Title:
AUTO-AGITATING NOZZLE FOR CONSTRUCTION 3D PRINTER
Document Type and Number:
WIPO Patent Application WO/2022/270813
Kind Code:
A1
Abstract:
The present invention relates to a 3D printer for construction that prints out various structures, in which a stirring blade (45) capable of auto rotation is mounted inside a nozzle (10) for discharging a printout such as concrete or mortar, thereby enabling the agitation of a fluidized bed printout. The present invention makes it possible to smoothly agitate the fluidized bed printout inside a nozzle (10) of the 3D printer for construction, thereby preventing separation of materials and maintaining a homogeneous mixing state of each material constituting the fluidized bed printout.
