Application of Rapid prototyping methods for development of new product
Rozinek, Josef ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
Target of this bachelor’s thesis is to describe application of Rapid Prototyping methods for development of a new product. First it describes principles used by machines for Rapid Prototyping with the overview of selected manufacturers of specific devices. Further it contains certain examples of industrial application. Thesis is concerned about development of a new product using conventional methods and Rapid Prototyping methods with the analysis of the differences and advantages of each method. It describes an issue of design of a new product from the sketch phase to the prototype production phase. As an example of industrial application there is described a Narex angle grinder inovation process.

Analysis of Dimensional Accuracy and Mechanical Properties of Plastic Components Made by 3D Printing
Horák, Ondřej ; Joska, Zdeněk (referee) ; Sedlák, Josef (advisor)
The Master's thesis deals with the determination of mechanical properties of materials used for 3D printing by ALPS ELECTRIC CZECH, s.r.o. (PETG, PLA, ABS, PLA ESD), extended of new materials (ASA, PC / ABS). The prepared test samples, produced by 3D printing technology Fused Deposition Modeling, were analyzed using mechanical tests (tensile test and two hardness tests), surface roughness and dimensional accuracy. Statistical evaluation was performed for individual materials of selected parameters (tensile strength, modulus of elasticity in tension, elongation, Shore hardness, hardness of ball indentation). The conclusion of the thesis is devoted to the comparison of materials by selected parameters and production costs. The additive material PLA Filament Plasty Mladeč proved to be the best with its properties and the second lowest price.

Application of Modern Technologies for a Design of Disc Coupling Production
Varhaníková, Alžbeta ; Varhaník, Matúš (referee) ; Sedlák, Josef (advisor)
The bachelor thesis deals with the design of disc coupling and its production by using 3D printing technology. Model of disc coupling and this thesis are supposed to serve as teaching equipment for students at Secondary vocational schools. The theory section contains the essay of shaft couplings with a detailed description of disc coupling, characteristic of individual methods of Rapid Prototyping technology and materials suitable for 3D printing. The experimental section is dedicated to the calculation and construction design of disc coupling and its production using the Fused Deposition Modeling method. The thesis also contains a description of post-production processing and assembly. The attachments of the thesis consist of assembly mechanical drawing and production mechanical drawing of drive disc.

Mechanical properties of polymers produced by 3D printing technology
Král, Filip ; Moravčík, Igor (referee) ; Válka, Libor (advisor)
The thesis deals with the dependence of mechanical characteristics on the anisotropy of polymers Nylon 12 and Ultem 9085 made by a 3D printing technology Fused Deposition Modeling (FDM). The evaluation of the material characteristics was performed on the basis of tensile and non-instrumental impact tests. It was proven that the material characteristics are strongly dependent on anisotropy, i.e. on layer thickness and raster angle for both types of polymers.

Utilization of the modern method for a production of the prototype of the hair dryer handle
Vrána, Radek ; Slaný, Martin (referee) ; Sedlák, Josef (advisor)
Aim of this bachelor work is to design and produce two-part universal holder of ETA hair dryers. Holder is designed in 3D CAD system Autodesk Inventor and is produced by Rapid Prototyping technology using Fused Deposition method. From existing Fused Deposition Modeling prototype of bigger visual part is made silicon mold and cast from resin. There is evaluation of both methods considering technical-economical aspects in the end of my work. Process of design and production using both methods is documented and described. My work includes history of ETA, a.s. company, characteristics of Fused Deposition Modeling method and technology of casting to silicon mold. Prototypes will be used for further development of holders for ETA´s hair dryers.

Usage of Modern Technologies for the Design of the Production of Push up Stands
Remer, Tomáš ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
This bachelor thesis is focused on the design of the design of push up stands, which are made using the additive Rapid Prototyping technology. The manual beam design is developed in CAD systems, specifically in the Autodesk Inventor parameter set. The model of these beams is made on Fortus 450 mc, which uses Fused Deposition Modeling. The thesis also includes the characteristics of Rapid Prototyping, along with the evaluation of the most used materials and methods. The end of the thesis is completed by the technical-economical evaluation of push up stands, including comparison of the costs of implementation with other organizations.
