A 3DP equipment processing monitoring method according to claim 4, characterized in that: When the data is abnormal, corresponding processing is performed based on the processing method, which also includes: receiving the second state data, and comparing the second state data with the printing parameter to obtain a third comparison deviation; When the third contrast deviation is less than or equal to a fourth threshold, a third adjustment parameter is generated based on the processing method and sent to the powder spreading device for corresponding processing; When the third comparison deviation is greater than a fourth threshold, a second prompt message is sent, and if there is no response within a predetermined time, a second pause signal is sent to suspend processing; When the third comparison deviation is greater than the fifth threshold, a second termination signal is sent to terminate the processing and a second warning message is sent.

8. A computer device, characterized in that: It includes a processor, a communication interface, a memory and a communication bus, wherein the processor, the communication interface and the memory communicate with each other via the communication bus; Memory, used to store computer programs; The processor, when used to execute the program stored in the memory, can implement a 3DP equipment processing process monitoring method as described in any one of claims 4-7.
