s81, covering the outer surface of the wall body 100 with a first anti-cracking layer 410;
s82, a plurality of connectors 420 are arranged outside the first crack resistant layer 410 to fix the first crack resistant layer 410; and
s83, spraying an adhesive layer 430 on the outer surface of the first cracking-resistant layer 410.
The first anti-cracking layer 410 is fixed by the connecting piece 420, so that the first anti-cracking layer 410 is prevented from falling off, and the bonding layer 430 can further bond the first anti-cracking layer 410 on the outer side of the heat insulation board, so that the purposes of improving the stability and the anti-cracking effect of the first anti-cracking layer 410 are achieved.
Further, since the cracking effect of one first cracking-resistant layer 410 is limited, it further includes, after step S83:
s84, covering the first anti-cracking layer 410 on the outer surface of the bonding layer 430, and pressing the first anti-cracking layer 410 into the bonding layer 430;
and S85, spraying a second cracking-resistant layer 440 on the outer surface of the first cracking-resistant layer 410.
The pressing of the first crack resistant layer 410 into the bonding layer 430 facilitates bonding of the plurality of crack resistant layers so as to enhance the crack resistant effect of the plurality of first crack resistant layers 410. The second crack resistant layer 440 is advantageous for achieving multiple crack resistant effects of the 3D printed wall.
The second anti-cracking layer 440 is manufactured by spraying through a printing head of the 3D printer, which is beneficial to improving manufacturing efficiency and guaranteeing uniformity of thickness of the second anti-cracking layer 440.
Optionally, step S8 further includes:
s9, the waterproof layer 500 is sprayed on the outer surface of the anti-cracking component 400, the waterproof layer 500 can play a role in protecting the 3D printing wall, the waterproof effect of the 3D printing wall is improved, and the service life of the 3D printing wall is prolonged. It can be appreciated that the waterproof layer 500 is also manufactured by spraying through the printing head of the 3D printer, which is beneficial to improving the manufacturing efficiency and ensuring the uniformity of the thickness of the waterproof layer 500.
Note that the basic principles and main features of the present invention and advantages of the present invention are shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the foregoing embodiments, but rather, the foregoing embodiments and description illustrate the principles of the invention, and that various changes and modifications may be effected therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
