The report "Prototypes" is based on the PolyMetal prototypes from the prototype mould. In line with the flexible nature of the mould (inserts with different roughnesses, PolyMetal and Interreg logos), we have produced different surface structures according to the different needs of the partners. These prototype products were also characterised and analysed by the design and marketing departments of the partner companies Gorenje and Intralighting. In addition, prototypes produced by Tehnomat and Tehnoplast Povše are presented. Report "Prototypes"
