Abstract
The invention discloses a 3D printing consumable, which comprises a 3D printing plastic wire, wherein a vacuum-sucking hollow core is arranged in the center of the 3D printing plastic wire. The hollow core is a hollow tube. The 3D printing plastic wire is a shaped 3D printing plastic wire. The invention has the advantages of high printing efficiency, flexible application and wide application.
Description
Technical Field
The invention relates to the field of 3D printing, in particular to a preparation method of 3D printing consumables.
Background
The 3D printing technology is a revolutionary industrial molding technology, raw materials can be directly molded through a 3D printer, the technology is based on a digital model file, an object is constructed by adopting powdery metal or plastic and other bondable materials in a layer-by-layer printing mode, the time and cost for manufacturing a mould are saved, along with the rapid development of the 3D printing technology, the requirements on materials are also rapidly improved, and the existing 3D printing consumables mainly comprise PLA plastic (polylactic acid), ABS, nylon618, PVA and the like. At present, 3D printing wires on the market mainly comprise solid plastics, and in the printing process, errors of relevant parameters such as diameters, sizes, tracks, volumes and the like of the wires are too large, so that printing failure is easily caused. In addition, in the cooling forming process of the 3D printing wire, the external shape belongs to a free state, the fluctuation of the external diameter, the size and the shape is large, and the printing effect is influenced only through the temperature control state of the water tank.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a preparation method of 3D printing consumables with high printing efficiency, flexible application and wide range.
In order to achieve the above purpose, the 3D printing consumable provided by the invention comprises a 3D printing plastic wire, and a vacuum-sucking hollow core is arranged in the center of the 3D printing plastic wire. The hollow core is a hollow tube. The 3D printing plastic wire is a shaped 3D printing plastic wire.
Another object is to provide a method for preparing a 3D printing consumable, specifically as follows:
(1) Extruding the 3D printing plastic wire through an outer mold;
(2) Then, vacuum sucking is carried out on the center of the 3D printing plastic wire by utilizing a vacuum rod, so that a hollow core is formed;
(3) Shaping the 3D printing plastic wire into a 3D printing plastic wire with a hollow core by utilizing a water tank;
(4) During the printing process, the printing effect can be interfered through the hollow position.
In some embodiments, if a medical product is required to be printed, the trace elements are conveyed to the printing head through the hollow core for printing in a manual intervention mode in the printing process.
In some embodiments, if the printed product needs to be cooled during the printing process to avoid deformation of the printed product, the printing process can adopt a manual intervention mode to introduce cold air into the hollow core to avoid deformation of the printed product.
The beneficial effects of the invention are as follows: the 3D printing plastic wire with the hollow core adopts a manual active intervention mode, corresponding materials can be added into the hollow core according to different requirements, the purpose of actively allocating 3D printing consumables is achieved, printing efficiency is guaranteed, and the application process is flexible. In addition, the material passing through the hollow core can be microelements or cold air, so that the application is very wide.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention;
fig. 2 is a schematic diagram of the internal structure of the present invention.
Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1-2, a 3D printing consumable comprises a 3D printing plastic wire 1, and a vacuum-sucking hollow core 2 arranged in the center of the 3D printing plastic wire 1. The hollow core 2 is a hollow pipe. The 3D printing plastic wire 1 is a shaped 3D printing plastic wire 1.
A preparation method of 3D printing consumables comprises the following steps: (1) extruding the 3D printing plastic wire through an outer die; (2) Then, the center of the 3D printing plastic wire 1 is vacuumized by utilizing a vacuum rod, and a hollow core 2 is formed; (3) Shaping the 3D printing plastic wire 1 into a 3D printing plastic wire of a hollow core 2 by using a water tank; (4) During printing, the printing effect can be interfered with by the position of the hollow core 2. If the medical product needs to be printed, the manual intervention mode is adopted in the printing process, and trace elements are conveyed to a printing head for printing through the hollow core 2 before printing. If the printing process is to avoid deformation of the printed product, the printed product needs to be cooled, and the printing process can adopt a manual intervention mode to introduce cold air into the hollow core 2 to avoid deformation of the printed product.
During application, a manual active intervention mode is adopted, corresponding materials can be added to the hollow core 2 according to different requirements, the purpose of 3D printing consumables can be actively allocated, printing efficiency is guaranteed, and the application process is flexible. In addition, the material passing through the hollow core 2 can be microelements or cold air, so that the application is very wide.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
