Solution Overview
Problem
Existing printing systems require extensive processes on the host device, leading to prolonged transfer times and increased load, which can be inefficient and time-consuming.
Innovation Solution
A printing device that includes a discharge head and a printing control section to generate intermediate data based on cross-sectional data from a host device, allowing for the execution of three-dimensional shaping processes independently, thereby reducing the load on the host device and shortening the transfer time of print data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the host device executes extensive processes such as data correction and generates all print data, then the processing capability is centralized and control is simplified, but the transfer time of print data increases and the overall process time is prolonged
Solution Approach 1:
The patent segments the print data generation process into two parts: basic cross-sectional data generation performed by the host device, and intermediate data generation (including color correction and other processes) performed by the printing device itself. This segmentation allows the host device to transmit only essential data while the printing device handles time-consuming processing locally, thereby reducing transfer time while maintaining processing capability.
Solution Approach 2:
The printing device performs intermediate data generation in advance during idle periods or before actual printing operations. By preparing print data locally beforehand, the system reduces the need for extensive real-time data transfer and processing during critical printing operations, thereby shortening overall process time.
2Device complexity
If the host device performs all data correction and processing operations, then centralized control is maintained, but the load on the host device increases and efficiency decreases
Solution Approach 1:
The patent divides the processing workload between the host device and the printing device. The host device handles high-level control and cross-sectional data generation, while the printing device handles intermediate data generation including color correction and other processing operations. This segmentation distributes the computational load, reducing the burden on the host device and improving overall system productivity.
Solution Approach 2:
The printing device is equipped with the capability to perform intermediate data generation and color correction processes independently. By enabling the printing device to serve itself with these processing functions, the system reduces dependency on the host device for every operation, thereby improving efficiency while maintaining coordinated control.

AI summary
A printing device of the present disclosure is used in a printing system including a host device configured to transmit information related to shaping of a three-dimensional object via an electric communication line and executes a three-dimensional shaping process. The printing device includes a discharge head configured to discharge a liquid material for shaping the three-dimensional object, and a printing control section configured to acquire, after the host device generates cross-sectional data of the three-dimensional object, intermediate data based on the cross-sectional data transferred from the host device, generate one or more pieces of print data based on one or more predetermined processes by using the acquired intermediate data, and cause the discharge head to execute the three-dimensional shaping process based on the generated print data.
