3D printing construction spray head and embossing method

Abstract

The invention relates to the technical field, and discloses a 3D printing construction spray head and an embossing method, including a housing, the housing is provided with a first cavity and a second cavity, the lower end of the first cavity is connected with a print head, and the second There is an embossing head and a driving mechanism in the cavity, and the product is formed by laying the printing head layer by layer. The controller controls the driving mechanism to drive the embossing head on the laying of the printing head according to the embossing pressure value of the printed pattern. Patterns are embossed on building materials. Since the print head and embossing head are set separately, the embossing head is not limited by the size of the print head and the printing speed. It can be controlled separately through the driving mechanism according to the specific requirements of the pattern. Better, and since the print head and the embossing head are arranged on the same housing, the embossing head can emboss the pattern pattern on the building material laid by the printing head in time before the building material is solidified and hardened after the printing head completes printing. Imprint construction efficiency is improved.

Description

Technical field [0001] The present invention relates to the technical field of 3D printing, and more particularly to a 3D printing building nozzle and an imprint method. Background technique [0002] With the development of 3D printing technology, 3D printing is more and more applied in the construction industry. 3D printing buildings are emerging technologies that use industrial robots to replicate the free form of material layer components by layer, and finally form a finished product by layered, in order to enhance the aesthetics of printing products, in the printing process, print nozzle Under the action of pressure, the thickness of the material changes, and press a certain motion trajectory in accordance with a pre-set computer program to press the undulating pattern or the pattern in the surface of the material. [0003] For general 3D printing techniques, printing structures are generally small, using small printheads to meet both print speed requirements, can also meet t...

AI Technical Summary

Problems solved by technology

[0003] For general 3D printing technology, the printed structures are generally relatively small. Using a small print head can not only meet the printing speed requirements, but also meet the precision requirements of the structure, and can also print some vivid patterns. For the construction industry 3D printers, the buildings to be printed are much larger than ordinary small structures, and the nozzles of the corresponding printers are also much larger. In the actual printing process, for some detailed patterns, such as patterns and other effects, large-scale The nozzle cannot meet the printing requirements due to its own size and operating speed limitations, and additional embossing operations are required in the later stage. Since the building materials gradually condense and harden during the layer-by-layer accumulation process, it brings great difficulties to the later imprinting operations. , which greatly reduces the construction efficiency
