1. Apis Cor
Apis Cor is a Russian company that has developed a 3D printer capable of building a house in just 24 hours. The machine is 4.5 metres long, 1.5 metres high and wide, and can be easily transported by crane. It is a polar 3D printer that extrudes concrete on a 132m² printing surface, rather than a printer installed on a gantry and rails. Moreover, the printer can be set up on-site within 30 minutes! Apis Cor have since developed their own software for the printer, along with a control program to facilitate construction work.
