Foldable Structure for 3D Printer for Building Construction and Methods for Operating the Same
10 Nov 22
A foldable structure for supporting a 3D printer for building components, the foldable structure having expanded and compact positions includes: first supports spaced apart from each other in a first direction and extending in a second direction intersecting the first direction to support the foldable structure on a ground surface; second supports disposed respectively on the first supports, and being supported in a third direction for linear movement along the first supports in the second direction in the expanded position of the foldable structure; and a third support disposed between the second supports.

Nozzle Assembly for 3D Printer of Building Construction and Methods for Operating the Same
27 Oct 22
a nozzle assembly for a 3D printer of building construction includes: a chamber to contain a flowable mixture to form a constructional material layer; an outlet to discharge the flowable mixture in a first direction, the outlet being supported for movement in a second direction intersecting the first direction; and an edge smoothing device extending in the first direction from the lower end of the outlet to guide the flow of the flowable mixture discharged from the outlet and to provide a substantially flat side surfaces of the constructional material layer formed according to the movement of the outlet in the second direction.
