Abstract
The utility model provides a special-shaped nozzle and space 3D printer for space 3D prints. The special-shaped nozzle for spatial 3D printing comprises a nozzle feeding end and a nozzle, wherein a discharge hole of the nozzle is special-shaped, and the area ratio of the circumference of the discharge hole is greater than 1/circumference. When the 3d printing material is extruded to the nozzle from the screw barrel, the printing material is shaped in the nozzle special-shaped flow channel according to the shape of the nozzle discharge port, and under the characteristic of extrusion and expansion of the material, the material flows out of the nozzle discharge port in a shape slightly larger than the outline of the nozzle discharge port. The extruded material has a large area-volume ratio, so that the cooling speed is extremely high, the outer diameter is larger under the same extrusion sectional area, the torsion resistance and the bending resistance are obviously improved, the same finished product strength can be obtained by using less extrusion materials, and the space printing speed is improved.
Description
Technical Field
The utility model relates to a be used for space 3D to print and use nozzle technical field.
Background
Spatial printing is an emerging 3d printing approach, and compared with the conventional FDM3d printing technique, spatial printing can be "grown" directly in space without stacking layer by layer. The printing mode has the advantages that the forming speed is high, the materials are saved, the frame is used for replacing the body, and the printing mode is very suitable for certain printing scenes which need large non-solid filling amount and need to consider the weight.
In large space printing, cooling has been a problem. The conventional circular nozzle limits the printing speed of the space 3d printing in the face of extrusion diameters of more than 6 mm.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above-mentioned not enough of prior art, provide a space 3D of improved generation prints and uses special-shaped nozzle.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the special-shaped nozzle for spatial 3D printing comprises a nozzle feeding end and a nozzle, wherein the shape of a discharging hole of the nozzle is special, and the area ratio of the circumference of the discharging hole is more than 1/circumference.
Furthermore, the shape of the discharge port of the nozzle is Y-shaped, cross-shaped, star-shaped and the like.
Furthermore, the total length of the special-shaped nozzle is 40mm-200mm, and the length of the special-shaped flow channel is 5-195 mm. The special-shaped flow channel does not comprise a nozzle feeding end.
Furthermore, the feed end of the nozzle is directly or indirectly fixed on the screw discharge port of the extruder in a flange fixing or thread fastening mode.
The utility model has the advantages that:
and when the 3d printing material is extruded to the nozzle from the screw barrel, the printing material is shaped in the nozzle special-shaped flow channel according to the shape of the nozzle discharge port, and under the characteristic of extrusion and expansion of the material, the material flows out of the nozzle discharge port in a shape slightly larger than the profile of the nozzle discharge port. The extruded material has a large area-to-volume ratio, so that the cooling speed is extremely high, the outer diameter is larger under the same extrusion sectional area, and the torsion resistance and the bending resistance are obviously improved.
It can be seen that, the utility model provides a special-shaped nozzle for space 3D prints, 1) can obtain the same finished product intensity with less material of extruding, 2) can carry out the space with faster speed and print.
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

Detailed Description
As shown in figure 1, the utility model provides a special-shaped nozzle for space 3D prints, including nozzle feed end 1 and nozzle 2, its discharge gate 3 shapes of nozzle 2 be special-shaped, the perimeter area ratio of discharge gate 3 is greater than 1/girth.
The shape of the nozzle discharge port 3 can be further selected to be Y-shaped, cross-shaped or x-shaped.
In a preferred embodiment, the overall length of the profiled nozzle is in the range of 40mm to 200 mm. The special-shaped flow channel in the special-shaped nozzle does not comprise a nozzle feeding end, and the length of the special-shaped flow channel is preferably 5-195 mm.
When the device is used, the feeding end of the nozzle is directly or indirectly fixed on a screw discharge port of the extruder in a flange fixing or thread fastening mode.
And when the 3d printing material is extruded to the special-shaped nozzle from the screw barrel, the printing material is shaped in the special-shaped flow channel according to the shape of the nozzle discharge port, and under the characteristic of extrusion and expansion of the material, the material flows out of the nozzle discharge port in a shape slightly larger than the profile of the nozzle discharge port. The extruded material has a larger area-volume ratio due to the special-shaped discharge port, so that the cooling speed is extremely high, the outer diameter is larger under the same extrusion sectional area, the torsion resistance and the bending resistance are obviously improved, and the printing speed of space 3d printing is improved.
The above description is given for the purpose of illustrating the preferred embodiments of the present invention, but the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope of the present invention defined by the claims.
