Technical Field

The invention relates to the technical field of 3D printing, in particular to a method for controlling the width and thickness of ink of a 3D printing nozzle.

Background

The 3D printing building technology is to utilize the ink to be stacked layer by layer and to be extruded to enable the upper and lower layers to be tightly bonded, and to control the thickness and width of the printed ink by utilizing the change of the height distance between each layer of the path of the nozzle, and how to control the 3D printing material to be stable is the problem that the inventor needs to solve.

Disclosure of Invention

Aiming at the defects in the prior art, the invention mainly aims to provide a control method for reasonably controlling the height and the width of an ink layer to achieve the best stable effect.

In order to achieve the purpose, the invention provides the following technical scheme: a method for controlling the width and thickness of printing ink of a 3D printing nozzle comprises the 3D printing nozzle and a plurality of printing ink layers which are sprayed by the 3D printing nozzle and are arranged in a stacked mode, and comprises the following steps:

s1, setting the height H and the width L between the ink layers according to the printed object and determining the diameter D of the 3D printing nozzle;

s2, setting the height of the 3D printing nozzle to enable the range of H to be 1/10 × D to be not more than H and not more than 2/3 × D;

and S3, changing the width L with the change of H, wherein the range of L is the volume of the ink layer divided by the height and the length of the ink layer.

Preferably, the height H in step S1 is the same as the height that the 3D print head is raised after printing one layer.

Preferably, the aggregate used in the ink layer has a maximum particle size of 10 meshes.

Preferably, the H is not less than 3 mm.

Compared with the prior art, the invention has the advantages that the thickness and the width of the printed ink are controlled by utilizing the change of the height distance between each layer of the paths of the spray head, the 3D printing and building technology is that the upper layer and the lower layer can be tightly adhered by utilizing the overlapping and the extrusion of the ink layer by layer, certainly, the 3D printing and building technology has a height range, namely the diameter D of the printing spray head, the height distance between the paths has a range value which cannot be lower than 3mm, 3mm is a minimum limit value, and the maximum particle size of aggregate used in the ink is about 10 meshes, namely the diameter is 2 mm. The maximum range cannot exceed the inner diameter of the printing nozzle, and the maximum limit is not reasonable, because if the height of stacking layers is just the inner diameter of the printing nozzle, the upper layer and the lower layer are just contacted, so that the contact surface is few, and the printing nozzle cannot be poured out. The most preferred height range is 1/10 × D ≦ 2/3 × D. The width L changes with the change of H, and the range of L is the volume of the ink layer divided by the height and the length of the ink layer.

Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1, a method for controlling the width and thickness of ink for a 3D printing head includes a 3D printing head 1 and a plurality of ink layers 2 stacked and sprayed by the 3D printing head 1, and includes the following steps:

s2, setting the height of the 3D printing nozzle 1 to enable the range of H to be 1/10 × D to be not more than H and not more than 2/3 × D;

s3, the width L varies with H, and the range of L is the volume of the ink layer 2 divided by the height and length of the ink layer 2.

Preferably, the height H in the step S1 is the same as the height that the 3D print head 1 is lifted after printing one layer.

Preferably, the aggregate used in the ink layer 2 has a maximum particle size of 10 meshes.

Preferably, the H is not less than 3 mm.

The thickness and the width of printing ink are controlled to the change of the height distance between each layer of the path of the spray head, the 3D printing building technology is that the upper layer and the lower layer can be tightly bonded by utilizing the stacking and the extrusion of the ink layer 2, of course, the height distance has a height range, namely the diameter D of the printing spray head, the height distance between the paths has a range value which cannot be less than 3mm, 3mm is a minimum limit value, and the maximum particle size of aggregate used in the printing ink is about 10 meshes, namely the diameter is 2 mm. The maximum range cannot exceed the inner diameter of the printing nozzle, and the maximum limit is not reasonable, because if the height of stacking layers is just the inner diameter of the printing nozzle, the upper layer and the lower layer are just contacted, so that the contact surface is few, and the printing nozzle cannot be poured out. The most preferred height range is 1/10 × D ≦ 2/3 × D. The width L varies with the variation of H, and the range of L is the volume of the ink layer 2 divided by the height and length of the ink layer 2.
