20150312119 | SYSTEM FOR THE NETWORK MONITORING OF 3D PRINTING AND METHOD THEREOF - Monitoring a 3D printer comprises a network information module, a photographic device, a status report module, and a fixed format instruction receiver module. The photographic device is capable of periodically shooting a print status of the 3D printer. The status report module is capable of periodically reporting the print status or instantly reporting a print error of the 3D printer. The fixed format instruction receiver module is capable of receiving a remote fixed format instruction to operate the 3D printer. Thus, the system may not require an operator to monitor the 3D printer for long. Even on the remote end, the system can monitor a print status of a printed object and may execute a corresponding treatment when a print error of the 3D printer has occurred. | 10-29-2015 |
20150314533 | PRINTING METHOD FOR THREE-DIMENSIONAL OBJECT AND SYSTEM THEREOF - A printing method for a three-dimensional object and system thereof, the method includes: analyze and build a three-dimensional model of a work piece to be printed. Discrete three-dimensional model along the first axis into the two-dimensional multi-level, and get a second two-dimensional plane coordinate for the second axis and the third axis from each layer in two-dimensional layer.
