Title (EN) LASER MACHINED REPLICATION TOOLING
(FR) DISPOSITIF DE REPLICATION USINES PAR LASER
Abstract:
(EN) The invention relates to a method of manufacturing a replication master tooling article suitable for manufacturing replicated articles by machining a substrate surface with laser energy to produce a plurality of geometric structures in the substrate, the geometric structures having side surfaces extending from the surface of the substrate into the substrate.
(FR) L'invention concerne un procédé de fabrication d'un dispositif maître de réplication convenant à la fabrication d'articles répliqués. Le procédé consiste à usiner une surface de substrat avec une énergie laser pour produire une pluralité de structures géométriques dans le substrat. Ces structures géométriques ont des surfaces latérales s'étendant depuis la surface du substrat vers l'intérieur du substrat.
