3D Printer DRM for Controlled Design Distribution and Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printing systems lack effective protection against unauthorized copying and redistribution of digital design files, allowing for piracy and undermining the intellectual property rights of designers.
Innovation Solution
A system and method that utilizes a print card or unique 3D printer configuration to control the printing of 3D designs by limiting the number of prints or time period, ensuring the source code is protected and deleted after use, and allowing for secure distribution through an app store.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 3D design files are made freely downloadable, then accessibility and ease of operation improve, but intellectual property protection deteriorates due to unauthorized copying and redistribution
Solution Approach 1:
The patent introduces a licensing server as an intermediary between the 3D design repository and the 3D printer. The licensing server receives print requests, validates licenses, and controls the transfer of design data to authorized printers only. This mediator enables free downloadability while preventing unauthorized copying by intercepting and controlling all data transfer operations through license verification.
Solution Approach 2:
The system creates controlled copies of 3D design files through a licensing mechanism. When a user purchases a license, the system generates an authorized copy that can be transferred to specific 3D printers. The original master copy remains secured on the repository server, and the licensed copy includes embedded authentication data that prevents further unauthorized reproduction, thus enabling distribution while protecting against piracy.
2Object-affected harmful factors
If DRM protection is implemented to prevent piracy, then intellectual property protection improves, but device complexity and ease of operation worsen
Solution Approach 1:
The licensing server performs multiple functions within a single system: it stores license information, validates authentication data, controls file transfer permissions, and manages printer authorization. By consolidating these DRM functions into one multi-functional server rather than distributing complex protection mechanisms across multiple components, the system achieves effective piracy prevention while minimizing overall device complexity.
3Object-affected harmful factors
If purchase limits are imposed on 3D design downloads, then intellectual property protection improves, but productivity and ease of operation deteriorate
Solution Approach 1:
The system performs license validation and authorization checks in advance before any printing operation begins. When a user initiates a print request, the licensing server pre-verifies the license status, printer authorization, and usage limits. This preliminary action ensures that authorized printing proceeds without interruption, maintaining high productivity while still enforcing purchase limits and preventing unauthorized redistribution.
Data Source
AI summary
A 3D printing system provides digital rights management protecting proprietary source code defining 3-D object data usable to print 3-D objects from uncompensated printing, and includes a central server, 3D printers, and corresponding single board computers (SBCs) each coupled to a respective printer. The central server stores the proprietary source code, permits displaying of an inventory of designs in an online store, and permits a user to securely purchase use of the source code to print one or more copies of a desired 3D object. The central server communicates across a network to incrementally stream the digital file containing the proprietary source code defining the desired 3D object to an SBC, and selectively controls each SBC/printer, to cause deletion of each incrementally streamed plurality of slices when the purchased use is completed. The SBC notifies the central server when the purchased use is completed.
