Abstract
ABSTRACT Bearing in mind the request for increasing diversification of the product spectrum along with the decreasing unit numbers of each production lot, the future innovative production concepts of a flexible and autonomous digitalised production “fifth industrial revolution” tend to substitute more and more the conventional product development and production processes, which so far are reaching their limits or failing to keep up with these trends. In the meanwhile, new technologies like additive manufacturing ultimately create new opportunities regarding vast potentials in product enhancement and manufacturing, but mostly with just insufficient strength regarding structural components, which are being explored and experimenting on intensively in the last decade. Integrating these promising capabilities with powerful optional of Robotic fields to procreate a potent manufacturing trend that is Robotic Additive manufacturing. It is demand full attention the latest and most imperative news that has invaded the media, and scientific and non-scientific journals are about the lack of tools and medical devices needed to cope up with the epidemic of COVID19 that we are living in these days, and about the fierce dispute conflicts between countries over obtaining them and providing their medical staff and citizens with. And then the news continued about the salvation of using of 3D printers to produce certain types of protective face mask from some provided models all over the web or to modify some already existed sportive respirators to use them for medical purposes fill in the shortage and keep up with scarcity.
