China Building Materials Academy patents 3D printing method
04 October 2022China: China Building Materials Academy 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.
China Building Materials Academy 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.'
