Abstract

The invention discloses a continuous feeding system for a building 3D printer. The system comprises a continuous pulper, a spiral pumper and a stirring spiral extruder, wherein the continuous pulper comprises a stirring stock bin and a spiral discharge pipeline communicating to the stirring stock bin; the discharge port of the spiral discharge pipeline is connected to the feed inlet of the spiralpumper, and the feed inlet of the spiral pumper is connected to the feed inlet of the stirring spiral extruder; and the stirring spiral extruder comprises a stirring stock bin and a stirring blade shaft and a cone-shaped screw arranged in the stirring stock bin. Continuous intermittent feeding of the printer is achieved by efficient pulping by the continuous pulper and multi-level buffering of thestirring stock bin of the continuous pulper, the spiral pumper and a stirring hopper of the stirring spiral extruder.

Description

technical field [0001] The invention relates to the field of architectural 3D printing, in particular to a continuous feeding system for architectural 3D printers. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on three-dimensional digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Architectural 3D printing technology is a new application developed on the basis of FDM (Fused Deposition Modeling). Its principle is to use 3D slicing software to slice and layer the 3D model of building components to generate printer motion codes, and then the three-coordinate mobile platform of the printer Drive the extruder to extrude special cement mortar layer by layer, and stack it multiple times to form building components with practical functions. [0003] At present, due to the large size of printed building components and the influence of...
