3D Object Certification via Printer State Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to determine whether a 3D object was generated by a 3D printer that was in an intended state, ensuring the object's quality and properties, especially after repairs, upgrades, or modifications, as the printer's state may deviate from its original intended configuration.
Innovation Solution
A method to certify 3D objects involves obtaining printer state data and intended state data, comparing them to determine compliance, using databases or distributed ledgers like blockchain to secure and validate the certification process, ensuring the printer was in an acceptable state at the time of object generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the 3D printer undergoes repairs, upgrades, or modifications to improve functionality or fix issues, then the printer's performance and adaptability are improved, but the printer's state may deviate from its original intended configuration, compromising the reliability and quality assurance of printed objects
Solution Approach 1:
The system performs preliminary actions by recording the intended state data of the 3D printer before any repairs, upgrades, or modifications occur. This recorded state serves as a reference baseline against which the current printer state can be compared later to determine compliance and maintain quality assurance.
Solution Approach 2:
The system implements feedback by continuously monitoring and comparing the current printer state data against the recorded intended state data. This feedback mechanism determines whether the printer remains in compliance with its intended configuration, enabling quality assurance even after modifications.
2Manufacturing precision
If the printer state is strictly maintained to ensure object quality, then the reliability and manufacturing precision are improved, but the ease of repair and adaptability are reduced
Solution Approach 1:
The system records the intended state data before repairs or modifications, creating a reference point that allows the printer to be restored or verified against its original configuration. This enables repairs to be performed more easily while maintaining the ability to ensure object quality through state comparison.
3Measurement precision
If comprehensive state data is collected and verified to ensure compliance, then the measurement precision and reliability are improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The system extracts and separates the critical state data (firmware versions, component configurations) into distinct recorded intended state records. This extraction allows for focused verification of specific parameters without requiring complex processing of all possible printer data, simplifying the overall system while maintaining measurement precision.

AI summary
According to an example, a method to certify 3D objects comprises receiving a request to certify a 3D object printed by a 3D printer, obtaining printer state data relating to a recorded state of the 3D printer and intended state data relating to an intended state of the 3D printer at a time when the 3D object was printed, determining if the recorded state of the 3D printer is in compliance with the intended state of the 3D printer, and approving the request to certify the 3D object if the recorded state is determined to be in compliance with the intended state.
