the printing apparatus 300 reciprocates along a first direction of the build platform 500 along with the second guide frame 412 and simultaneously can reciprocate along a second direction, the first direction being perpendicular to the second direction;
The movement displacement of the printing device 300 in the second direction is greater than the length of the powder spreading device 200.
specifically, the first direction (Y direction) is parallel to the length direction of the square box on the working area building platform 500, in order to facilitate the continuous work of the printing device 300 and the powder spreading device 200 in cooperation, the printing device 300 does not wait, so the speed ratio of the printing device 300 to the powder spreading device 200 is adjusted, the speed of the printing device 300 is 2-5 times faster than that of the powder spreading device 200, that is, 2 times, 3 times, 4 times or 5 times faster, and the specific selection of the speed of the printing device 300 which is several times faster than that of the powder spreading device 200 is related to the size of the square box and the selection model of the printing device 300 and the powder spreading device 200.
the movement direction of the powder spreading device 200 is a first direction (Y direction) along a horizontal single direction, and the movement direction of the printing device 300 is a first direction and a second direction (X/Y direction) along two horizontal directions which are vertical to each other; when the powder spreading device 200 needs to return after completing unidirectional powder spreading, the printing device 300 moves to the position outside the length range of the powder spreading device 200 along the second direction (the X direction) perpendicular to the powder spreading direction, so that the powder spreading device 200 does not interfere with the printing device 300 or collide with the printing device 300 during return stroke. The specific working process is as follows:
When the printing operation starts, the conveying device 800 drives at least one building platform 500 to enter at least one independent working area, the powder spreading device 200 starts to work first, a layer of powder with a set thickness is uniformly spread above the building platform 500 along a first direction forward direction (Y + direction), when the powder spreading device 200 completes a powder spreading stroke with the width of the printing device 300, the printing device 300 arranged in the same working area with the powder spreading device 200 starts to uniformly spray a first adhesive above the powder spreading device along a second direction forward direction (X + direction) perpendicular to the powder spreading direction, the powder spreading device 200 continuously and normally performs the powder spreading operation in the process of spraying the adhesive by the printing device 300, when the powder spreading device 200 completes a powder spreading stroke with the width of the second printing device 300, the printing device 300 firstly moves a stroke with the width of the printing device 300 along the first direction of the powder spreading direction (Y + direction), then, spraying a second adhesive along the reverse direction (the second direction reverse direction (the X-direction)) opposite to the moving direction of the printing device 300 when spraying the first adhesive, and repeating the steps until the powder paving device 200 and the printing device 300 finish all powder paving and printing operations of the first layer; at this time, the printing device 300 is moved in a direction perpendicular to the moving direction of the powder applying device 200 to a position shifted by the length of the powder applying device 200, so as to ensure that the printing device 300 does not interfere with the powder applying device 200 when the powder applying device 200 performs the powder applying operation in the reverse direction, i.e., the second direction (Y-direction).
similarly, when the powder spreading device 200 completes a powder spreading stroke of the width of the printing device 300 along the first direction reverse direction (Y-direction), the printing device 300 arranged in the same working area with the powder spreading device 200 starts to uniformly spray a first adhesive above the powder layer along the second direction (X direction) perpendicular to the powder spreading direction, and when the powder spreading device 200 completes a powder spreading stroke of the width of the second printing device 300, the printing device 300 firstly moves a stroke of the width of the printing device 300 along the powder spreading direction first direction reverse direction (Y-direction), and then sprays a second adhesive along the reverse direction opposite to the movement direction of the printing device 300 when spraying the first adhesive. And repeating the steps until all subsequent layers are paved and printed layer by layer, and finishing the printing work. The toner spreading device 200 and the printing device 300 are staggered in the horizontal direction.
In the second way, the powder paving device 200 reciprocates along the first direction of the building platform 500 along with the first guide frame 411, and can reciprocate along the third direction at the same time;
The printing apparatus 300 reciprocates along a first direction of the build platform 500 along with the second guide frame 412, and is respectively reciprocatable along a second direction and a third direction, the first direction, the second direction and the third direction being perpendicular to each other;

the specific working process is as follows: when the printing operation starts, the conveying device 800 drives at least one building platform 500 to enter at least one independent working area, the powder spreading device 200 starts to work first, a layer of powder with a settable thickness is uniformly spread above the building platform 500 along the direction of the first direction and the positive direction (Y + direction), when the powder spreading device 200 completes a powder spreading stroke with the width of the printing device 300, the printing device 300 arranged in the same working area with the powder spreading device 200 starts to uniformly spray a first adhesive above the powder spreading device along the direction of the second direction and the positive direction (X + direction) which are perpendicular to the powder spreading direction, the powder spreading device 200 continuously and normally carries out the powder spreading operation in the process of spraying the adhesive by the printing device 300, when the powder spreading device 200 completes the powder spreading stroke with the width of the second printing device 300, the printing device 300 firstly moves a stroke with the width of the printing device 300 along the direction and the first direction of the powder spreading direction and the positive direction (Y + direction), then, reversely (X-direction) jetting a second adhesive along a reverse second direction opposite to the moving direction of the printing device 300 when jetting the first adhesive, and repeating the steps until the powder paving device 200 and the printing device 300 finish all powder paving and printing operations of a first layer; at this time, the printing device 300 moves in the third vertical direction (Z direction) to a position staggered with respect to the height of the powder spreading device 200, so as to ensure that the powder spreading device 200 does not interfere with the printing device 300 when performing the powder spreading operation in the reverse direction (Y-direction) of the first direction.
similarly, when the powder spreading device 200 completes the powder spreading stroke of the width of one printing device 300 along the first direction (Y-direction), the printing device 300 arranged in the same working area with the powder spreading device 200 starts to uniformly spray a first adhesive above the powder layer along the first direction (X-direction) perpendicular to the powder spreading direction, and when the powder spreading device 200 completes the powder spreading stroke of the width of a second printing device 300, the printing device 300 firstly moves a stroke of the width of one printing device 300 along the first direction (Y-direction) of the powder spreading direction, and then sprays a second adhesive along the reverse direction opposite to the moving direction of the printing device 300 when spraying the first adhesive. And repeating the steps until all subsequent layers are paved and printed layer by layer, and finishing the printing work.
