STL File Object Splitting for Copyright Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies face challenges in asserting copyright for individual components within a combined 3D model represented by an STL file, as existing registration systems only recognize the copyright of the combined subject, making it difficult to protect against illegal piracy of individual object shapes.
Innovation Solution
A method and apparatus for automatically splitting an STL file into individual objects by tagging and classifying vertex coordinates, allowing for the generation of separate STL files for each object, enabling accurate registration and protection of each component's copyright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an STL plan representing a combined subject is registered with a copyright registration system, then the copyright of the combined subject is recognized, but the copyright of each individual object cannot be asserted
Solution Approach 1:
The patent segments the combined 3D model into individual object components by identifying disconnected components in the STL file. Each component is separated and registered independently, allowing copyright protection for both the combined subject and individual objects. This segmentation enables the system to maintain information about each component while preserving the overall combined subject registration.
2Reliability
If manual splitting of STL plans is performed to protect individual object copyrights, then individual object copyright can be asserted, but the process becomes complex and time-consuming
Solution Approach 1:
The system performs automatic component separation by analyzing the STL file data structure and identifying disconnected components through algorithmic processing. This self-service approach eliminates the need for manual intervention in splitting the 3D model, reducing complexity while maintaining accurate separation of individual objects for copyright registration.
Solution Approach 2:
The patent replaces manual mechanical splitting processes with automated computational algorithms that process STL file data. The system uses computer-based methods to identify, separate, and register individual components, substituting human manual operations with automated digital processing to reduce complexity and improve efficiency.
3Reliability
If manual splitting of STL plans is performed, then individual object copyright can be protected, but the process requires significant time and effort
Solution Approach 1:
The system automatically performs component separation by processing STL file data through algorithms that identify disconnected components. This automation eliminates time-consuming manual operations, allowing the system to quickly separate and register individual objects while maintaining accurate copyright protection for each component.
Solution Approach 2:
The system performs preliminary automatic separation of components during the registration process itself, rather than requiring separate manual splitting operations. By integrating the component identification and separation into the initial registration workflow, the system eliminates additional time requirements while ensuring individual object copyright protection is established from the outset.

AI summary
Provided are a method and apparatus for automatically splitting an object and a method, apparatus, and system for registering a file. The method for splitting an object includes receiving the data of a stereolithography (STL) file representing a 3D image, tagging vertex coordinates corresponding to objects included in the 3D image so that the vertex coordinates are classified for each object, and splitting each of the objects included in the 3D image based on the tagged vertex coordinates.
