Previous issue date: 2016-02-23 / This paper aims to map how 3D printing is already affecting and will affect intellectual
property. In Chapter 1, we trace the historical development of intellectual property as well as
the philosophical justifications for this related to the development of technologies that work
with content (music and movies) such as the internet. Therefore, we make analogies with this
case in order to capture insights that can guide the analysis regarding the relation intellectual
property and 3D printer . Chapter 2 lends itself to analyze the 3D printer and its development
in the market; there are also reflections on the Maker Movement, Open Source Hardware
licenses and the environmental effects of this technology. Chapter 3 analyzes cases that have
already occurred involving 3D printers and intellectual property, analyzing how this technology
further enhances the problem of the performance of intellectual property in the XXI century. / O presente trabalho objetiva mapear de que forma a impressão 3D já afeta e afetará a

Antenas para sistemas RFID impressas em substrato flexível. / Antennas for RFID systems printed on flexible substrate.Valmiro, Robson 12 February 2015 (has links)
Identificação de Dispositivos por Radiofrequência, do inglês, Radio Frequency Identification Device (RFID), é uma tecnologia para identificação, rastreamento e gerenciamento de produtos, animais e até mesmo pessoas sem a necessidade de um campo visual. Com o objetivo de alcançar custos menores e a utilização de processos de fabricação menos agressivo ao meio ambiente, tornou-se importante o desenvolvimento de novos tipos de etiquetas (tags). Em vista disso, a fabricação de antenas impressas compactas usando tinta condutiva, representa uma boa opção. O objetivo dessa pesquisa é o projeto e fabricação de antenas impressas sobre substratos flexíveis utilizando tinta condutiva composta de nanopartículas de prata. O desenvolvimento deste tipo de etiquetas é justificado principalmente pelos seguintes motivos. Primeiro, o processo reduz o uso de agentes químicos comumente empregados na fabricação convencional, levando a uma significativa redução no impacto ambiental. Segundo, a fabricação utilizando substratos como, por exemplo, papel ou polímero, reduz substancialmente o custo final da etiqueta. Estudos teóricos e práticos, juntamente com simulações eletromagnéticas foram realizados. Dois processos de prototipagem da etiqueta foram executados: um utilizando uma impressora jato de tinta que funciona propelindo gotas de tinta sobre o substrato e o outro utilizando serigrafia ou silkscreen printing que é muito prático para imprimir formas geométricas através de uma tela de fios trançados. Esses métodos de impressão permitiram a produção rápida da antena sem a necessidade de máscaras de fotolitografia, como é amplamente utilizado na indústria eletrônica. Quatro protótipos foram produzidos e medidas foram realizadas para verificar a viabilidade da utilização dessas etiquetas impressas em relação à sua operação, a confiabilidade das informações armazenadas e a troca de dados com o leitor RFID via interface aérea. Os resultados práticos foram comparados com os obtidos de etiquetas comerciais, onde foi possível verificar que a antena fabricada com tinta condutiva é capaz de capturar e radiar ondas eletromagnéticas de forma eficiente, resultando em uma troca de dados confiáveis através da interface aérea. / Radio Frequency Identification Device (RFID), it is a technology using electromagnetic waves for identifying, tracking and management of products, animals and even people without requiring a visual field. Aiming at achieving low costs and using less aggressive manufacturing processes to the environment, it has become important to develop new types of RFID tags. In view of that, manufacturing compact printed antennas using conductive ink represents a good option. The goal of this research is the design of printed antennas on flexible substrates using silver nanoparticles ink. The developing of this type of tags is justified mainly by the following reasons. First, the process reduces the use of chemical agents commonly employed in conventional manufacturing leading to a significant reduction of the environmental impact. Second, the fabrication using substrates such as paper and polymer foils, substantially reduces the final cost of the tags. Theoretical and practical studies along with electromagnetic simulations were conducted. Two process of RFID prototyping were performed: one using an inkjet printer that operates by propelling particles of conductive ink onto the substrate and another using silkscreen printing that is a very practical method to print geometric forms through a twisted wires screen. These technologies allowed fast production of the antenna without requiring photolithographic masks, as it is widely used in the electronics industry. Four prototypes were produced and measurements were taken to verify the feasibility of using RFID tags printed with conductive ink regarding to its operation, reliability of the stored information and the exchange of data with the RFID reader via air interface. Practical results were compared with those obtained of the commercial tags. It was possible to verify that the antenna manufactured with conductive ink was able to capture and radiate efficiently electromagnetic waves, resulting in reliable exchange of data with the reader through the air interface

Stereolitografická tiskárna pro výrobu buněčného kultivačního zařízení / Stereolithographic printer for producing a cell culture deviceGricová, Monika January 2019 (has links)
Stereolithography printing is one of the most popular 3D printing technologies. This printers use a UV light source for photopolymer curing and can be used for a wide range of applications with high precision and excellent print quality. Commercially available printers do not allow the modifications of the optical and mechanical parameters of the instrument. For this reason, a DLP printer has been designed to allow the optical system modifications and thus changing the printing field and resolution. Another advantage is the possibility to modify already designed mechanical parts. The DLP printer has been designed and tested. The recommended printer parameters settings are listed, which are based on the performed experiments.

3D tiskárna FDM se zabudovaným podavačem materiálu / 3D FDM printer with built-in feeder of filamentPuchta, Daniel January 2020 (has links)
This thesis deals with mechanical design of FDM 3D printer with a built-in material feeder with monitoring of remaining material. The aim of this thesis is designing the FDM 3D printer with minimum print volume of 200x200x200 mm and with usage of measured data for optimising the 3D printing process. This 3D printer is targeted to the non-experienced users, so the emphasis was on ease of use and reliability of the printer. Despite the fact that it is an innovative design solution, the suitability of the design was verified experimentally as part of this thesis. The choice of the material feeder design, which is essential for the presented thesis, was justified by the realization of prototypes of two suitable designs, from which the optimal solution was chosen. The knowledge obtained from testing the prototypes was then used for the final design of 3D printer. The usage of data for optimization of the printing process is realized by a C++ compatible source code that is a part of this thesis.
