This diploma thesis deals with the surface modification of 3D printed metallic materials. The research part presents the most used methods of additive manufacturing and their process parameters influencing the quality of printed components. Defects arising during these processes and the techniques used to eliminate them are also described. In the experimental part of the work, the optimization of electrochemical polishing parameters was performed. The aim was to modify the rough surface of the components and thus prevent the formation of defects on the surface. The mechanical properties were investigated by means of three-point bending under static and dynamic loading. Fractographic analysis was performed on the quarry surfaces.

Organic electronic biosensors are developed as suitable devices that can transform electrochemical processes within the cell membrane into an electronic signal and enable to measure electrical activity of excitable cells and tissues both in vitro and in vivo and thus represent valuable alternative to current cell monitoring methods. In this work we focus on the fabrication of electrophysiological sensors based on organic semiconductors printed by the material printing method. Microelectrode arrays (MEAs) are active components of the device, which can monitore cellular activity and above that stimulating cells with electrical pulses. The proposed platform should be used for cytotoxicity of potential drugs especially on cardiac cells (cardiomyocytes). The experimental part focus on specific production processes of platforms, which were prepared in the laboraty with emphasis on biocompatibility and conductivity of device.

L'émergence d'un nouveau médium ne laisse jamais intacts les médias qui l'ont précédé (McLuhan, Debray). Cette logique n'échappe pas au paradigme actuel, théâtre d'un bousculement majeur depuis l'apparition des technologies numériques. C'est ainsi qu'à l'heure du post-lnternet, le médium imprimé demeure telle une épave échouée sur la rive du progrès. Du fait de cet état, les mécanismes de ce médium s'offrent dans leur plus simple appareil à l'imagination des artistes contemporains qui, par l'usage de stratégies diverses, en développent de singuliers emplois - réveillant ce médium à l'instar d'un zombie (Parikka & Hertz). Cette thèse entreprend de présenter quelques-unes de ces nouvelles affordances (Norman) du médium imprimé développées depuis les années 2000 par une sélection d'artistes internationaux et par l'auteur, en solo et en collectif, à partir desquelles il s'agira de répondre à la question suivante : pourquoi imprimons-nous (nous, les artistes) encore ? Pour ce faire, l'auteur a forgé trois concepts : « ur-imprimo », « nouvel impressionnisme » et « exo-digital ». Au contact de ces derniers, l'auteur entend déplacer le centre de gravité des analyses médiatiques du médium imprimé en art des questions de reproductibilité (Benjamin), de mécanisation, d'uniformité et de fixité (McLuhan), vers les notions d'empreinte (Didi-Huberman), de trace (Derrida), de pratique vivante et de bricolage (Lévi-Strauss). Subséquemment à cette reprogrammation, l'estampe fait place au « printwork » (Cramer) et la figure du graveur à celle de l'artiste-imprimeur. / The emergence of a new medium never leaves intact the media which preceded it (McLuhan, Debray). Being the scene of a radical shift since the advent of new technologies, the actual paradigm is obviously not immune to this logic. That is why, in these limes of post-digital printed matter remains like a wreck on the shores of progress. As a result, the medium's mechanisms are offered to contemporary artists' imagination who, through the use of various strategies, develop singular new functions within it - awakening this medium like a zombie (Parikka & Hertz). This essay undertakes to present some of the new affordances (Norman) of the printed medium developed since the 2000's by a selection of international artists and by the author, alone or as a collective, from which the intent will be to answer the following question: why do we (artists) still print? ln order to do so, the author has forged three concepts: "ur-imprimo", "nouvel impressionnisme" and "exo-digital". With these concepts, the author thus intends to shift the center of gravity of the mediatic analysis of the printed medium in art from the question of replication (Benjamin), mechanization, uniformity and steadiness (McLuhan) towards the notions of imprint (Didi-Huberman), trace (Derrida), living artistic practice and do-it-yourself (Lévi-Strauss). Subsequently to this reprogramming, etching makes room for "printwork" (Cramer) and the printmaker becomes the artist-printer.

In today’s society many non-renewable and environmentally harming energy sources are used to facilitate people’s everyday energy demands. This causes ecosystems to break down, global temperatures to rise, pollution and many more critical long lasting problems. By replacing non-renewable energy sources and taking advantage of the 100% renewable energy source, light, these problems will diminish. This project has been in collaboration with a company called Epishine who develop indoor organic solar cell devices to be able to replace conventual battery driven electrical devices with solar power harvested from indoor light. Since there is no good existing contacting solution, for Epishine to be able to enter the market, a contact solution between their solar cell device and the electrical devices it will power has to be developed. This thesis focuses on developing, designing, testing and evaluating the performance of new contact solutions for encapsulated flexible organic printed solar cells with the feasibility, viability, scalability and durability in focus. This project was conducted by first performing a literature study, thereafter, establishing a baseline for future referencing of new contact solutions and the main part, developing new concepts and evaluating them. By using the design thinking method, an iterative process could take place, allowing for a constant flow of new ideas whilst testing concepts throughout the project. The baseline tests were successful and the hypothesis of organic materials degrading over time was confirmed. From the many sub-concepts and production methods for a new contacting solution, two concepts showed promising results and were merged into one main concept. Two devices were created with the new concept, one functional device and one showing the design. To conclude, the thesis resulted in a functional solar cell device with a new contact solution which shows great potential and a new production method which enables all organic printed electronics to be design and developed in a more compact and component dense design. This production method is beneficial to not only Epishine, but everywhere where printed electronics are used and need to be optimized due to restrictions such as space and weight. / I dagens samhälle används många icke-förnybara energikällor för att underlätta människans vardagliga behov men skadar samtidigt miljön. Detta leder till att hela ekosystem fallerar, den globala temperaturen stiger, giftiga ämnen släpps fria och flera kritiska, långvariga problem skapas. Genom att byta ut icke-förnybara energikällor och istället dra nytta av den 100 % förnybara energikällan, ljus, kommer dessa ovanstående problem att minska. Detta projekt har varit i samarbete med ett företag vid namn Epishine som utvecklar organiska solcellsenheter för inomhusbruk, för att kunna ersätta konventionella batteridrivna elektriska apparater med solenergi tillvaratagen av inomhusbelysning. I dagsläget finns det ingen bra kontaktlösning mellan solcellsenheten och den apparat den ska driva, vilket är ett av Epishines större problem i nuläget, som hindrar dem från att kunna slå igenom på marknaden. Denna avhandling fokuserar på att utveckla, designa, testa och utvärdera prestandan av nya kontaktlösningar för inkapslade flexibla organiska solceller. Projektet började med en litteraturstudie, därefter etablerades en ”baseline” för att kunna jämföra de nya kontaktlösningarna. Största delen av rapporten handlar om att utveckla och testa nya kontaktlösningar för att sedan utvärdera dem. Genom att använda ”Design thinking” processen, kunde en iterativ process äga rum, vilket möjliggjorde ett konstant flöde med nya idéer som genererades samtidigt som koncept och prototyper utvecklades och utvärderades. Resultaten av ”baseline”-testerna var framgångsrika och hypotesen om att de konduktiva egenskaperna av organiska material försämras med tiden bekräftades. Från alla delkoncept och potentiella produktionsmetoderna för en ny kontaktlösning visade två koncept lovande resultat och slogs därför samman till ett huvudkoncept. Två olika solcellsenheter skapades med den nya kontaktlösningen implementerad. En funktionell enhet skapades och en enhet som visar layouten och designen. Sammanfattningsvis resulterade avhandlingen i en funktionell solcellsenhet med en ny kontaktlösning som visar stor potential samt en ny produktionsmetod som gör att all organisk tryckt elektronik kan designas och tillverkas i en mer kompakt och komponenttät design. Denna produktionsmetod är en fördel inte bara för Epishine utan också överallt där tryckt elektronik används och behöver optimeras i form av utrymme och vikt.

The diploma thesis Printed Independent Magazines in Post-Digital Age tries to discover the motivation of editors-in-chief/art directors for creating a printed, independent magazine in Central Europe and at the same time how these magazines are influenced by post-digital trends. It uses a qualitative method of Grounded Theory based on data from semi-structured interviews. In the practical part of the research, nine authors from Austria, Germany, Poland, the Czech Republic, Slovakia, and Hungary were approached. From the total number of respondents, data was obtained from seven of them. In the theoretical part, the work is focused on the history of independent print, in terms of technological changes in the printing field and it defines the term "printed independent magazine". The main contribution of the work is a mapping of the Central European independent magazine scene, which has not been thoroughly examined in any academic work yet. The text puts this scene in the international context, and it points out the certain specifics which are associated with Central Europe.
