3D Printer Batch Printing Failure Recovery via Model Skipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3D printing, when a model fails to be printed, the 3D printer continues to extrude material, wasting time and material, and can cause extruded material to smear onto other parts, compromising their appearance and shape.
Innovation Solution
A method and apparatus for a 3D printer that allows users to select which models to skip printing through a user interface, using a one-to-one correspondence between model identifiers and pixel regions in an image, enabling the printer to execute a strategy that skips printing the selected models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the 3D printer continues to extrude material after a model printing failure, then the printing process can be completed without interruption, but material is wasted and extruded material smears onto other parts
Solution Approach 1:
The system monitors the printing process in real-time and detects failures. When a failure is detected for a specific model, the system provides feedback to the control unit, which then adjusts the printing plan to skip the failed model and continue with remaining models, preventing material waste and smear while maintaining overall productivity
Solution Approach 2:
The printing plan is made dynamic and adaptable. Instead of rigidly following the original printing sequence, the system dynamically adjusts the plan based on real-time failure detection, allowing selective skipping of failed models while continuing to print successful models, thus balancing continuity with resource efficiency
2Productivity
If the 3D printer continues to extrude material after a model printing failure, then the printing process can be completed without interruption, but the appearance and shape of other parts are compromised
Solution Approach 1:
The system detects printing failures in real-time and provides feedback to modify the printing plan. When a model fails to print properly, the system skips extruding material for that model, preventing smeared material from contaminating other parts and preserving their appearance and shape quality while maintaining overall printing continuity
Solution Approach 2:
The failed model is extracted or removed from the printing sequence. When a model printing failure is detected, the system extracts that specific model from the remaining printing plan, preventing it from causing harm to other models while allowing the printing process to continue uninterrupted for the remaining valid models
3Loss of substance
If users can select models to skip through a user interface, then material waste and smear are prevented, but the device complexity increases
Solution Approach 1:
The system automatically detects printing failures and performs self-service by autonomously adjusting the printing plan to skip failed models. This eliminates the need for complex user interfaces or manual intervention, preventing material waste through automated failure detection and plan modification while keeping the device complexity manageable
Solution Approach 2:
The system implements automated feedback loops that monitor printing status, detect failures, and trigger plan modifications without user intervention. This feedback mechanism prevents material waste and smear automatically, reducing the need for complex user interfaces while maintaining effective control over the printing process

AI summary
A method comprises: acquiring a three-dimensional model file defining multiple models in a batch printing task; establishing a one-to-one correspondence between respective model identifiers of the multiple models and multiple first pixel regions in a first image, wherein the first image is used to display respective graphical representations of the multiple models in a user interface, and each first pixel region is used to display a corresponding graphical representation in the respective graphical representations of the multiple models; and generating, based on the three-dimensional model file, one set of control codes comprising multiple code segments, each code segment comprising control codes for printing a corresponding model in the multiple models and a model identifier of the corresponding model, wherein the one set of control codes is executable by a processor of the 3D printer to enable the 3D printer to execute a printing strategy.
