Detailed Description
The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.
In this embodiment, a 3D printing material stitching method includes:
s1, inputting information of the printing material;
s2, acquiring the current printing layer number;
s3, adjusting the pressing force according to the information of the current printing layer number and the printing material;
and S4, printing the material of the current printing layer number, and pressing the current layer by the adjusted pressing force.
Preferably, the information of the printed material includes a diameter and a density of the printed material.
The information of the printing material in this embodiment refers to the diameter and density of the printing material, and it can be understood that the printing material is linear before printing, and forms a 3D printed product after melt extrusion, and the diameter of the printing material refers to the diameter of the linear unprinted printing material.
Due to the difference of the diameter and the density of different printing materials, the deformation degree of the materials is different under a certain pressure.
For ease of understanding, the information on the material can be illustrated by the following formula:
where a is information of the material, d is a diameter of the printed material, and ρ is the diameter of the material.
It can be seen that the material information of the same material is constant.
It can be understood that the 3D printing works by printing layer by layer in a direction away from the printing plate, and after printing one layer in the XY plane, the printing head moves a fixed distance X in a direction perpendicular to the XY plane to start printing the next layer of material.
Preferably, the number of current printed layers is obtained by dividing the total height of the current printed material by the height of a single layer of printed material.
The single-layer printing material height is X.
For ease of understanding, the current number of print layers can be illustrated by the following equation:
wherein n is the current number of printing layers, H is the total height of the current printing material, and X is the height of the single-layer printing material.
Preferably, the total height of the current printed material is obtained by means of a distance measuring device.
For example, the distance may be measured by a laser tester provided on the print head to the print plate.
Preferably, the number of current printing layers is positively correlated with the printing time.
Specifically, the current number of print layers in this embodiment is obtained by the print time.
For ease of understanding, the current number of print layers obtained by the print time can be described by the following equation:
wherein n is the current number of printing layers, v is the moving speed (constant value) of the printing nozzle along the direction vertical to the printing plate, t is the printing time, and X is the height of the single-layer printing material.
It will be appreciated that the pressing force is the pressure applied to the current number of printed layers of material and, for ease of understanding, can be described by the following equation:
p＝p0+Δp
where p is the pressure applied to the material for the current number of layers printed, p0At the initial pressure, Δ p is the compensation pressure.
Further, the initial pressure will be described first, and when the current number of printing layers is one, the pressure applied to the material of the current number of printing layers is the initial pressure p0。
It should be noted that the compensation pressure Δ p is related to the current number of printing layers and information of the printing material, and for the sake of understanding, the following formula can be used for illustration:
wherein, the adjustment of the pressing force, namely the compensation pressure, is positively correlated with the current printing material layer number.
Further, the pressure applied to the material of the current number of printing layers is positively correlated with the printing time.
By gradually increasing the pressure applied to the laminating material with increasing printing time, the layers of the printing material can be tightly attached to each other.
Example (b): the method of changing the magnitude of the pressing force is achieved by changing the distance of the pressing roller relative to the print head.
The height of the single-layer printing material is 0.6mm, namely the distance between the initial distance of the printing nozzle and the printing plate is also 0.6mm, the distance between the press point and the printing plate is 0.3mm, and the distance between the press roller and the printing nozzle is also 0.3 mm. Assuming that the diameter of the material is 0.6mm, the first printed layer height without pressure is 0.6mm, and the first layer height after printing becomes 0.3mm under the pressure of the press roller. After the first layer is printed, the printing nozzle and the compression roller are raised by 0.6mm of layer height, so that the printing nozzle is raised to 1.2mm, the compression roller is raised to 0.9mm, at the moment, the solidified first layer is printed as a printing plate to be printed next layer, the distance between the printing nozzle and the first layer is 0.9mm, the distance between the compression roller and the first layer is 0.6mm, and the diameter of the printing material is still 0.6mm, which means that under the condition that the distance is not changed, the compression roller loses the pressing effect on the material when the second layer is printed, therefore, the distance between the compression roller and the printing nozzle needs to be adjusted, specifically, the pressure applied to the adjusting compression roller is increased, so that the adjusting compression roller moves 0.3mm towards the direction close to the printing plate relative to the printing nozzle, and is attached with the same force, and the compensation function is realized.
Compared with the prior art, the method has the advantages that the current printing layer number is acquired by inputting the information of the printing material, the deformation degree of the printed material can be known, the pressing force is adjusted according to the current printing layer number and the information of the printing material, the specific deformation degree is compensated, the pressing force is compensated, and the two adjacent printing material layers are tightly attached, so that the problems that the material is deformed in the pressing process, the pressure applied to the upper layer material is insufficient and the pressing between the material layers is not tight in the process of tracing the printing are solved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
