Add:north consists of two childhood friends and two brothers, linked via engineering studies at Chalmers University of Technology, who are technical enthusiasts and have a long experience from the plastics industry. When we started to 3D-print, we soon realized that it was a bit tricky to acquire high quality materials and that many resellers had issues with stock levels and deliveries from foreign countries. Therefore, we founded the start-up add:north and moved to a Swedish plastics and entrepreneurship cluster into an old textile factory where the first filament line was set up.
