3D Modeling System for Accurate Object Reproduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When attempting to copy a three-dimensional object modeled by a 3D printer, it is challenging to replicate the object accurately due to the necessity of matching both the 3D model data and specific modeling conditions such as layer pitch, which are difficult to replicate unless the exact conditions are duplicated.
Innovation Solution
A modeling process device and system that includes a scanning unit to gather surface shape information, an accumulation unit to store multiple three-dimensional object information sets, a searching unit to find matching 3D model data, and an extraction unit to identify the modeling conditions used in the original object, allowing for the recreation of the object under the same conditions.

Engineering Contradiction Analysis
1Manufacturing precision
If 3D model data is obtained by three-dimensional measurement and modeling is performed based on this data, then the modeling process can be completed, but the similar object cannot be copied accurately because the modeling conditions (such as layer pitch) are not reproduced
Solution Approach 1:
The system performs preliminary actions by accumulating multiple three-dimensional object information sets including modeling conditions before the copying process. When a copy is requested, the system searches for and retrieves the specific modeling conditions that were used to create the original object, ensuring accurate reproduction without requiring manual re-specification of parameters like layer pitch.
Solution Approach 2:
The system creates a complete copy of the original object's information including not just the 3D model data but also the modeling conditions (layer pitch, modeling machine type, etc.). By storing and retrieving these complete information sets, the system enables accurate replication of the original object's characteristics in the copied version.
2Manufacturing precision
If multiple three-dimensional object information sets are accumulated to enable accurate copying, then copying accuracy improves, but the system complexity increases
Solution Approach 1:
The system merges the accumulation of three-dimensional object information sets with the existing 3D scanning and modeling workflow. By integrating the accumulation unit, searching unit, and extraction unit into the standard 3D modeling process, the system enables accurate copying without requiring separate, complex infrastructure beyond the normal 3D data collection and processing equipment.
