AB  - The utilization of biomaterials with mycelia as a stabilizing agent is gaining popularity in the fields of construction and architecture, offering a sustainable solution aligned with the principles of the circular economy. Interdisciplinary research involving biologists, technologists, and engineers is necessary to advance this field where science, art and design converge. These biomaterials contribute to energy reduction and cost-effectiveness, utilizing readily available and recyclable raw materials. Mycelium-based blocks have shown to be more affordable than traditional cement and gypsum blocks while significantly reducing CO2 emissions. The mycelium network, formed by hyphae, can be cultivated into a solid material, providing a defined technological process. This study focusses on performing 3-point bending testing on moulded specimens using additive technology PLA material, following the ASTM D1037 standard. After the growth of mycelium and the formation of the test tube-shaped structure, the samples are dried and characterized to enchance their mechanical characteristics.

AB  - The manufacturing and application of biocomposites are remarkable achievements in replacing conventional non-biodegradable materials. In general, biocomposites are made up of biopolymers and bio-based reinforcing agents. Biofibres are also the main constituents of biocomposites, which are generated from biological entities such as crop fibres (cotton, flax, mycelium of fungi, hemp), recycled wood, wastepaper, agro-based by-products or regenerated cellulose fibre. In this paper, a mould intended for biocomposites based on mycelium and an adequate substrate is tested. The primary purpose of the mould is to bring the loose natural material into a solid preparation following the standards ASTM D7250 and ASTM D1037, which include testing the technologically prepared and hardened sample for tensile and pressure. Development and moulding of biocomposite are the technological processes of drying after sowing mycelium so that a variant of the mould with a perforated upper part was used to harden the samples thoroughly. In the mould, realization is used PLA thermoplastic filaments. Mould was made as an assembly of two parts, and its shape is like a dog bone, according to the mentioned standards. This polymer enclosure is helpful for other biocomposite structures (a mixture of different fungi species and adequate substrates).
AB  - Proizvodnja i primena biokompozita je značajno doprinela smanjenju upotrebe nebiorazgradivih materijala. U opštem smislu, biokompoziti se sastoje od biorazgradivih prirodnih polimera (biopolimera) i ojačavajuće faze-biovlakana. Biovlakna su glavni sastojci ovih materijala i mogu biti različitog prirodnog porekla (pamuk, lan, konoplja, micelije gljiva, reciklirano drvo, agroproizvodi ili regenerisana celulozna vlakna). U ovom radu, testiran je i razvijen kalup za biokompozite na bazi micelijuma i odgovarajućeg supstrata (pšenične slame). Osnovna namena kalupa je priprema i očvršćavanje bio materijala da bi bilo omugućeno ispitivanje u skladu sa standardima ASTM D7250 i ASTM D1037, koji su namenjeni ispitivanju uzoraka na istezanje i pritisak. Izrada i 
oblikovanje biokompozita predstavljaju tehnološke postupke koji se sprovode u cilju sušenja i smanjenja procenta vlage nakon zasejavanja, pri čemu je gornji deo perforiran zbog isparavanja i što boljeg očvršćavanja uzoraka. Za proizvodnju kalupa upotrebljen je PLA termoplastični filament. 
Kalup je izrađen kao dvodelni sklop, oblika “dog bone” u skladu sa pomenutim standardima.

AB  - Reverse engineering (RE) aims to design a new replacement part based on
the existing part. The goal is to perform a quality reproduction of the
physical part with the best possible mechanical characteristics aiming to
find optimal solutions regarding the shape and dimensions of the part. The
procedure is implemented through a series of steps: creating a digital 3D
model, improving model parameters, and realizing products using additive
technologies. In this paper, a review and implementation of the funda–
mental methodologies of RE were carried out on the example of a damaged
protective cover with an unknown geometry and material essential for the
function of a discontinued device with no technical documentation and
spare parts. An optical scanning method, 3D CAD, FEA, and additive
manufacturing were used to realize the reproduced part. It was shown that
by utilizing RE the lifecycle of the device could be significantly extended
with minimal cost.

AB  - Composite materials are a combination of two or more materials at the macroscopic level. They have better characteristics than individual components. By combining different types of mountings and matrices, new advanced materials can be obtained to improve performance. In complement to standard structures (carbon-epoxy, glass-epoxy), increasing importance is given to biodegradable materials. Most often, materials with a vegetative part of fungi (mycelium-mesh structure of hyphae) are used, which are increasingly used to realise biocomposites with unique processing technology. These composites have relatively good mechanical properties and are environmentally friendly because they are biodegradable. Today, biocomposites are used in packaging production, fashion, and construction, and the emphasis is on the food industry. This paper presents the making mould technology to set the biocomposite structure and test their mechanical characteristics. The mould for pressing biomaterial connected with mycelium is made of two parts. The primary purpose of the mould is to bring the loose natural material into a solid preparation following the standards ASTM D7250 and ASTM C393, which include testing the technologically prepared and hardened sample for bending and shearing. The testing included two phases. In the first, hardened samples without moisture were tested. The second involved the technological process of drying after sowing mycelium so that a variant of the mould with a perforated bottom was used to harden the samples thoroughly. A comparative analysis of the results in both phases was performed, which was a further guideline in examining the improvement of composite characteristics.

AB  - This paper presents the 3D printing technology for various textile materials. The application of this technology is vital in manufacturing various clothing items, primarily for specific purposes: hikers, firefighters, soldiers, and athletes. The installation of sensors, life function parameters monitoring and the usage of the new materials are the basis for the future development of the textile industry. Today, thermoplastic and textile materials are increasingly used in practice. Polylactic Acid (PLA) thermoplastic materials were used in the paper - in spool, Polyvinyl Chloride (PVC) and Nylon (in strips); while from textile materials, polyester, viscose and silk in the form of finished fabrics were considered. The technology of preparation of textile fibres for 3D printing using laser is shown. This technology makes it easier to combine textiles and molten filament. The pros and cons of joining different materials are discussed. Further research would go in the direction of making constructive solutions and testing the mechanical properties of various textile-polymer composites.

AB  - The purpose of this paper is to explore and define an adequate numerical
setting for the computation of aerodynamic performances of wind turbines of
various shapes and sizes, which offers the possibility of choosing a suitable
approach of minimal complexity for the future research. Here, mechanical
power, thrust, power coefficient, thrust coefficient, pressure coefficient,
pressure distribution along the blade, relative velocity contoure at different
wind speeds and streamlines were considered by two different methods: the
blade element momentum (BEM) and computational fluid dynamics (CFD),
within which three different turbulence models were analyzed. The
estimation of the mentioned aerodynamic performances was carried out on
two different wind turbine blades. The obtained solutions were compared
with the experimental and nominal (up-scaled) values, available in the
literature. Although the flow was considered as steady, a satisfactory
correlation between numerical and experimental results was achieved. The
comparison between results also showed, the significance of selection,
regarding the complexity and geometry of the analyzed wind turbine blade,
the most appropriate numerical approach for computation of aerodynamic
performances.

AB  - This paper presents the failure analysis results of the helicopter skid landing gear. The helicopter skid landing gear fractured while the helicopter was on the ground at the airport. The aft cross tube of the landing gear assembly was found fractured into two pieces. Observation of crack propagation area at low magnification revealed numerous secondary cracks, inner surface irregularities while fracture surface indicated fatigue process. Macro-fractographic analysis of the fracture surface disclosed features that gave additional indication of fatigue. Examination of mating fracture surfaces under scanning electron microscope (SEM) detected the existence of irregularities in the material. Chemical analysis showed the aft cross tube is made of high-strength aluminum alloy. The stress analysis of skid landing gear, using the finite element method (FEM), has identified the stress-deformation condition of the helicopter landing gear with a detail insight of the stress state in the vicinity of the crack origin. The stress value, in case of maximal takeoff weight, was very high in the crack initiation zone. The results indicate the superposition of manufacturing-in, designing-in as well as operating in defects which led to total failure of the helicopter skid landing gear aft cross tube.

energy sources. At higher altitudes, we have better wind energy utilization higher speed and
their conversion are achieved in the best possible use of wind turbines. The development of new technologies
opens space for a new generation of wind turbines with a 20MW rated power. In recent
years, various feasibility studies have shown that wind turbines with large rotor diameter and high
towers give positive shifts in the analysis of structural and aerodynamic parameters, with a focus on
reducing overall mass and damping vibrations due to the use of new materials. In this paper, the
evolution of high power wind turbines and an overview of the technological development of the basic

AB  - Veoma veliki porast upotrebe 3D štampe u poslednje dve decenije posledica je niza benefita koje
ova proizvodna tehnologija nudi. U ovom radu analizirano je odstupanje geometrije štampanog modela u
odnosu na CAD model. Izrada eksperimentalnog modela izvršena je metodom fuzionog taloženja filamenta
(FDM) pri čemu je korišćen akrilonitril butadien stirol (ABS) materijal. Pokazano je kako se sa brojem
iteracija odstupanje geometrije 3D štampanih modela u odnosu na CAD model smanjuje. U zaključku je dat
pregled celokupnog procesa i preporuke u pogledu ograničenja upotrebe ove metode.
AB  - Large increase in the use of 3D printing or rapid prototyping in the last two decades is due to the many
benefits that this manufacturing technology offers. In this article geometry accuracy of 3D printed parts is analyzed.
For printing of the analyzed model Fused Deposition Modeling (FDM) method was employed. ABS material was used
to create the specimens. The measurement results have shown that the dimensional accuracy of printed parts increases
with the number of iterations. The overview of analyze and some recommendations in the sense of limitation in the
application of this method are given as a conclusion of this paper.

ova proizvodna tehnologija nudi. U ovom radu analizirano je odstupanje geometrije štampanog modela u
odnosu na CAD model. Izrada eksperimentalnog modela izvršena je metodom fuzionog taloženja filamenta
(FDM) pri čemu je korišćen akrilonitril butadien stirol (ABS) materijal. Pokazano je kako se sa brojem
iteracija odstupanje geometrije 3D štampanih modela u odnosu na CAD model smanjuje. U zaključku je dat
pregled celokupnog procesa i preporuke u pogledu ograničenja upotrebe ove metode., Large increase in the use of 3D printing or rapid prototyping in the last two decades is due to the many
benefits that this manufacturing technology offers. In this article geometry accuracy of 3D printed parts is analyzed.
For printing of the analyzed model Fused Deposition Modeling (FDM) method was employed. ABS material was used
to create the specimens. The measurement results have shown that the dimensional accuracy of printed parts increases
with the number of iterations. The overview of analyze and some recommendations in the sense of limitation in the
application of this method are given as a conclusion of this paper.",

AB  - Additive manufacturing technology helped many organizations to save
money in the product design process by reducing prototype costs, and also by providing a means for early evaluation and decision making. The idea of this paper is
to design an electronics enclosure for an intelligent industrial pressure transmitter,
using the additive technology. All enclosure elements are made on a 3D printer
WANHAO duplicator i3 plus, using PLA materials. The enclosure realization,
from CAD drawings to the finished model, enables a designer to correct existing errors, or make certain modifications as required by end-users. A process is
described that enables designers to review their decisions at any stage of product
realization, thus providing much more freedom in rapid prototyping. In this example, the advantages and disadvantages of additive manufacturing over conventional
manufacturing are outlined. Some deficiencies have also been observed, such as
mechanical damage to surfaces, burning of surfaces, tearing of prints, and surface
roughness. To mitigate such irregularities, both mechanical and chemical finishing
methods were used. The example confirmed that the finishing methods can affect
the final enclosure dimensions and shape. Further prototype development should
focus more on print quality, which depends on the shape of surfaces, the accuracy
of the geometry, the uniformity of structure and shape, material density, and the
resolution of details.

AB  - Rapid innovations in 3D printing technology have allowed highly complex parts to be manufactured quickly and easily, particularly for prototyping purposes. Fused Deposition Modeling of thermoplastic materials is one of the most commonly used techniques in three-dimensional (3D) printing. The major aim of Fused Deposition Modeling (FDM) is to design and manufacture usable parts for fields such as engineering and medicine. Therefore, it is essential to investigate the mechanical properties of such FDM processed structures. One of the most commonly used materials currently on the market is Polylactic Acid (PLA). The main purpose of this paper is to investigate the effects of aging and heat treatment on the tensile properties of PLA printed test specimens. The tensile properties of parts manufactured by the 3D printer are influenced by various parameters such as extrusion temperature, infill density, building direction, layer height, etc. A total of 96 specimens were built by altering building orientation and layer height to estimate and compare the tensile properties of the printed parts. To investigate the aging effect, 30 of 96 specimens were printed 6 months before the tensile experiment. Half of both aged and new specimens were cured in an oven at 57.5 [˚C] for 3 hours while the other half endured no heat treatment. After the performed measurement, it can be concluded that heat treatment generally improves structural strength of the printed parts, while aging decreases it. However, these effects are highly dependent on the layer thickness and printing quality. The tensile test is conducted according to the ASTM D638 standard. The fractured samples were further characterized using an electron microscope.

AB  - The increasing size of wind turbine blades leads to various flow phenomena which are
influenced by aerodynamic design of blade. Detailed information of flow separation and wake
development are important for wind turbine blade designers to optimize blade design. In order to
obtain detailed information on the flow field, CFD (computational fluid dynamics) modeling is
the topic in many research studies.
In this paper aerodynamic analysis of the reference DTU 10 MW HAWT rotor using finite
volume method was done. Numerical simulations are realized in a commercial software package
ANSYS FLUENT. Flow field is modeled by Reynolds Averaged Navier-Stokes (RANS)
equations using transition SST viscous model. The pressure-based SIMPLEC pressure-velocity
coupling and 2nd order spatial discretization schemes were used for calculation. Obtained
numerical results for mechanical power, power coefficient, thrust, thrust coefficient, pressure
coefficient and relative velocity contours at rated wind speed were considered. The results were
compared with the reference results and conclusions were derived.

AB  - Metal membranes are the thin circular plates. For transducers and pressure transmitters, it is
assumed that the membrane is loaded with uniform load over the entire surface. In case that the membrane is
rigid over the edge, then it is called a diaphragm. In general, the membranes are divided into flat and
corrugated. Corrugated diaphragms can resist much higher pressure than flat diaphragms and they are used
mainly in the low pressure area. In contact with various aggressive fluids, membranes are most commonly
made of high alloy austenitic steel, which have high corrosion resistance, have good spring properties and
they are stable at different temperatures. The deflection analyses of corrugated diaphragms are very important
in sensitivity of transducers/transmitters. The application of corrugated diaphragms gives possibility to control
sensitivity of thin diaphragms by geometrical parameters. In this paper numerical and experimental structural
analysis of a thin corrugated diaphragm 19 mm diameter, with variable material thickness and corrugation
number is presented. Experimental tests are conducted on a corrugated stainless steel (AISI 316) diaphragm.
The measured deflections are compared with numerical results in ANSYS software package. The results
showed small deviations between numerical and experimental data, which is very important for further
diaphragm application of measurement instruments.
