Design of compact MSLA 3D printer
Korábová, Anežka ; Křenek, Ladislav (referee) ; Haltof, Vladimír (advisor)
This bachelor thesis deals with design of compact MSLA 3D printer. Main goal of this thesis is to design MSLA 3D printer with emphasis on print quality and minimal easy maintenance. Design is based on gained knowledge from analyse of current products and their technology. Design takes account of the ergonomic aspects and brings new constructional solutions of inner components. The application of the product is not only for designers and modelers, but also for handymen and 3D print enthusiasts.

Manufacturing of consumer accessories using rapid prototyping technology
Koubek, Michal ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
My bachelor thesis is focused ou the production of applied supplements not commonly available. The applied supplements were modelled by Autodesk Inventor graphic program, transferred to, outcoming format of data and them produced by Rapid Prototyping technology by using fused deposition modelling aditive method. The part of my thesis i salso production of silicon form of chosen part by means of vakuum moulding system. My thesis is finished by technical and economical evaluation comparing the price, for which these supplements can be obtained in the market or produced by means of 3D printed uPrint by using fused deposition modelling method, which is available at Brno Universit of Technology – Faculty of Mechanical Engineering.

Development of process parameters for the stereolithography
Vítek, Jan ; Škaroupka, David (referee) ; Paloušek, David (advisor)
This bachelor thesis deals with the search for optimal process parameters to reach a high strength of the Detax Solflex model material, with the DLP (digital light processing) 3D Solflex 650 printer. In the first part of this thesis the principle of printing using a laser and using a DLP projector and their comparison are presented. Further information about materials and impact of the process parameters on a printing are discussed. Based on a knowledge two assumptions were set: influence of exposure time and influence of layer thickness on strength. Firstly, samples were tested by the hardness Shore D test and the results from the test were compared. New samples for the stress test with the optimal set of parameters given by the previous test were printed and tested. Process parameters influence on strength was determined from the achieved results.

Polymeric metamaterials with advanced mechanical properties
Štaffová, Martina ; Lehocký,, Marian (referee) ; Kotoul, Michal (referee) ; Jančář, Josef (advisor)
Práce se zabývá 3D tištěnými polymerními auxetickými strukturami s důrazem na jejich mechanické vlastnosti. Pro zlepšení mechanických vlastností, zejména poměru schopnosti absorpce energie k hmotnosti při tlakovém zatížení, byly použity různé návrhy auxetických re-entrantních struktur. Struktury byly vytištěny pomocí stereolitografické 3D tiskárny. Byl vyvinut a systematicky demonstrován nový nástroj pro komplexní charakterizaci 3D tištěných těles s využitím komerční fotopolymerizační pryskyřice s volnými radikály. Metoda se opírá o statický a oscilační mechanický test kombinující měření teploty průhybu při zatížení (HDT) s dynamickou mechanickou analýzou (DMA) v jediném testu pro rychlou a spolehlivou charakterizaci parametrů určujících chování fotopolymeru při vytvrzování. Byly zkoumány podmínky tisku a doba vytvrzení, aby byl objasněn jejich vliv na vnitřní napětí v 3D tištěných tělesech. Auxetické struktury byly vytištěny pomocí flexibilní a tuhé pryskyřice a byl zkoumán vliv poréznosti, velikosti buněk a strukturálních gradientů na mechanické vlastnosti. Výsledky byly vyhodnoceny z konstrukčního a materiálového hlediska pro fotopryskyřice nad a pod Tg. Nejlepší účinnost absorbování energie byla zjištěna u biaxiálně orientované struktury s nejvyšší lokální porozitou umístěnou ve středu. Prezentovaná data přispívají k základnímu pochopení účinků designu buněk na deformační odezvu auxetických struktur a mohou pomoct při návrhu nových struktur s lepšími mechanickými vlastnostmi. Výsledky zároveň demonstrují všestrannost 3D tisku při realizaci komplexních, přírodou inspirovaných struktur.

The influence of the parameters of stereolithographic 3D printing on the printing time
Kůst, Martin ; Škaroupka, David (referee) ; Zatočilová, Aneta (advisor)
This paper deals with stereolithographic 3D printing (SLA). It describes both upper and lower lighting design and shows the differences between laser light and DLP (Digital Light Processing) projector. Another part is to find the dependence between the time of exposure and the thickness of the layer also known as material profile on the DETAX, gray. So another work and further experiments can be done using this material. These experiments are performed on Way2production's SolFlex650 SLA printer. For ease of use with this printer, parameters affecting print time have been identified and a model is then found to calculate the total print time.
