“I first encountered metallurgy more than 13 years ago, when I first walked through the doors of Ravne steelworks. After finishing my studies, I also got a job there and gained my first experience, which I improved over the years. I started with additive manufacturing technologies at the end of 2018 – this field immediately presented a great challenge to me, especially from the point of view of the development and use of new materials and all the opportunities that these technologies bring. I hope that companies will recognize Additio d.o.o. as a potential partner and supplier in our development activities and that we can only build on this in the future”.
