3D Shaping Data Selection for Targeted Test Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing three-dimensional shaped objects, particularly large-sized ones, face inefficiencies such as prolonged shaping times and excessive material usage due to the need to shape unnecessary parts during test shaping.
Innovation Solution
A method involving the acquisition of shape and shaping data, display of the object on a designated region, and selective data generation for targeted shaping, allowing only the designated region to be shaped, thereby optimizing material usage and reducing unnecessary shaping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire three-dimensional shaped object is shaped during test shaping, then the actual shaping state can be checked, but the shaping time becomes long and the amount of shaping material used becomes large
Solution Approach 1:
The patent divides the three-dimensional shaped object into multiple regions (target region and non-target region) and selectively shapes only the target region during test shaping. This segmentation allows verification of shaping state in critical areas without processing the entire object, thereby reducing shaping time and material consumption while maintaining checking accuracy.
Solution Approach 2:
The patent applies different processing strategies to different regions of the object. The target region, which requires verification, is shaped with full precision, while the non-target region is excluded from shaping. This local differentiation ensures that quality checking is performed where needed without wasting resources on areas that don't require verification.
2Reliability
If the entire three-dimensional shaped object is shaped during test shaping, then the actual shaping state can be checked, but the amount of shaping material used becomes large
Solution Approach 1:
The patent segments the object into target and non-target regions, shaping only the target region during test shaping. This reduces the volume of material consumed while still enabling verification of the shaping state in critical areas through selective processing.
Solution Approach 2:
The patent implements region-specific processing where only the target region requiring verification is shaped with full material application, while the non-target region is excluded. This local quality approach minimizes material consumption while maintaining the ability to check shaping accuracy where it matters.
3Productivity
If selective shaping of target region is performed, then shaping time is reduced and material consumption is reduced, but the system requires region designation and data selection capabilities
Solution Approach 1:
The patent performs preliminary actions by pre-defining the target region and generating corresponding shaping data before the actual shaping process. The region designation and data selection are completed in advance, allowing the shaping system to simply execute the pre-prepared selective shaping without requiring complex real-time decision-making, thus balancing productivity improvement with acceptable system complexity.

AI summary
A method for producing a three-dimensional shaped object includes a first acquisition step for acquiring first shape data representing a three-dimensional shape of the three-dimensional shaped object and first shaping data that is generated on the basis of the first shape data and that is for shaping the three-dimensional shaped object; a first display step for displaying the three-dimensional shaped object on a display section based on the first shape data; a determination step for determining a target region of the three-dimensional shaped object that is displayed on the display section based on a designation region that designates a range in three-dimensional space; a second acquisition step for selecting data of a portion corresponding to the target region in the first shaping data and acquiring second shaping data; and a shaping step, based on the second shaping data, for performing three-dimensional shaping to stack layers by discharging shaping material from a discharge section toward a stage.
