Layer Quality Barcode Visualization for Additive Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Additive manufacturing processes, such as powder bed fusion, face challenges with powder spread, exposure, and recoating issues, leading to low robustness and requiring extensive time to produce objects composed of thousands of layers, where overall quality is often affected by minor quality issues in multiple layers rather than single faulty layers.
Innovation Solution
A method and apparatus for computer-aided processing of quality information in additive manufacturing systems, which involves receiving quality indicators for each printed layer, assigning colors based on these indicators, and visualizing them as a sequence of colored bars to create a 'health barcode' for quick identification of quality issues, allowing for immediate feedback and adaptive manufacturing adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If quality indicators for each layer are monitored and analyzed in detail, then manufacturing precision and reliability are improved, but loss of time increases due to the extensive number of layers requiring evaluation
Solution Approach 1:
The patent segments the quality evaluation process by dividing the object into individual layers, each assigned a quality indicator. This segmentation allows parallel processing of quality assessment across multiple layers simultaneously, reducing the total evaluation time while maintaining comprehensive quality monitoring of all layers
Solution Approach 2:
The patent uses color-coded visual indicators to represent quality levels of different layers. Each layer is displayed with a color corresponding to its quality indicator, enabling operators to rapidly assess the quality status of thousands of layers at a glance without manually analyzing each layer's data, thus dramatically reducing evaluation time while preserving precision
2Manufacturing precision
If the number of layers is increased to achieve higher manufacturing precision, then manufacturing precision is improved, but productivity decreases due to the extended printing time required
Solution Approach 1:
The patent implements real-time feedback by continuously monitoring quality indicators during the printing process and providing immediate visual feedback through the color-coded display. This allows for adaptive adjustments to be made during printing, ensuring high quality standards are maintained across all layers without requiring post-printing inspection, thereby preserving productivity while achieving high manufacturing precision
Solution Approach 2:
The patent performs preliminary quality assessment and visualization during the printing process itself, rather than after completion. By evaluating and displaying quality indicators layer-by-layer as printing progresses, the system enables early detection of quality issues and immediate corrective actions, preventing waste of time and resources on defective objects while maintaining high printing speeds

AI summary
Provided is a method for computer-aided processing of quality information of an object manufactured by stacked printed layers in an additive manufacturing system, including the steps of: receiving a quality indicator for each printed layer of the object from the manufacturing system, assigning a color out of a predefined set of colors to each quality indicator depending on the value of the quality indicator, visualizing the quality indicators of the received manufactured layers as a sequence of colored bars ordered according to the sequence of the manufactured layers the color of each bar indicating the value of the quality indicator of the respective printed layer on a graphical user interface.
