MEASUREMENT OF THERMAL SYMMETRY OF THE HUMAN SPINE BY THE USE OF MEDICAL THERMOGRAPHY

The Aim of the study was to identify the temperature symmetry on physiologically healthy dorsal parts of torso. Because of problems with the correct focus on the central values of temperature on the dorsal side of the torso, the methodology of 3D body scanning was included. For the purposes of this study, two databases of 23 thermograms and 23 scans of dorsal trunks were created. The measured value of the average difference was 0.4°C. The 3D human body scanner was used for calculation of the length and size of spinal curvature in the sagittal plane. An important contribution of the study has been to establish a process for obtaining thermograms through the identification of focus area with 3D Body Scanner

Právne a etické aspekty 3D biotlače

Tak ako každá nová revolučná technológia, aj technológia biotlače má okrem množstva prísľubov a výhod aj množstvo výziev, ktoré je potrebné správne pomenovať a venovať im náležitú pozornosť. Cieľom tohto článku bude preto aspoň čiastočne pomenovať vyvstávajúce etické a právne aspekty a výzvy biotlače skúmaním etického a právneho rámca biomedicínskeho výskumu a biotlače v právnom prostredí Slovenskej republiky ako členského štátu Európskej únie, a vysloviť prípadné návrhy ich riešenia

DETERMINATION OF THE GEOMETRICAL AND VISCOELASTIC PROPERTIES OF SCAFFOLDS MADE BY ADDITIVE MANUFACTURING USING BIOPLOTTER

Additive Manufacturing (AM) is a name of a group of technologies that build 3D objects by adding layer-upon-layer of material. There are many technologies, including Rapid Prototyping (RP), Direct Digital Manufacturing (DDM), layered manufacturing and additive fabrication. Many types of materials can be used for AM technology. Biodegradable polymers such as polylactic acid (PLA) and polyhydroxybutyrate (PHB), are currently the subject of intensive research in the field of additive manufacturing and regenerative medicine. A number of biodegradable and bioresorbable materials, as well as scaffold designs, have been experimentally and clinically studied in many research facilities around the world. For effective using of bioprinting technologies in tissue and biomedical engineering, the knowledge of material and technological parameters in the process of printing is necessary. In this study the 3D printer Bioplotter EnvisionTEC (the printer with ability to print different materials from hydrogel to plastic materials) was used. Scaffolds for the purpose of the experiment were prepared via extrusion-based bioprinting. Experimental part of this study was focused on defining the influence of printing parameters and technological pre-processing of the material on quality and mechanical and geometrical properties of printed parts. Testing of printed samples showed high influence of pre-processing of material, mainly drying process, on mechanical and geometric quality of samples. Drying of material before printing process makes the material more stable and allows it to maintain defined material properties for a longer time than non-dried material. Time of heating of the material in printing cartridge has also high impact on material behaviour. Test results showed that if the time of heating of the material in the high temperature cartridge exceeds defined time limit, the material starts to degrade and is no more usable

Dimensional Accuracy and Final Density Measurement of One-, Three-, and Eight-Unit Fixed Dental Frameworks Based on Co-Cr, Manufactured by Using Conventional, Additive and Subtractive Technologies

For the aim of this study, 90 fixed metal frameworks based on Co-Cr were made by using conventional lost vax technique, additive 3D printing done by Selective Laser melting (SLM) technique and subtractive manufacturing using CNC milling. Constructions were produced by the Ceramill Motion 2 milling machine (Amann Girrbach) and Mlab Cusing R 3D printer (GE Additive). Samples were made as one-, three- and eight-unit frameworks based on existing clinical cases. Initial stl. model was built up on a scanned plaster model of three clinical cases by ZirconZahn Modellier software. Evaluation of dimensional accuracy was made by comparison of initial stl. model with a scan of manufactured framework and analyzed by measurement software.  Density measurements were made by helium (He) based gas pycnometry.  Gained data was statistically analyzed by using T-test and F-test for technologies comparison and non-parametric form of ANOVA: Kruskal Wallis was applied in density evaluation of all samples
