Description
Technical field
The present invention relates to building 3D printing manufacturing technology fields, and in particular to a kind of 3D printing method of building element.
Background technology
Three-dimensional printing technology is also known as 3D printing technique, is a kind of rapid shaping technique.It is one kind with digital model file
Based on, with adhesive material, carry out the technology of constructed object by layer-by-layer printing.3D printing often mold manufacturing,
The fields such as industrial design are used for modeling, after be also gradually available for the direct manufactures of some products.It also begins to be used in recent years
In the construction of architectural engineering, especially as the wall of main building element, existing 3D printing device for building is pair
Construction wall is successively printed, and there are some following technical problems in actual use:
1, the wall both sides after printing is completed can show the out-of-flatness state formed when successively printing, in order to reach
To preferable aesthetic effect, such building prefabrication wall certainly will increase subsequent decoration cost.
2, the globality of layered structure wall is not good enough, and the factor for influencing wall body structure intensity is mainly:Existing printing
Nozzle cross section is circle, and the wall of layering printing is as the round noodles that multilayer is accumulated in this way, even if in the influence of gravity
For lower aprons in ellipse, contact area is very small, influences the structural strength of wall.
3, there are a contradictions in print procedure, are squeezed out for the ease of concrete from nozzle, concrete are needed to have preferable
Mobility, and in order to ensure the intensity of wall, since concrete being needed to reduce mobility, have certain intensity.
Invention content
It can so that printing metope is smooth the purpose of the present invention is to provide one kind, wall interlayer good connecting effect, and wall
Body can have the 3D printing method of good strength.
In order to solve the above technical problem, the present invention provides a kind of 3D printing method of building element, including controller and
Walking nozzle, the nozzle that the walking nozzle includes the top base of connection material-extruding machine and is rotatably assorted with top base, nozzle lead to
It crosses rotaty step motor and drives rotation, nozzle is by being oppositely arranged and parallel two end plates and two pieces of side plate one being oppositely arranged
It surrounds, two pieces of end plates are each perpendicular to the direction of motion of the nozzle, along the length of the nozzle on two pieces of end plates
Direction is equipped with multiple lug bosses and recessed portion, the lug boss on one piece of end plate and the recessed portion on another piece of end plate
It is correspondingly arranged to realize agreeing with for every layer of wall faying face, rapid hardening is provided on the side plate of the nozzle and smoothes out mechanism, including smearing
Tablet and the overturning stepper motor for being placed in the heating wire of wiping tablet behind and wiping tablet being driven to be flipped up, it is specific to print
Method is as follows:
A, controller control driving part make walking nozzle arrival printing initial position, and adjust nozzle rotation to make end plate
Towards printing direction of travel;
B, controller control driving part make walking nozzle move along a straight line, while material-extruding machine is controlled to be fed for nozzle, row
The product of the speed of travel and exit area of nozzle for walking nozzle is the feeding speed of material-extruding machine;

Stop feed to walking nozzle to the outer angular position of building element, controller control material-extruding machine;
D, controller control driving part, makes nozzle side plate concordant with the corner another side of building element, then controller
Control driving part makes walking nozzle move along a straight line, while material-extruding machine is controlled to be fed for nozzle, and the feeding speed of material-extruding machine subtracts
Half, until walking nozzle, to the inside lock position of building element, the feeding speed of material-extruding machine restores;
E, controller control driving part makes walking nozzle repeat step B, C, D, until walking nozzle returns to initial position
Vertical projection shaft position, at this time controller control driving part make walking nozzle rise, climb be equal to two end plates between
Away from then repeatedly step B, C, D;
F, when building element height is more than wiping tablet height, controller driving overturning stepper motor puts down wiping tablet, and
Heating wire is connected, heating wire temperature is no more than 45 DEG C, and when walking nozzle is to the inside lock position of building element, controller drives simultaneously
It is dynamic to overturn the upward folding wiping tablet of stepper motor and close heating wire, when walking nozzle is driven out to the inside lock position of building element
When, controller drives overturning stepper motor to open wiping tablet downwards and open heating wire simultaneously;
G repeats step B, C, D, E, F until completing the printing of building element;
Then H removes building element, repeat step B, C, D, E, F, G.
It is had the advantages that using the 3D printing method of the building element of above-mentioned technical proposal:1. since nozzle uses
It is oppositely arranged and parallel two end plates is integrally surrounded with two blocks of side plates being oppositely arranged, two pieces of end plates are each perpendicular to described
