3D printer with power-off protection

Abstract

The invention discloses a 3D printer with power-off protection, comprising: a casing, a printing controller, a backup power supply, an external power supply and a power adapter, the printing controller and the backup power supply are arranged inside the casing, and the printing controller communicates with the external power supply through the power adapter Electrical connection, the external power supply, power adapter and printing controller are connected in series to form a circuit, and the backup power supply is connected to the printing controller in parallel. device. The 3D printer with power-off protection overcomes the 3D printer in the prior art when it encounters a power-off situation during the printing process, and cannot continue printing after printing before the power-off, resulting in waste of 3D printing materials and prolonged printing time; if The external circuit is unstable and frequent startup will also reduce the life of the 3D printer.

Description

Technical field [0001] The invention relates to the field of 3D printers, in particular to a 3D printer with power-off protection. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of cumulative manufacturing technology, that is, a kind of machine of rapid prototyping technology. It is based on a digital model file and can be bonded with special wax materials, powdered metals or plastics. Materials, by printing layers of adhesive materials to create three-dimensional objects. At this stage 3D printers are used to manufacture products. The technique of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the procedure. [0003] During the printing process, the 3D printer in the prior art will stop printing when it encounters a power failure. The printer will restart when it is connected ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned technical problems, the purpose of the present invention is to overcome the 3D printer in the prior art. When encountering a power failure during the printing process, the printing will be stopped, and the printer will restart when the power is connected again. The 3D printer needs to re-import the 3D printing digital data. The file model cannot be connected to the printing before the power failure to continue printing, resulting in waste of 3D printing materials and prolonged printing time; if the external circuit is unstable and frequently started, it will also reduce the life of the 3D printer. During use, the power failure can be effectively handled to prevent the waste of printing time for 3D printing materials, and also avoid the 3D printer with power failure protection that reduces the life of the 3D printer due to frequent startup.
