Wavefront sensor
Škaroupka, David ; Jákl, Petr (referee) ; Dostál, Zbyněk (advisor)
When the light passes through optical elements it can cause deformation of wavefront light due to the damage of materials and optical aberrations. The deformation leads to unprecise imaging and deformation of an image. The diploma work mentions wavefront sensing techniques which are important for determination inappropriate errors of optical elements and the specification of their properties. The purpose of the master's thesis is to suggest and investigate wavefront sensing methods after the light passes through the optical element while using the digital micromirror device. The work deals with the topic of wavefront aberrations and geometric optical defects of optical elements. Different kinds of commercial products determined for wavefront sensing are described too.

Design of the product for additive manufacturing
Ritterová, Diana ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
The thesis deals with the design of an orthopedic insole with emphasis on breathability and support of a longitudial arch. The insole can be manufactured by using 3D printing technology FFF from a flexible plastic TPU filament. The shape of the insole is based on the contour of a foot. The inner structure was designed in the Grasshopper plug-in and then added to the shape of the insole in Rhinoceros.
Redesign of the chip reader
Kusyn, Martin ; Rubínová, Dana (referee) ; Škaroupka, David (advisor)
The bachelor thesis is focused on redesign of a microchip reader for 3D printer filament cartridges. The project deals with current market analysis, as well as analysis of previous cover of the device, application of basic technical and ergonomic parameters, description of proposed solution and its implementation onto current hardware. Emphasis was placed upon ergonomics of handling, reader-cartridge interaction, effective usage of internal space, positions of internal components and application of additive manufacturing guidelines for the manufacturing processes of the cover. Manufacture, fitting and testing of a prototype for the new cover for the microchip reader are also part of this project.
Design of a porcelain set for additive manufacturing
Vítek, Jan ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
This bachelor thesis deals with the design of a set of porcelain coffee cups. The principles of parameterization are used in the design, as well as an innovative way of creating decor using generative algorithms. The thesis examines the possibility of using additive technologies in the production of porcelain products, both in the production of molds and in the direct production by SLA technology. It also includes the development of material for 3D printing from porcelain and finding suitable process parameters for printing.
Comparison of tensile properties of polymeric samples produced by extrusion based 3D printing
Krajcar, Ivo ; Vespalec, Arnošt (referee) ; Škaroupka, David (advisor)
The subject of this work is a summary of the contemporary knowledge about 3D printing and mechanical properties of a prototype manufactured this way. Main goal is to compare the frequently used FDM method with the innovative APF method of 3D printing from the Arburg company. ASA and CPE materials were chosen for researching this method. On these materials, tensile strength was measured. Aditionally, for comparison between the two methods, referential samples manufactured by injection moulding were made. A percentual difference in strength of each sample was compared against these. 60 samples in total were made for this comparison. After evaluation of the results, it was found that in the tensile strength the samples made by the APF method are approximately 30 % less strong than the referential sample. The samples made by the FDM method are approximately of the same strength as the referential sample.
Construction of the stand for the filaments on spools
Bezděk, Petr ; Dočkal, Kryštof (referee) ; Škaroupka, David (advisor)
The aim of this bachelor thesis is to develop a stand for filament spools with minimal unwinding resistance, which eliminates stitching of filament and calculates the amount of unwound material. The stand is designed for a spool filament in the weight range of 250 g to 2.5 kg. Furthermore, the goal is to make the stand universal and usable for various 3D printers. The problem is solved by selecting the most appropriate concept for the problem based on the applicable concept analysis. The work contains an overview of the essential facts concerning stands, unwinding and 3D printing. Subsequently, the key issues are analysed on the basis of balancing the benefits of the possible variants of the concept. The chosen concept is solved in structural parts, which ultimately form a functional unit and a completed product. The result is a complete stand design in the form of written work, production documentation and manufactured product. The stand function has been verified by testing. The work is beneficial in terms of expanding awareness of rack issues, identifying 3D printing problems associated with the spool stand, designing and finished products for use in printing. The design is entirely designed to produce only one piece.
Pneumobile car-body design for robotic fabrication
Vevera, Tomáš ; Nevřela, Petr (referee) ; Škaroupka, David (advisor)
This thesis solves design of the pneumobile bodywork designated for robotic manufacturing using curved folding method. The thesis evaluates possibilities of this technology and issue of specific behaviour of CCF geometries. With intention to simplify and speedup the proces of designing, the suggestion of software tool for CCF geometry simulation is proposed. Obtained pieces of knowledge are being used in creating the prototype of designed solution using curved folding.
Design of the 3D printer for technology Contour Crafting
Anderle, Peter ; Chorý, Tomáš (referee) ; Škaroupka, David (advisor)
The subject of this bachelor thesis is the design of the spatially adaptable 3D printer for Contour Crafting. Aiming to apply megascale aditive technology in a field of construction industry.
Styling of the passenger car Proton Prevé
Burjeta, Josef ; Karásek, David (referee) ; Škaroupka, David (advisor)
The thesis is focused on styling a real passenger car Proton Prevé with regard to the quality of surface modelling using computer software Autodesk Alias. The stylistic adjustments were made on basis of the background research and poll focused on the target group. Selected body parts have been modified according to the desired sport character of the car and the current vehicle’s appearance. The result of the work is a surface model, which was created using A-Class modelling methods under the direction of Evektor company. The benefit of the thesis is facelift of an existing car with consideration of the current market situation and customer requirements.
