrent Engineering and based Applications for 3D Big Data

European companies’ competitiveness depends on obtaining innovative products. In the last years, clients demand started to be higher and more complex. Because of that, managing products development processes have become a necessity. Product development processes need to be proficient and flexible: less complex and more competence-focused. 3DSpace brings more solutions in this matter. EXALEAD transforms large volumes of heterogeneous, multi-source data into real-time information intelligence to help users improve business processes and gain competitive advantage. EXALEAD enables organizations to gather and enrich Big Data to deliver that information in the process of integrated product development and allows customers to fully manage product programs, from 3D design to traceability of changes, cost, quality and issue analytics. Concurrent or Simultaneous Engineering is one of the fundamental approaches that meet the challenges mentioned above. EXALEAD uses CloudView to process big data flows. Concurrent Engineering represents a standardized approach to integrated product improvement which accentuates and gives priority to the customer expectations level. In this matter, 3DSpace’s ENOVIA is used together with graphic software for manufacturing. It is about teamwork and confidence in which the decision-making process is consensual, even from the beginning of the product life cycle.

Digital Creativity Development in an E-learning Environment – A 3D Design Project

During the pandemic, arts disciplines had to seek new paths for creation to continue visual skills development outside the studio. ICTs offer a natural tool set for individual and collaborative work and sharing online. 3D design and the development of digital creativity can represent new directions for Hungarian art education and its major discipline called Visual Culture. With this tool, visual art education can proceed on the bumpy road to teach the visual language of the 21st century. Certainly, technological focus is not the only option for progress in art education. Nevertheless, if we look for possible directions for renewal, we cannot ignore the use of software products that support visual creativity,and are becoming more and more easily available, simpler and free of charge. This paper focuses on the pedagogical possibilities of 3D printing. We present an experimental program with secondary school students aged 16 years, that started and ended face-to-face and was partly realised online. As the project manifests a creative synergy of Visual Culture and Information Technology disciplines that may be of interest for art and ICT educators as well.

Effect of infill density and raster angle on the mechanical properties of PLA

Polylactic acid (PLA) is derived from natural aliphatic polyester resources for instance sugarcane or starch based plants. PLA also known as a biocompatible and biodegradable thermoplastic and found widely in multiple applications like electronic and electrical devices, biomedical, food packaging and the engineering field. PLA have attracted attention in production potential due to its superior attributes like ease of processing, high strength and high modulus. Infill density, raster angle and infill pattern can influence the mechanical characteristics of materials like PLA, acrylonitrile-butadiene-styrene (ABS), polyetheretherketone (PEEK). In this paper, the relationship between infill density and raster angle was studied to investigate the mechanical performances of PLA by using 3D printers. 3D printing is used to fabricate more complex 3D design objects. The tensile test was involved to evaluate the properties of pure PLA. For pure PLA, 0° raster angles with 100% infill density show the highest tensile strength and Young’s modulus which are 28.926MPa and 1262.7MPa respectively. However, a decreasing trend of break elongation reveals in PLA as infill density increases for both 0° and 90° raster angle. Optimization of printing parameters become crucial to provide high quality materials for 3D printing in order for education, packaging, engineering and biomedical applications.
