AB  - Additive manufacturing (AM) technologies have evolved significantly in recent decades, bringing new trends to production processes. The advantages compared to conventional technologies are numerous: production is simpler and faster, geometry can be adjusted more easily, the quality of finished parts is better, less material is wasted, and costs are lower. Because of the wide range of
possibilities, the different AM processes and the materials that can be used, these technologies have found their place in many industries, with significant application in biomedical field. Flexibility in geometric freedom, in particular, is important for the fabrication of biomedical devices. AM technologies proved that diagnostics is facilitated and improved through the fabrication of customized and in-demand parts, consultation between physicians and patients are supported, and thus the opportunity to develop individualized, patient-specific medicine is provided. This review briefly outlines current applications and AM processes in the biomedical field.

AB  - Since the beginnings of additive manufacturing (AM) in the 1980s, vat polymerization was the first and most intensively developing technology that enabled the production of very precise parts from photosensitive polymer resins. One of the most studied polymer materials is acrylonitrile butadiene styrene (ABS), but mostly in the form of filaments for the FDM (Fused Deposition Modelling) process. The objective of this research was to investigate in detail the mechanical properties of ABS resin specimens fabricated by stereolithography (SLA) and digital light processing (DLP). Specimen geometries were based on standards for tensile, threepoint bending, and compression tests. By combining deformation and mechanical tests with optical microscopic analyses of the morphology and fracture surface structures, as well as Shore A hardness measurements, a deeper insight into the behaviour of commercially available ABS resins was gained.

AB  - Additive manufacturing technologies have developed rapidly in recent decades, pushing
the limits of known manufacturing processes. The need to study the properties of the different
materials used for these processes comprehensively and in detail has become a primary goal in order
to get the best out of the manufacturing itself. The widely used thermoplastic polymer material
acrylonitrile butadiene styrene (ABS) was selected in the form of both filaments and ABS-like resins
to investigate and compare the mechanical properties through a series of different tests. ABS-like
resin material is commercially available, but it is not a sufficiently mechanically studied form of
the material, which leads to the rather limited literature. Considering that ABS resin is a declared
material that behaves like the ABS filament but in a different form, the objective of this study was to
compare these two commercially available materials printed with three different 3D printers, namely
Fused Deposition Modelling (FDM), Stereolithography (SLA) and Digital Light Processing (DLP). A
total of 45 test specimens with geometries and test protocols conforming to the relevant standards
were subjected to a series of tensile, three-point bending and compression tests to determine their
mechanical properties. Characterization also included evaluation of morphology with 2D and 3D
microscopy, dimensional accuracy of 3D scans, and Shore A hardness of each material and 3D printing
process. Tensile testing results have shown that FDM toughness is 40% of the value for DLP. FDM
elongation at break is 37% of DLP, while ultimate tensile stress for SLA is 27% higher than FDM value.
Elastic modulus for FDM and SLA coincide. Flexure testing results indicate that value of DLP flexural
modulus is 54% of the FDM value. SLA strain value is 59% of FDM, and DLP ultimate flexure stress
is 77% of the value for FDM. Compression test results imply that FDM specimens absorb at least
twice as much energy as vat polymerized specimens. Strain at break for SLA is 72% and strain at
ultimate stress is 60% of FDM values. FDM yield stress is 32% higher than DLP value. SLA ultimate
compressive stress is half of FDM, while value for DLP compressive modulus is 69% of the FDM
value. The results obtained are beneficial and give a more comprehensive picture of the behavior of
the ABS polymers used in different forms and different AM processes

AB  - Jedna od najperspektivnijih tehnika za ispitivanje sastava, strukture i svojstava materijala je mikroskopija sondama za skeniranje (SPM), odnosno njene komponente mikroskopija tunelovanjem elektrona (STM) i mikroskopija atomskim silama (AFM). Ovim metodama se rutinski postiže nanometarska i atomska rezolucija. Posebno istaknuta prednost metode je da ne postoje ograničenja u smislu porekla i sastava uzoraka, te je moguće ispitivanje organskih i neorganskih materijala. Ova tehnika se primenjuje u savremenim multidisciplinarnim istraživanjima u oblasti medicine, farmacije, stomatologije, nauke o materijalima, itd, i to za ispitivanje bioloških uzoraka, hemijskih jedinjenja, farmaceutskih proizvoda, veštačkih tkiva, materijala za implantologiju, i svih ostalih materijala čija nanotehnološka svojstva imaju uticaj na primenu u navedenim naučnim oblastima. Međutim, snimci dobijeni pomoću AFM-a su samo aproksimacije površina uzoraka, jer sonde nemaju ni savršenu veličinu ni geometriju, usled čega dolazi do pojave artefakata koji se definišu kao karakteristike koje se pojavljuju na snimku a koje nisu prisutne na ispitivanom uzorku. Ovi efekti izazvani konvolucijom između sonde i uzorka mogu do izvesne mere da budu korigovani matematičkom manipulacijom topografskim podacima. Metodologija koja je u ovom radu korišćena se zasniva na algebri skupova i osnovnim alatima matematičke morfologije. Iskorišćeni su matematički algoritmi za “slepu rekonstrukciju” vrhova sondi, a potom je izvršena dekonvolucija, da bi se otkrili delovi površine uzorka koji u realnosti nisu bili dostupni. Granica realnog vrha sonde se izračunava iz slike pomoću morfoloških ograničenja koja su inherentna u procesu snimanja.

AB  - One of the most perspective available technique for investigation of the composition, structure and properties of materials, is scanning probe microscopy (SPM), respectively its components scanning tunneling microscopy (STM) and atomic force microscopy (AFM). The advantage of the method is that they have no restrictions related to origin and composition of the material, and its possibilities to investigate vide variety of materials. This technique is used in multidisciplinary research in the field of medicine, pharmacy, dentistry, material science, etc., for study of biological samples, chemical compounds, pharmaceutical products, artificial tissues, implantology materials, and all other materials that have nanotechnological impact on application in these scientific fields. However, images obtained by AFM represent only approximation of the sample surfaces. This is because the probes have not perfect size and geometry, which leads to the appearance of artifacts. They are defined as characteristics that appear on the image and are not present on the sample. These effects caused by convolutions between the probe and sample can be corrected to a certain extent by mathematical manipulation of topographic data. The methodology used in this paper is based on algebra of sets, and basic tools of mathematical morphology. Mathematical algorithms for the "blind reconstruction" of the tip were used, and then in order to detect the parts of the sample surface which is not available in real-time scanning deconvolution was applied. The limit of the real probe tip is calculated from the image, using the morphological limitations inherent in the recording process. The result acuired as an image of the reconstructed surface out of the used images, with the reconstruction of the real tip.

abstract = "Jedna od najperspektivnijih tehnika za ispitivanje sastava, strukture i svojstava materijala jeste mikroskopija sondama za skeniranje (SPM), odnosno njene komponente mikroskopija tunelovanjem elektrona (STM) i mikroskopija atomskim silama (AFM). Ovim metodama se rutinski postiže nanometarska i atomska rezolucija. Posebno istaknuta prednost metode je da ne postoje ograničenja u smislu porekla i sastava uzoraka, te je moguće ispitivanje organskih i neorganskih materijala. Ova tehnika se primenjuje u savremenim multidisciplinarnim istraživanjima u oblasti medicine, farmacije, stomatologije, nauke o materijalima, itd., i to za ispitivanje bioloških uzoraka, hemijskih jedinjenja, farmaceutskih proizvoda, veštačkih tkiva, materijala za implantologiju, i svih ostalih materijala čija nanotehnološka svojstva imaju uticaj na primenu u navedenim naučnim oblastima. Međutim, snimci dobijeni pomoću AFM-a samo su aproksimacije površina uzoraka, jer sonde nemaju ni savršenu veličinu ni geometriju, usled čega dolazi do pojave artefakata koji se definišu kao karakteristike koje se pojavljuju na snimku a koje nisu prisutne na ispitivanom uzorku. Ovi efekti izazvani konvolucijom između sonde i uzorka mogu do izvesne mere da budu korigovani matematičkom manipulacijom topografskim podacima. Metodologija koja je u ovom radu korišćena zasniva se na algebri skupova i osnovnim alatima matematičke morfologije. Iskorišćeni su matematički algoritmi za "slepu rekonstrukciju" vrhova sondi, a potom je izvršena dekonvolucija, da bi se otkrili delovi površine uzorka koji u realnosti nisu bili dostupni. Granica realnog vrha sonde izračunava se iz slike pomoću morfoloških ograničenja koja su inherentna u procesu snimanja. Rezultat se dobija u vidu snimka rekonstruisane površine uzorka iz dobijenih snimaka, uz pomoć rekonstrukcije vrha sonde kojom je uzorak sniman. Prikazani rezultati očigledan su dokaz upotrebne vrednosti mikroskopije atomskim silama kao tehnike za snimanja bioloških materijala u nanodimenzionalnom svetu, a primenjeni algoritmi povećavaju upotrebnu vrednost snimaka u smislu boljeg zaključivanja na osnovu preciznijih numeričkih podataka uzetih sa procesuiranih snimaka., One of the most perspective available techniques for investigation of the composition, structure and properties of materials, is scanning probe microscopy (SPM), respectively its components scanning tunneling microscopy (STM) and atomic force microscopy (AFM). This technique is used in multidisciplinary research in the field of medicine, pharmacy, dentistry, material science, etc., for study of biological samples, chemical compounds, pharmaceutical products, artificial tissues, implantology materials, and all other materials that have nanotechnological impact on application in these scientific fields. This is because the probes have not perfect size and geometry, which leads to the appearance of artifacts. They are defined as characteristics that appear on the image and are not present on the sample. These effects caused by convolutions between the probe and sample can be corrected to a certain extent by mathematical manipulation of topographic data. The methodology used in this paper is based on algebra of sets, and basic tools of mathematical morphology. Mathematical algorithms for the "blind reconstruction" of the tip were used, and then in order to detect the parts of the sample surface which is not available in real-time scanning deconvolution was applied. The limit of the real probe tip is calculated from the image, using the morphological limitations inherent in the recording process. The result acuired as an image of the reconstructed surface out of the used images, with the reconstruction of the real tip. The presented results are clear proof of the usability of atomic force microscopy as a technique for imaging of biological materials on nano-level, and the applied algorithms increase the usability of the images in terms of a better conclusion based on precise numerical data taken from the processed images.",

AB  - In this paper, we present the results of fullerene film engraving using a diamond tool. Based on available literature data, to our knowledge the fullerene film machinability is not explored in literature. Therefore, we have investigated wear mechanisms of the engraving process that could be used in micromachining. The engraving process parameters were estimated on the basis of poor quality groove's edge. The flat diamond tip, which remains after wear, has a pitted surface which was observed with a digital optical microscopy and identified using AFM. Soot-like wear debris was observed and spectroscopically analyzed. FTIR spectroscopy results strongly indicate that fullerene C-60 disappears as a molecule and interacts with oxygen, nitrogen and water vapor from the atmosphere. The occurrence of tool wear and wear debris were observed by nondestructive thermography testing. Results confirm that development of high temperature in a cutting zone of 1556 degrees C causes extensive thermo-chemical tool wear.

AB  - In this paper the authors present the results of surface characterisation of a lead telluride alloy conducted by atomic force microscopy and magnetic force microscopy. Relationship between surface morphology, in the range of several nanometres, and the magnetic properties allows precise determination of nanomagnetic particles size with their distribution within a scanned area. This method allows the characterisation of nanoparticles in dimensional and magnetic sense since the paramagnetic and diamagnetic range can be examined.

AB  - Magnetic behavior of C-60 thin films in the Earths magnetic field under polarization light influence is presented. Transformation of magnetic field for two fullerene thin films of different thickness is investigated. Two proton magnetometers were used for these measurements. Samples of 30 nm and 250 nm thickness illustrate a significant change of magnetic field intensity under the influence of polarization light. in range from 3.4 to 12.9 nT, for 200 measurement data per sample.
