An integrated system and framework for development of medical applications and products based on medical imaging data

Cranial defects which are caused by bone tumors or traffic accidents are treated by cranioplasty techniques. Cranioplasty implants are required to protect the underlying brain, correct major aesthetic deformities, or both. With the rapid develop-ment of computer graphics, medical image processing (MIP) and manufacturing technologies in recent decades, nowadays, personalised cranioplasty implants can be designed and made to improve the quality of cranial defect treatments. However, software tools for MIP and 3D modelling of implants are ex-pensive; and they normally require high technical skills. Espe-cially, the process of design and development of personalised cranioplasty implants normally requires a multidisciplinary team, including experts in MIP, 3D design and modelling, and Biomedical Engineering; this leads to challenges and difficulties for technology transfers and implementations in hospitals. This research is aimed at developing, in particular, cost-effective solutions and tools for design and modeling of personalised cranioplasty implants, and to simplify the design and modelling of implants, as well as to reduce the design and modeling time. In this way, surgeons and engineers can conveniently and easily design personalised cranioplasty implants, without the need of using complex MIP and CAD tools; and as a result the cost of implants will be minimised

Quality engineering challenges on the way to sustainability

The goal of this paper is to present the author’s thoughts on the possible contribution of quality engineering to sustainable development. It is indicated that in the product life cycle designers have the greatest potential to support this challenge. Arguments have been presented to abandon the commonly accepted paradigm, according to which the overriding goal of the designer is to achieve the highest market value possible measured by the prospected level of demand for the products designed. It is postulated to include the minimization of the risks brought to the natural environment and social relations as a criterion of product design quality. To this goal, it is necessary for designers to pursue both environmentally friendly materials and technologies and design concepts reducing consumers’ pressure on continuously increasing demand. Such an approach will allow for more effective control of consumption, the main cause of the negative effects of economic growth

Uspešnost samodejnega programiranja CAM s predlogami za strojno obdelavo v proizvodnji specialnih produkcijskih orodij

The paper presents the methodology and implementation of original Automatic CAM programming using machining templates (ACPUT) dedicated to manufacturing special technological tooling. The development of ACPUT was inspired by the observation that although modern computer-aided design (CAD) / computer-aided manufacturing (CAM) systems can automatically create CAM programs, their universality makes them both difficult to use and inefficient because the programs created this way often contain errors. The presented programming procedure includes the development of specific machining templates based on technological knowledge gathered in a specially prepared database. These templates are dedicated to a group of parts characterized by the similarity of their geometric features. ACPUT makes it possible to reduce(in comparison to traditional CAM programming) the time required to develop a machining program, thereby positively impacting the total cost of tooling production. The paper aims to present results of testing the effectiveness of the use of ACPUT by technicians with different levels of experience (expert and beginner). The tests were carried out on special tooling - assembly equipment for plastic pipes, and compared program preparation time, machining time, and production costs

Measurement Methods for Flux Residue Quantity after Controlled Atmosphere Brazing of Aluminum Coolers

The Controlled Atmosphere Brazing (CAB) process together with NOCOLOKr flux is associated with the occurrence of potassium fluoroaluminate residue inside the cooler. Excess of this flux residue is known to cause gelation of the coolant, which deteriorates the efficiency of the cooler. The flux residue amount is most often measured via Atomic Absorption Spectroscopy (AAS), in accordance with DIN ISO 9964-3. This is a time-consuming measurement that requires the use of specialized equipment and costly solvents. The following article presents two innovative methods for flux residue measurement after CAB process. They include Scanning Electron Microscopy (SEM) with Energy-Dispersive X-ray Spectroscopy (EDS) and Reflected Light Microscopy (RLM) with Differential Interference Contrast (DIC) module. The accuracy of these methods has been compared to the reference AAS method to evaluate their potential as alternative, less expensive, and quicker measurement methods for determining the quantity of flux residue

Minimizing the emission of material waste in the production process of batteries

Contemporary societies are strongly dependent existentially and economically on the supply of electricity, both in terms of supplying devices from the power grid, as well as the use of energy storage and constant voltage sources. Electrochemical batteries are commonly used as static energy storage. According to forecasts provided by the Environmental Protection Agency at the global and EU level, in 2025 lead-acid technologies will continue to dominate, with the simultaneous expansion of the lithium-ion battery market. The production, use and handling of used batteries are associated with a number of environmental and social challenges. The way batteries influence the environment is becoming more and more significant, not only in the phase of their use but also in the production phase. The article presents how to effectively reduce the environmental impact of the battery production process by stabilizing it. In the presented example, the proposed changes in the battery assembly process facilitated the minimization of material losses from 0.33% to 0.05%, contributing to the reduction of the negative impact on the environment

The Natural Moisture of ABS Filament and Its Influence on the Quality of FFF Products

The article presents the results of research on the influence of the natural moisture of a filament made of acrylonitrile–butadiene–styrene terpolymer (ABS) on the mechanical properties and quality of products fabricated with fused filament fabrication (FFF). The concept of the natural moisture of the filament was defined, and the range of its variability was identified in reference to the range of the natural ambient humidity. It is shown that a change in the ambient humidity by 10% resulted in a change in filament moisture by about 0.05%. The results of the research on the moisture variability of an ABS filament stored in a package, an airtight container, or a container with a moisture absorber are also discussed. The last part of the article presents the results of the research on the impact of the moisture of the filament in its natural range of variability on select mechanical properties of filaments and products made using FFT. It is shown that this impact was significant and had a value of 1 MPa on 0.1% filament moisture
