China: China Building Materials Academy (CBMA) has patented a new 3D printing method which uses short rebars to reinforce printed layers. The developer says that this will enable builders to ensure structural strength without the disruption caused to 3D printing by the long rebars of conventional building skeletons.

CBMA said that "An inverted U-shaped or inverted L-shaped short rebar is vertically inserted into the cement slurry layer, wherein the bending mechanism comprises two bending members, separately disposed on two sides of a clamp."

Denmark: Switzerland-based Holcim has made an investment in 3D concrete printer supplier COBOD International. Holcim hopes that the investment will help it to further expand its TectorPrint 3D printing ink range. Holcim and COBOD International's collaboration dates to 2019, since which time the partners have 3D printed windmill tower bases in Denmark, a school in Malawi and a housing development in Kenya.

Holcim's head of global research and development, Edelio Bermejo, said “At Holcim, we are continuously expanding our range of building solutions to build better with less, working to improve living standards for all in a sustainable way. 3D concrete printing will help us meet these goals."

Austria: PERI and STRABAG have used a COBOD 3D printer to successfully build Europe’s first 3D printed office building in Hausleiten, Lower Austria.

PERI board member for innovation and marketing Thomas Imbacher said "The building in Hausleiten is a milestone for STRABAG, for PERI, for all involved. We are convinced that 3D printing of buildings will be part of the future of construction, as this technology offers solutions for challenges that are currently occupying our industry: digitalisation, efficiency, shortage of skilled workers and much more."

Australia/Canada: Fortex and Nidus3D have won contracts to become Denmark-based COBOD’s distribution partners for the Australian and Canadian markets respectively. Nidus3D previously printed a multi-unit residential building, the first of its kind in North America, using COBOD’s 3D printing equipment. Meanwhile, the supplier says that its first BOD2 3D printer available on the Australian market will arrive there in late 2022.

Regarding the Australian contract with Fortex, COBOD noted that it will make its equipment available on six different continents.
