3D Mesh Modification for Automatic Design Element Emphasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printing technologies lack the ability to automatically emphasize design elements such as contours, seams, and edges in unicolor concept models, requiring manual highlighting which is cumbersome and time-consuming, especially for models with fine details or large series.
Innovation Solution
A method and system that automatically generates a modified mesh file by identifying target design elements, creating auxiliary meshes based on their geometry, and assigning printing priorities to enhance these elements, allowing for automatic emphasis in the printed 3D object.

Engineering Contradiction Analysis
1Ease of manufacture
If manual highlighting of design lines is performed on 3D printed models, then design elements can be emphasized, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The system enables self-service by automatically identifying and emphasizing design elements without requiring manual intervention. The computer-implemented method autonomously processes the 3D model data to generate a modified mesh file with enhanced design elements, eliminating the need for operators to manually highlight contours, seams, and edges on printed models.
Solution Approach 2:
The invention replaces the mechanical manual process of highlighting design elements with an automated computational system. Instead of physically marking printed models with pens or markers, the system uses software algorithms to process mesh data and generate a modified digital model that automatically emphasizes design elements during the 3D printing process.
2Productivity
If automated methods are implemented to emphasize design elements, then productivity increases, but system complexity increases
Solution Approach 1:
The system achieves universality by implementing a multi-functional computer-implemented method that can handle various design element types (contours, seams, edges) and different 3D model formats through a single integrated process. The method universally processes mesh data to identify and emphasize any design elements based on geometric analysis, eliminating the need for separate tools or manual procedures for different element types.
Solution Approach 2:
The invention uses copying by creating a modified mesh file that replicates the original 3D model geometry while adding emphasis features. The system generates a digital copy of the model with enhanced design elements embedded in the mesh data, which is then used for 3D printing, avoiding the need for physical modifications to the printed object.
3Loss of information
If design elements are automatically emphasized in the mesh file, then visualization of design intent is enhanced, but the processing complexity increases
Solution Approach 1:
The system applies local quality by selectively emphasizing only the specific design elements that require highlighting, rather than uniformly processing the entire model. The method identifies particular geometric features (contours, seams, edges) and applies enhancement only to those locations, preserving the original model's overall structure while improving visibility of critical design intent areas.
Solution Approach 2:
The invention implements preliminary action by performing the design element identification and emphasis process during the digital model preparation stage, before the 3D printing occurs. The system analyzes the mesh data, identifies design elements, and embeds enhancement information in the modified mesh file in advance, so that the design intent is clearly visualized in the printed output without requiring post-processing or manual intervention.
