3D Lattice Structures for Application in Selective Laser Melting technology
Červinek, Ondřej ; Škaroupka, David (referee) ; Vrána, Radek (advisor)
Additive technologies allow manufacturing of components with very complex shapes which are difficult to manufacture with conventional technologies. Among these technologies belongs the Selective Laser Melting (SLM). Suitable applications of SLM include manufacturing of light-weight 3D structures like lattice structure or an organic geometry called gyroid. This bachelor thesis is focused on creation of models of gyroid structure and its application to parts followed by manufacturing with SLM. Series of models were made with mathematical software. Implicitly defined equation were used for better geometry coordination of created models. Options utilization and manufacturability of gyroid structures were tested within application into turbocharger impeller. At the end of this thesis was successfully manufactured the impeller including two types of gyroid structure (single-gyroid and double-gyroid)
Research on process parameters for producing of a structured material made by Selective Laser Melting technology
Richter, Vladislav ; Koutný, Daniel (referee) ; Vrána, Radek (advisor)
Selective laser melting (SLM) is one of additive technologies which allows manufacturing of components with very complex shape. One of the examples are porous lattice structures which are used in cosmonautics or medicine due to its good mechanical properties and low weight. In this work the influence of processing conditions (laser power and laser scanning speed) on material properties and geometry of as-fabricated trusses is investigated. Wide range of laser powers (100–400 W) and laser scanning speeds (1000–10000 mm/s) were used to determine optimum process parameters. Truss size, morphology and internal porosity was investigated using optical 3D scanner and X-ray micro computer tomography (mCT). Based on executed measurements optimum processing conditions were determined to be 350 W and 3000 mm/s. It is possible to manufacture faster geometrically more precise structures with equal internal porosity due to optimization.
Analysis of SLM production accuracy of sipes for tire molds
Tomeš, Jan ; Rapant, Martin (referee) ; Koutný, Daniel (advisor)
The first part of the diploma thesis is focused on the analysis and evaluation of the current production of sipes by two SLM devices PXL and M2 Cusing, produced by Phenix Systems and Concept Laser companies. The samples of both machines went through the same manufacturing process and the same process of measurement and evaluation, in order to carry out comparison between individual machines. Geometric accuracy, surface roughness, mechanical properties, and material structure of the samples have been compared. For the sipes it was necessary to create a digital evaluation methodology of geometry. In the second part of the thesis, process parameters are selected on the basis of research and further their influence on surface roughness of manufactured sipes is analyzed.
Biomechanical research study of skull plates and implants
Vystrk, Tomáš ; Valášek, Jiří (referee) ; Marcián, Petr (advisor)
Cranial implants along with fixators are used to restore the function of the damaged area of the human skull, where due to disease or injury the defect was created. When assessing the suitability of the implant and fixators the mechanical properties are significant. With this the material and shape of implant and fixators are related. The implant must be suitable with human bone tissue and also be able to withstand long-term loading. This paper summarizes the present knowledge regarding the design, manufacture and application of cranial implants. Next the stress-strain analysis of the loaded scull with irregular shaped defect, placed implant and fixation system is provided.
The Use of Additive Technology for Manufacturing Components of the Sample
Vrbická, Eliška ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Thesis deals with the use of additive manufacturing technologies for the production of sample components. These are mainly using method Fused Deposition Modeling (FDM). The production was used to 3D printer for based on this principle. Manufactured subject has own design of pendant, this pendant has shape of blooming flower with leaf. The model was created in SolidWokrs 2013. This model is further elaborated in the program CatalystEX. Thus originated data for the printer Dimension uPrint. Once printing is complete and upon dissolution the of aid were removed imperfections printing. Thus-to-terminated object can be used as a garnish.

Manufacturing of Components Using Rapid Prototyping
Peňáz, Jan ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with solution of manufacturing prototype using three technologies. Two of them are additive technologies using principles of Laminated object manufacturing and Fused deposition modelling. The third technology was milling. Model of reversible turbine was used as a base for manufacturing. CAD system SolidWorks was used for the model creation, where output formats were SLDPRT and STL. For error check of STL data software MiniMagics was used. For preparation of 3D printing data softwares SD View and Catalyst EX were used. CAM system SolidCAM was used for creation of machining strategy. Devices used for manufacturing of prototypes were 3D printer Solido SD 300 Pro, 3D printer Stratasys uPrint and 5axis mill Hermle C20U. Print on 3D printer Stratasys uPrint the most advantageous technology for manufacturing one prototype.
