Abstract
A 3D printing device and a resume printing method thereof are provided. The method includes: executing printing commands sequentially to control a print head for printing; obtaining a first printing command executed when a printing interruption occurs, and resuming printing according to the first printing command.
Claims10
A resume printing method, adapted for a three-dimensional (3D) printing device, comprising:
- executing a plurality of printing commands sequentially to control a print head of the 3D printing device for printing;
- adding a count value by 1 when a printing command is executed;
- periodically recording the count value in a non-volatile memory according to a predetermined cycle;
- and
- when a printing interruption occurs, obtaining a first printing command executed while the printing interruption occurs and resuming printing according to the first printing command,
- wherein the step of resuming printing according to the first printing command comprises:
- when the printing interruption occurs, reading the count value stored in the non-volatile memory to obtain the first printing command corresponding to the count value and obtain a time period from a time when the 3D printing device started executing the first printing command to a time when the printing interruption occurred;
- calculating an interruption position when the printing interruption occurred according to the first printing command, a second printing command executed before the first printing command and the time period;
- and
- resuming printing from the interruption position according to the first printing command.

A 3D printing device, comprising:
- a print head;
- a controller, coupled to the print head and configured to execute a plurality of printing commands sequentially to control the print head for printing;
- and
- a non-volatile memory, coupled to the controller and configured to periodically record a count value according to a predetermined cycle,
- wherein the controller, when a printing interruption occurs, is configured to:
- read the count value stored in the non-volatile memory to obtain the first printing command, which is executed when the printing interruption occurred;
- obtain a time period from a time when the 3D printing device started executing the first printing command to a time when the printing interruption occurred;
- calculate an interruption position when the printing interruption occurred according to the first printing command, a second printing command executed before the first printing command and the time period;
- and
- control the print head to resume printing from the interruption position according to the first printing command.
