The hint of the new generation of cold crucibles was born in 2015 within Officina dei Materiali Sas, a consulting company in the field of materials science and engineering. The idea immediately found a great boost thanks to the first projects that were financed and aimed at modelling the physical phenomena involved during the melting of levitating metals through simulation codes, and at optimizing the technological process of additive manufacturing of pure copper. Taking advantage of its know-how and collaborations with universities and national research laboratories, Officina dei Materiali obtained a scholarship with POR FSE funding from the Veneto Region. After that, the company participated as a lead company in the "Innovative cold crucible" initiative within the project "TEMART", using POR funding - Obiettivo "Incremento dell'attività di innovazione delle imprese" Parte FESR European regional development fund 2014-2020 again from the Veneto Region.
In the first months of 2021, at the end of the project, the first model of a new generation of cold crucibles was produced and tested, which was designed to melt metals and high melting point metal alloys. Inside it, the funnel shape and the number of cuts have been optimized to produce a gradual variation of the levitating force (in order to adapt to alloys of different densities) while maintaining an electromagnetically controllable nozzle of appropriate dimensions for the casting off of the melt. The additive manufacturing implementation exactly followed the complex optimized shape. In addition to many advantages compared to traditional crucibles, the new crucible has shown a considerable capacity to reduce energy consumption, decreasing 3-4 times the consumption of electricity necessary for melting metals in traditional cold crucibles.
Addtoshape Srl was founded in 2022 thanks to the meeting between Seitron Spa, an industrial production company working in Italian and foreign markets for over 40 years, and Officina dei Materials Sas. Addtoshape’s foundation was supported by the strong spirit of innovation and the modern industrial production capacity of Seitron, together with ten years of experience of Officina dei Materials in national research structures, as well as a new patent, registered for protecting the new generation crucible. Seitron, always motivated by the evolution of technology and by the challenges posed by new processes and new markets, has decided to venture into opportunity offered by the metal additive manufacturing of pure copper, in order to support the creation of new generation cold crucibles.
