Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods to mitigate the lamination effect in 3D printing, such as reducing layer thickness or establishing surface texture features, are either limited in scope or require professional knowledge, making it difficult for non-experts to effectively address the issue.
Innovation Solution
A 3D printing slicing method that involves acquiring a 3D model and a target texture picture, preprocessing them to establish a mapping set, slicing the model with a slice plane to find intersection points, and revising coordinates based on pixel values to generate outer contour points, thereby creating an outer contour boundary line that simulates the target texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If layer thickness is reduced to improve surface accuracy, then manufacturing precision is improved, but productivity deteriorates due to increased printing time and layers
Solution Approach 1:
The patent changes the parameter of layer thickness dynamically by adjusting the Z-coordinate of slice planes based on surface texture features. For inclined planes and curved surfaces, the slice plane is tilted or positioned at optimal angles to reduce apparent layer thickness in critical areas while maintaining standard thickness elsewhere, thus improving surface accuracy without proportionally increasing total printing time
Solution Approach 2:
The slice plane is made dynamic by allowing its orientation and position to vary across different regions of the model. The system calculates optimal slice plane angles based on surface normals and texture requirements, enabling adaptive layer thickness adjustment that responds to local geometric features rather than applying a uniform layer thickness throughout the entire model
2Manufacturing precision
If surface texture features are established to reduce lamination effect, then manufacturing precision is improved, but device complexity increases due to professional modeling requirements
Solution Approach 1:
The system performs self-service by automatically generating surface texture features through algorithmic processing of the 3D model geometry. The slice plane calculation and texture feature extraction are performed automatically based on mathematical models of surface normals, curvature, and desired texture patterns, eliminating the need for manual professional modeling operations
Solution Approach 2:
The patent replaces manual modeling operations with computational algorithms. Instead of requiring users to manually create surface texture features through complex modeling tools, the system uses automated calculations based on surface geometry, slice plane orientations, and texture parameter specifications to generate the desired surface features programmatically
3Manufacturing precision
If professional surface texture modeling is applied, then manufacturing precision is improved, but ease of operation deteriorates due to limited accessibility
Solution Approach 1:
The system uses 2D texture images as simplified copies or representations of desired surface features. Instead of requiring users to create complex 3D surface models, they can apply 2D texture images that are then mapped onto the 3D model surface through the slicing process, dramatically simplifying the operation while maintaining surface texture quality
Solution Approach 2:
The patent transitions from 3D surface modeling operations to 2D texture image application. By allowing users to work with 2D images that are projected and integrated into the 3D slicing process, the system reduces the dimensional complexity of user interaction while preserving the ability to create high-quality surface textures on the final printed object
