Holcim’s 14Trees beats other 3D printing companies in the race to create affordable housing. From October 2022 to January 2023, 14Trees 3D printed 10 houses in Kilifi in Kenya, averaging one house per week. With 6 three-bedrooms (836 SF) and 4 two-bedrooms (616 SF) houses have been 3D printed so far, making Mvule Gardens in Kilifi the largest 3D printed project to date using BOD2 printer from COBOD. The fastest time to print one house in the Mvule Gardens project was 18 hours.For a long time, 3D construction printing has been seen as a possible solution to the escalating affordable housing crisis. Proponents of the technology claim, that when 3D printing projects in construction are carried out at scale, the advantages of the technology become clear. Evidence of that claim has been lacking, but recent developments actually provide credibility to the statement.14Trees is a joint venture company between the cement and concrete giant Holcim and British International Investment dedicated to accelerating the provision of affordable housing in Africa. The joint venture is behind the first 3D printed houses in Africa and the first 3D printed schools in the world. This week 14Trees announced some of the initial results of their efforts to 3D print up to 52 houses in Kilifi, Kenya, using a single BOD2 printer from COBOD. The BOD2 is the world’s best-selling construction 3D printer. Following the start in October 2022, 14Trees completed the 3D printing of the walls of 10 houses in January 2023 after just 10 weeks using only one printer.
