It will be understood by those skilled in the art that the modules or steps of the invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of computing devices, and optionally they may be implemented by program code executable by a computing device, such that it may be stored in a memory device and executed by a computing device, or it may be separately fabricated into various integrated circuit modules, or it may be fabricated by fabricating a plurality of modules or steps thereof into a single integrated circuit module. Thus, the present invention is not limited to any specific combination of hardware and software.

It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments illustrated herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.

Claims

1. A parts printing method applied to a printing system including a printing apparatus and an erasing apparatus, the method comprising:

2. The parts printing method according to claim 1, wherein determining an area to be planned on an upper surface of the supporting unit includes:

3. The part printing method of claim 1, wherein controlling the printing device to fill the area to be planned with a second material layer by layer comprises:

4. The parts printing method according to claim 1, wherein when the first material is a high-temperature soluble material and the second material is a high-temperature insoluble material, the removing device is a heating device, and accordingly, the controlling of the removing device to remove the supporting unit included in the composite body based on a predetermined manner includes:

5. The parts printing method according to claim 1, wherein the first material is a soluble material soluble in a predetermined dissolving agent, and when the second material is insoluble in the soluble material of the predetermined dissolving agent, the removing device is a dissolving device, and accordingly, the supporting unit included in the composite body is removed by a predetermined manner, the method comprising:

6. The part printing method according to claim 1, further comprising, after controlling the eliminating apparatus to eliminate the supporting unit included in the composite body based on a preset manner to obtain the target part:

7. The parts printing method as claimed in claim 6,

controlling a processing apparatus to perform a surface treatment on the target part according to the second material, including: controlling the processing equipment to perform oil coating processing, paint spraying processing, bluing processing and/or film coating processing on the target part according to the second material;

8. A parts printing apparatus, assembled to a printing system including a printing device and an erasing device, the apparatus comprising:

9. A printing system, comprising:

one or more processors;

storage means for storing one or more programs;

when executed by the one or more processors, cause the one or more processors to implement a parts printing method as claimed in any one of claims 1-7.

10. A storage medium containing computer-executable instructions for performing the parts printing method as claimed in any one of claims 1-7 when executed by a computer processor.
