Abstract:
This master thesis is focused on a research in the field of 3D printing technology. During the research a particular technology, being regularly applied by the RepRap printers, is described. Mentioned technology is tested on a Rebel II printer model. The findings are applied to the dual 3D extruder design project. This dual 3D extruder is designed and made in two basic options, where the first option discovers the shortcomings and the second option is modified and tested. In the following step, assessment of applicability, functionality, as well as economic analysis of production of this dual 3D extruder is made.

Abstract:
This diploma thesis deals with a design and manufacture of an active print head used for 3D printing of concrete mixtures. The aim is to ensure functional parameters of the print head at a minimal mass. Extrusion of the material from the print head is ensured by a screw conveyor, shaping of the material is carry out by a rotatably mounted nozzle provided with trowels. The dimensioning of the main elements of the print head is based on the parameters measured during tests with the older version of the print head and on the FEM analysis. The print head was manufactured and is able to extrude concrete mixture with an admixture of aggregate (fraction 4–8 mm) at a rate of 0,5–2 m3•h-1. The weight of the print head is 16.4 kg, which is 30 percent less than an older print head weighed. The manufactured print head was tested during the printing of a real object and met all the required parameters. The print head is ready for implementation in a machine providing large-scale printing of parts in the construction industry.

Abstract:
This thesis deals with improvement of 3D-manipulator which is currently used for 3D printing. The improvement involves adding a new printer head which will be able to acquire various colors by mixing up to three materials. Furthermore, device is extended with milling as a finishing process responsible for better surface quality of printed object.

Abstract:
The aim of the work is to design and manufacture a mechanism for setting up and clamping the replaceable head of a 3D FDM printer. The first part of the thesis deals with 3D printing in general, the second part describes the FDM method. Part three is devoted to the selection and construction of a suitable 3D printer, the fourth part to the actual design of the head attachment. In the fifth part, a technical and economic evaluation is carried out.

Abstract:
The diploma thesis is focused on waterjet technology, dimensional and shape accuracy of manufactured parts. In the theoretical section, the principle of technlogy and its use in engineering industry at the present time, are described. Moreover, the theoretical section includes discription of every single parts of the machine of waterjet cutting, that are nowadays used. The biggest part of diploma thesis focuses on 3D cutting technology and on attachments for elimination of undercutting. Practical section focuses on dimensional and shape accuracy of manufactured parts manufactured by waterjet technology that makes use of 3D head and different cutting speed. The practical section also includes operating and maintenance cost of the machine. In terms of maintenance, real service life of components is compared there with a lifespan declarated by machine producer.

Abstract:
In this diploma thesis we are discussing about using 3D bioprinting in tissue engineering. We are discribing using biomaterials for construction scaffolder and aplication stem cells in 3D bioprinting. Last section of theoretical part deals with very often used techniques of 3D bioprinting and we are focused on extrusion technique. In the practical part we propose a method for print vasculars structures. We realized prototype of print head, her design and 3D printing of individual parts. To mechanical part we create a control system for printing control. At the end we visualize the organization of the cells using program modules.

Abstract:
With the development of posibilities of image processing, stereoscopy, prices of web cameras and power of computers an opportunity to multiply an experience with working with 3D programs showed. From the picture from webcamera an estimation of a pose of user's head can be made. According to this pose a view on 3D scene can be changed. Then, when user moves his head, he will have a feeling as if monitor was a window through which one can see the scene behind. With the system which is the result of this project it will be possible to easily and cheaply add this kind of behaviour to any 3D application.

Abstract:
The master thesis deals with design of multi material FDM 3D printer. In the first part, current market situation and possible principles of multi material printing are described. Possible variants of individual construction nodes are described in the next part and then the selected variant is processed into a design solution. The benefit of this thesis is a proposal of solution for the automatic printing head exchange, which is practically not concerned by printer manufacturers.
