Objetivo The achievements of the project can be summarised as the following: laser processing technologies to produce pseudo 3D patterns on the surface laser processing technologies to obtain colour change effects in the glass special additive for glass and coatings which improve the quality of dry etching by means of laser and are applicable for mass-production special glass which is suitable for laser induced colour change knowledge about change of glass attributes such as mechanical properties due to laser patterning an industrial prototype which can perform dry etching and colour change and is tailored for the specific needs of glass patterning special control environment for the prototype which is suitable for glass patterning and machine programming study on technical and economical evaluation of the laser based pattering of glassThe technology for surface patterning of glass is based in manual mainly techniques such as sand blasting and diamond tools. Although this kind of technology is the only one existing, it does not produce good quality patterns due to the human factor and also the low resolution patterns produced. The use of these techniques in wider area patterning for pseudo-3D-patterns is very expensive and time consuming. On the other hand, patterning in colour of glass, both on the surface and in the bulk material, involves chemical and/or thermochemical procedures that are expensive and produce simple patterns. Over the last years, lasers have found many industrial applications particularly in machining and material processing. Most of these applications concern the treatment of metals and alloys. Lasers offer the advantage and photon energy may be provided in a temporally and spatially controlled manner and in a contact-free and clean process. In this proposal, laser-based patterning techniques will be evaluated and the potential use of the most promising will be fully exploited, both technically and financially. Two different approaches will be investigated. The first one is the "laser-based surface dry etching" of the glass surface that gives the possibility to produce pseudo-3D-patterns. The other one is the "laser triggered colour change" of the glass either on the surface on in the bulk material. During this project, a demonstration pilot machine cell will be developed and tested in order to evaluate the technology developed under working conditions. This prototype will form the basis for future development and production o f machines that use laser for decorative purposes on various materials (glass, marble, wood, metal etc.) Ámbito científico ingeniería y tecnologíaingeniería de materialescoloresingeniería y tecnologíaingeniería mecánicaingeniería de fabricaciónfabricación sustractivaingeniería y tecnologíaingeniería de materialesrecubrimiento y películasciencias socialespsicologíaergonómicaciencias naturalesciencias físicasópticafísica del láser Programa(s) FP3-BRITE/EURAM 2 - Specific programme (EEC) of research and technological development in the field of industrial and materials technologies, 1990-1994 Tema(s) 2.2.1 - Tools, techniques and systems for high quality manufacturing Convocatoria de propuestas Data not available Régimen de financiación CSC - Cost-sharing contracts Coordinador ST GOBAIN RECHERCHE Dirección 39 quai lucien lefranc 93303 Aubervilliers Francia Ver en el mapa Aportación de la UE Sin datos Participantes (4) Ordenar alfabéticamente Ordenar por aportación de la UE Ampliar todo Contraer todo APS GmbH Alemania Aportación de la UE € 0,00 Dirección Reutershagweg 4 52074 Aachen Ver en el mapa Enlaces Sitio web Opens in new window Otras fuentes de financiación Sin datos ERGON SA Grecia Aportación de la UE € 0,00 Dirección P. rallistreet 19 17778 Athens Ver en el mapa Otras fuentes de financiación Sin datos FORTH Grecia Aportación de la UE € 0,00 Dirección P.o. box 1527 71110 Heraklion crete Ver en el mapa Otras fuentes de financiación Sin datos MONOTHERM SA Grecia Aportación de la UE € 0,00 Dirección N. haritou street Karditsa Ver en el mapa Otras fuentes de financiación Sin datos
