Problems solved by technology

However, in this method, the printing head is easy to pull the raw material during the movement, which affects printing. At the same time, because the temperature of the printing head and the printing material just extruded from the printing head is high, the entire 3D printer has to choose a more cost-effective solution for high temperature resistance. High temperature resistant parts, and the materials of some parts cannot withstand high temperature, so it is impossible to print in high temperature environment

Embodiment 1

[0038] Please refer to Figure 1-4 , Embodiment 1 of the present invention is:

[0039] A 3D printer, comprising a printing head 1, a raw material tray 2, a cover plate 3, a heat shield 4, a printing platform 5, a lift table 6, an X-axis motor 71, an X-axis slide rail 72, a Y-axis motor 81, and a Y-axis slide Rail 82, Z-axis motor 91 and Z-axis slide bar 92;

[0040] The print head 1 and the raw material tray 2 are respectively arranged on the upper surface of the cover plate 3, the cover plate 3 is arranged parallel to the printing platform 5, and the printing platform 5 is arranged below the cover plate 3, and the print head 1 The discharge nozzle 11 passes through the cover plate 3 and faces the printing platform 5;

[0041] The heat shield 4 is a hollow structure with openings at both ends, the material of the heat shield 4 is silica gel, and the heat shield 4 is an inverted terrace structure;

[0042] One end of the heat shield 4 is connected to the lower surface of th...

Abstract

The invention discloses a 3D printer. The 3D printer comprises a printing head, a printing platform, a cover plate and a heat shield, the printing platform and the cover plate are oppositely arranged,and the heat shield is made of an elastic material; and the printing platform, the cover plate and the heat shield enclose to form closed printing space, the printing platform is movably disposed relative to the cover plate, and a discharging nozzle of the printing head is disposed in the printing space. The printing head is not moved when the 3D printer is working, and the printing platform is moved, so that an existing printing mode is changed; since the distance between the printing head and a raw material tray is fixed, no raw material is pulled; during the operation of the printer, the temperature generated by the printing head is limited to the space enclosed by the cover plate, the printing platform and the heat shield, and other parts of the printer do not need special high temperature resistant materials; and at the same time, better energy-saving property and better constant temperature performance are achieved because of a small high-temperature area, thereby reducing the cost and achieving high-temperature printing.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] When the existing 3D printer is working, the printing head is under the control of the computer and moves according to the cross-sectional profile information of the product parts. The material is heated and melted in the nozzle to become a semi-liquid state, and then extruded out for selective coating. On the printing platform, the thin profile is formed after rapid cooling. After the cross-section of one layer is formed, the printing platform is lowered to a certain height, and then the cladding of the next layer is carried out, and this cycle is repeated to finally form a three-dimensional product part. However, in this method, the printing head is easy to pull the raw material during the movement, which affects printing. At the same time, because the temperature of the printing head and the printing material just extruded from ...
