Various types of 3D scanners are used for digitalization objects (products, space). These mostly different optic or laser scanners. The presented article deals with the comparison Steinbichler Comet L3D optical scanner and Creaform EXAscan scanner. Determination parameters both is necessary if we need measure on obtained data not only use scanned shape. To make this comparison, a specimen was designed that satisfies scanning criteria using two scanners; i.e. it does contain complicated...
This contribution is focused on the influence of build orientation hardness materials sintered using direct metal laser sintering (DMLS) technology. It builds current research works that has monitored a fatigue life, mechanical properties, roughness after machining, etc. In mentioned work, slight above properties was shown. The measured Ti6Al4V alloy which made powder by DMLS individual were at different powers, then annealed to remove internal stresses. Part experiment examined...
Abstract In this study, the effect of powder spreading direction was investigated on selectively laser-melted specimens. The results showed that metallurgical properties specimens varied during fabrication with respect to their position build tray. density, porosity, and tensile Co–Cr–W–Mo alloy were cuboid fabricated at different locations. Two significant positions tray selected along direction. One set located near start line spreading, other end building main role in consequences...
Primary malignant or metastatic sternal tumors are uncommon. A subtotal total sternectomy can offer a radical form of treatment. The issue is to restore the structural integrity chest wall. We report implantation an individualized 3D–printed titanium sternum in patient with tumor. believe that tridimensional print technologies may also change strategy wall reconstruction.
Background/Objectives: Cranial reconstruction (cranioplasty) is a surgical procedure performed to restore skull function and aesthetics following trauma, oncological conditions, or congenital defects. Magnetic resonance imaging (MRI) commonly used for the postoperative monitoring diagnosis of patients with cranial implants. However, MRI artifacts caused by these implants can compromise accuracy diagnostic precision. This study aims evaluate extent titanium polyether ether ketone (PEEK)...
Frequent lower limb amputations caused by the growing incidence of vascular diseases and traumatic injuries currently represent a significant global problem. A properly constructed adjusted prosthetic device is key to reintegration these patients into their family, social, working environments. The main objective submitted article provide clear summary principles regarding prosthesis construction, highlight fundamental rules be applied assembly in stand, static dynamic assessment prosthesis....
One of the blends that is usable for 3D printing while not being toxic to cell cultures lactic acid (PLA)/polyhydroxybutyrate (PHB)/thermoplastic starch (TPS) blend. The addition plasticizers can change rate biodegradation and biological behavior material. In order evaluate potential PLA/PHB/TPS material in combination with additives (plasticizers: acetyl tributyl citrate (ATBC) oligomeric (OLA)), use field biomedical tissue engineering, we performed a comprehensive vitro characterization...
Few examples of technical and biomedical applications bistable magnetic microwires are shown.Particularly, application in civil engineering shown for sensing the mechanical stress concrete, steel structure or cable by simple gluing it on surface studied structure.On other hand, stress, temperature, position inside human animal body shown.Experiments with pig intestine cells points to biocompatibility glass coated microwires.
BACKGROUND The laboratory rat is one of the most popular experimental models for surgery liver. objective this study was to investigate morphometric parameters, physiological data, differences in configuration liver lobes, biliary system, and vasculature (arteries, veins, lymphatic vessels) rats. In addition, supports anatomic literature identified similarities with human other mammals. MATERIAL AND METHODS Forty rats were dissected prepare corrosion casts vascular system specimens (n=20),...
In the automotive industry, 3D laser scanning is most frequently used method to check geometry of shape and dimensions a body in individual stages production, where scanned model compared computer model. This procedure identifies excessive deformations around roof antenna an SUV. The manufacturer assumed that these occurred during assembly process. An analysis possible causes deformation occurrence was performed based on comparison results obtained by numerical experimental modelling....
Genetic algorithms are a robust method for solution of wide variety optimization problems. It explores big space design variables in order to find the best solution. From point view user, algorithm requires encoding into form strings and procedure uses them optimization. Here, structural engineer, it is crucial objective function including constraints task also avoid critical states during responses. This paper presents use genetic solving truss structures. The approach shown on three cases
This work is devoted to the research of porous titanium alloy structures suitable for use in biomedical applications. Mechanical properties were examined on six series samples with different and porosity via static compressive test identify type structure elimination “stress shielding” effect. In addition, high desirable due overgrowth bone tissue into internal implant. The made Ti6Al4V by using selective laser melting (SLM) additive manufacturing. differ from each other pore size (200, 400,...
Biopolymers have been the most frequently studied class of materials due to their biodegradability, renewability, and sustainability. The main aim presented study was evaluate degradability polymer material blend which immersed in different solutions. present included production three mixtures polylactic acid polyhydroxybutyrate, each with a content triacetin, used as plasticiser. Applying 3D printing technology, two types cylindrical specimen were produced, i.e., solid porous specimen,...
The paper deals with the problem of a biomechanical solution for human locomotion after amputation lower limb. With an inappropriately designed transtibial prostheses socket, interaction between socket and stump occurs, leading to increased friction subsequent surface damage soft tissue. In individual types prostheses, locations are defined which can be loaded cannot loaded. On basis study anterior side stump, three loadable two non-loadable areas were monitored using TACTILUS tactile...
The present paper discusses a new approach for the experimental determination of modal parameters (resonant frequencies, shapes and damping coefficients) based on measured displacement values, using non-contact optical method digital image correlation (DIC). output is newly developed application module that, three-dimensional matrix from measurement results, can construct frequency response function (FRF) purpose operational analysis. From this function, interest are able to be determined....
