Description
Technical Field
The utility model belongs to the technical field of the vibration material disk and specifically relates to an aluminum alloy wire material 3D printing device.
Background
It is well known that: 3D printing is one of the rapid prototyping technologies, which is a technology for constructing an object by using an adhesive material such as powdered metal or plastic and the like in a layer-by-layer printing manner on the basis of a digital model file. The 3D printing has various process implementations, such as extrusion stack molding, laser photocuring molding, sheet lamination molding, and the like.
In the 3D printing field, for example, the printed material plays a very important role all the time, so the 3D printed material is an important material basis for the development of the 3D printing technology, and to some extent, the development of the material determines whether the 3D printing can be more widely applied.
At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials, pottery holding buckets and the like, and besides, food materials such as color gypsum materials, human bone meal, cell biological raw materials, granulated sugar and the like are also applied to the field of 3D printing.
The raw materials used for 3D printing are developed specifically for 3D printing equipment and processes, and are distinguished from common slag plastics, gypsum, resin and the like, and the forms thereof generally include powder, thread, laminated sheet, liquid and the like. Generally, the particle size of the used bundled 3D printing material varies from 1 to 100 μm depending on the type of printing apparatus and operating conditions, and the powder is generally required to have a high sphericity in order to maintain good fluidity of the powder.
The aluminum alloy material is also one of 3D printing materials, and the aluminum alloy is an alloy formed by adding one or more other elements (such as copper, magnesium, silicon, manganese, zinc and the like) on the basis of aluminum, so that the strength is improved. The aluminum alloy has good corrosion resistance and processability.
The use of aluminium in 3D printing has the following advantages:
1. the melting point is low. Aluminum has a low melting point, so its 3D printing laser sintering temperature is much lower than other metal materials.
2. The density is small. Aluminum can be used to make light structures, known as "" fugitive metals "". The support requirements for printing the article are lower than for other metallic materials.
3. It can be strengthened. Pure aluminum is not so strong that it can be made into an aluminum alloy by adding various elements to improve its strength.
4. Good plasticity and easy processing. The aluminum can be used for drawing pipes and filaments and extruding into various shapes. There are also studies reported using aluminum materials for FDM printing.
The existing 3D printer based on extrusion molding mostly adopts melt extrusion molding (FDM), and the basic principle of such technology is: under the action of driving force provided by two (or more) friction wheels driven by a motor, wires are sent to a plasticizing and melting device, the wires sent in firstly are gradually softened and melted, the unmelted wires carry out piston extrusion on the melted wires, the melted wires are extruded out from a nozzle at a certain speed, and a spray head moves along a scanning planning path to form a material stacking path, so that melting and extrusion forming are realized.
The nozzle device has simple structure and stable feeding, and quantitatively extrudes and melts the wires, in the prior art, the plasticizing and melting device is generally arranged at the front end of the nozzle, and the wires entering the plasticizing and melting device are supplied through the wire disc; however, a wire supply device is arranged between the wire disc and the plasticizing and melting device, and the plasticizing and melting device and the wire supply device are generally connected through a heat-resistant pipe; the wire material is conveyed into a plasticizing and melting device through a heat-resistant pipe. In the printing process, as the spray head moves along the scanning planning path, one end of the heat-resistant pipe connected with the plasticizing and melting device moves along with the spray head, so that the wire supply path is changed, the supply speed of the wire supply device cannot be controlled, and the condition that the material supply is delayed or the nozzle overflows can be caused. Therefore, the stability of the printing operation is poor, and the supply of the wire cannot be guaranteed. Meanwhile, in the device, the arrangement of the silk material supply device is not arranged on the printing device, so that the supply route of the silk material supply device is long, and the installation and the arrangement are not easy.
