Opis:
The paper presents an application of additive method of Fused Deposition Modeling for manufacturing of small series of elastic models. Additive FDM technology is used to produce a casting mould for multiple use. Process of manufacturing of small series of products consists in casting a two-component silicone rubber degassed using vacuum chamber into a multiple use mould. The paper shows the course of the process and related problems on the example of industrial product – a cylindrical seal. The casting mould was produced out of ABS material using BST 1200 machine, whereas casted elastic models were made out of XTX 45 silicone rubber.

Opis:
The paper presents a method, developed by the authors, for manufacturing polymer composites with the matrix manufactured in a layered manner (via 3D printing – Fused Deposition Modeling) out of a thermoplastic material. As an example of practical application of this method, functional prototypes are presented, which were used as elements of foundry tooling – patterns for sand molding. In case of manufacturing prototype castings or short series of products, foundries usually cooperate with modeling studios, which produce patterns by conventional, subtractive manufacturing technologies. If patterns have complex shapes, this results in high manufacturing costs and significantly longer time of tooling preparation. The method proposed by the authors allows manufacturing functional prototypes in a short time thanks to utilizing capabilities of additive manufacturing (3D printing) technology. Thanks to using two types of materials simultaneously (ABS combined with chemically hardened resins), the produced prototypes are capable of carrying increased loads. Moreover, the method developed by the authors is characterized by manufacturing costs lower than in the basic technology of Fused Deposition Modeling. During the presented studies, the pattern was produced as a polymer composite and it was used to prepare a mold and a set of metal castings.

Opis:
The paper presents a novel methodology of building industrial Virtual Reality applications with use of a knowledge-based approach. Virtual Reality is becoming more and more widespread in engineering applications. However, most solutions are immediate and not flexible, especially in maintenance. Traditional way of programming VR applications makes all the knowledge about a product or a process hard-coded, effectively losing access to it from the outside of the programming software. Besides, making new solutions without any methodology whatsoever makes the process longer and less effective. The author proposes to use general rules of available Knowledge Engineering methodologies in order to make the process of building VR applications more effective and to ensure their flexibility and access to stored knowledge, even after an application is deployed. The presented methodology is supported with practical case studies.

Opis:
The paper presents results of experiments aimed at determination of range of critical orientation for parts manufactured additively using the Fused Deposition Modelling method, out of ABS material. Numerous previous observations of plastic parts manufactured additively using the FDM process allowed concluding, that change of values of the manufacturing orientation (i.e. direction of layer slicing plane) has large influence on the macrostructure of obtained parts, thus affecting their strength and behaviour under load – the material behaves either as a thermoplastic with a yield point or as a brittle material with no yield point. The paper presents methodology and results of experiments aimed at determination of a certain value or value range, at which transition between the two behaviours occurs. The experiments consisted of tensile tests performed on samples manufactured additively in a pre-selected range of orientations. The obtained results – a value range valid for the selected type of load and sample shape – will be useful in future to help select an optimal orientation of part for a defined task.

Opis:
Fused Deposition Modelling technology allows to produce elements of very complex shapes without any additional tooling, which is why it has a broad range of industrial applications. Possibility of manufacturing parts with controlled degree of internal filling allows to shorten the manufacturing time and reduce volume of used material. The paper presents influence of layer filling type on part capability of carrying loads and economical coefficients of the manufacturing process. A problem of mechanical properties is important especially in case of elements used as functional prototypes. The paper presents methodology and results of experimental strength tests of samples with various types of internal filling. As a build material for test samples, ABS material was used. Composite samples were also used the ABS matrix produced by Fused Deposition Modelling was filled with chemically hardening polyurethane resin in a process developed by authors. The samples were subjected to destructive testing and their strength properties were compared.

Opis:
The paper presents results of studies undertaken by the authors, aimed at determination of character of influence of marker arrangement on real-time measurement of position and orientation of an object, using an exemplary optical tracking system PST-55. Such a system can be used for interaction in immersive Virtual Reality applications. To ensure better immersion of a user in a virtual environment, it is necessary to directly translate its actions into 3D image presented by the VR application. It is possible, among other things, by the application of systems for tracking user’s movements. During the presented studies, an object with infrared-reflective markers deployed on its surface was placed in the center of a rotary table, then it was measured by the tracking system to determine the influence of the object angular position on the accuracy of determination of its position and orientation by the examined device. The measurements were performed for several different arrangements of markers, to formulate guidelines for their deployment on objects used for work in a virtual environment.

Opis:
Biochemical Oxygen Demand (BOD) is an important factor used to measure water pollution. This article reviews recent developments of microbial biosensors with respect to their applications for low BOD estimation. Four main methods to measure BOD using a biosensor are described: microbial fuel cells, optical methods, oxygen electrode based methods and mediator-based methods. Each of them is based on different principles, thus a different approach is required to improve the limit of detection. A proper choice of microorganisms used in the biosensor construction and/or sample pre-treatment processes is also essential to improve the BOD lower detection limit.

Opis:
The subject of the article is a problem of the Likert’s scale validity as a method of measurement. The author on the basis of empirical findings discusses the issue of prognostic credibility of results while measuring the attitudes applying the Likert’s method. The basic question concerns the agreement of the prognosis that bases on the attitudes’ measurement data, with the actual bahavior. Six scales characterizing the different aspects of attitudes toward work conditions have been employed in the investigations. Subsequently, the findings have been compared to the actual workers’ efficiency. The result allows for an assumption, that utility of a technique considered as the prognostic tool is very limited. In the majority of cases, the results of measurement differed significantly from the data relating to the actual behavior. Almost satisfactory agreement has been reached in case of one scale only. This testifies inaccuracy and at the same time, unrealiability of measurement with that metod and requires caution in employing it as the instrument of prediction.

Opis:
Utrzymanie maszyn i urządzeń w ciągłej pracy jest ważnym kryterium sukcesu przedsiębiorstw produkcyjnych. W przypadku, kiedy z różnych względów nie ma dostępu do dokumentacji technicznej poszczególnych podzespołów lub nie ma możliwości nabycia części zamiennych, dużym wyzwaniem staje się skrócenie do minimum przerw w produkcji spowodowanych awariami. Stosując techniki inżynierii odwrotnej oraz szybkiego wytwarzania na podstawie zużytego lub uszkodzonego elementu można w krótkim czasie wytworzyć jego funkcjonalny odpowiednik. W pracy przedstawiono metodykę pomiaru, odtworzenia dokumentacji trójwymiarowej oraz wytworzenia prototypu funkcjonalnego koła zębatego przenoszącego napęd z silnika w urządzeniu poligraficznym. Dokonano porównania użyteczności części wykonanych z zastosowaniem dwóch technik: kształtowania przyrostowego uplastycznionym tworzywem oraz odlewania próżniowego w formach silikonowych.
Keeping machines and devices in constant operation is an important criterion of success of manufacturing companies. In case when for some reason there is no access to technical documentation of particular sub-assemblies or there is no possibility of purchasing the spare parts, reduction of unwanted pauses in production caused by machine malfunction becomes a huge challenge. Application of reverse engineering and Rapid Manufacturing techniques allows to produce a functional replacement for the worn or destroyed part in a relatively short time. The paper presentsmethodology of measurement, re-creation of 3D documentation and manufacturing of a functional prototype of a helical gear for power transmission from electrical engine in a typographic device. A comparison of usability of parts manufactured using two technologies was prepared. The first technology was Fused Deposition Modeling – one of additive manufacturing technologies and the second technology was Vacuum Casting.
