Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing three-dimensional modeling objects do not effectively address the issue of ensuring uniform temperature distribution and adhesion strength between stacked layers, leading to inconsistencies in the quality of the final product.
Innovation Solution
A method involving temperature measurement, prediction, and data generation/correction steps to control the stacking of modeling material based on temperature distribution, ensuring the material is applied to regions of varying temperatures in a manner that enhances adhesion strength between layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional layer stacking method is used without temperature control, then manufacturing process is simple, but adhesion strength between layers is inconsistent
Solution Approach 1:
The patent measures the temperature distribution of the n-th layer before stacking the n+1-th layer, and predicts the temperature distribution in advance. This preliminary temperature assessment allows the system to plan the stacking path beforehand, ensuring optimal adhesion conditions are met before material deposition occurs.
Solution Approach 2:
The patent identifies first regions (lower temperature) and second regions (higher temperature) within the n-th layer, and applies different stacking strategies to each region. The ejection unit prioritizes stacking material in lower temperature regions first, then proceeds to higher temperature regions, creating locally optimized adhesion conditions throughout the layer.
2Temperature
If temperature distribution is not considered during stacking, then stacking speed is high, but temperature uniformity across layers is poor
Solution Approach 1:
The system predicts the temperature distribution of the n-th layer before stacking begins, allowing the ejection unit to plan its path in advance to address temperature non-uniformities proactively rather than reactively during the stacking process.
Solution Approach 2:
The patent modifies the stacking parameters dynamically based on temperature conditions. The ejection unit changes its stacking sequence and positioning based on the identified temperature regions, adjusting where and how material is deposited to achieve more uniform temperature distribution across the layered structure.
3Strength
If layers are stacked without considering temperature distribution, then manufacturing process is simple, but adhesion strength varies across XY plane
Solution Approach 1:
The patent divides the n-th layer into distinct temperature zones (first regions with lower temperature and second regions with higher temperature) and applies region-specific stacking strategies. This local differentiation ensures that each area receives material under optimal temperature conditions for adhesion, resulting in uniform adhesion strength across the entire XY plane.
Solution Approach 2:
The system measures the actual temperature distribution of the n-th layer and uses this feedback information to determine the stacking path for the n+1-th layer. This closed-loop approach ensures that stacking decisions are based on real temperature conditions, compensating for variations and achieving consistent adhesion across different regions.

AI summary
A method of manufacturing a three-dimensional modeling object includes a first stacking step for stacking an n-th layer, at least one step of a temperature measurement step for measuring a temperature distribution of the n-th layer and a temperature prediction step for predicting a temperature distribution of the n-th layer, a data generation step for generating or correcting the modeling data relating to an n+1-th layer, based on the temperature distribution of the n-th layer, and a second stacking step for stacking the n+1-th layer, based on the modeling data that relates to the n+1-th layer, wherein the n-th layer includes a first region and a second region, the first region is a region having a temperature lower than the second region, and, in the data generation step, the modeling data relating to the n+1-th layer is generated or corrected.
