Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing methods struggle with the lamination effect, particularly on inclined planes, where reducing layer thickness improves accuracy but is not feasible for non-professionals, and establishing surface texture features is complex and limited in scope.
Innovation Solution
A 3D printing slicing method that involves acquiring a 3D model and a target texture picture, preprocessing to establish a mapping set between the model and picture, slicing layers, and revising intersection points based on pixel values to create outer contour boundary lines, allowing for improved texture simulation without complex modeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If layer thickness is reduced to improve surface accuracy, then manufacturing precision is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent applies preliminary action by pre-processing the 3D model to add surface texture features before slicing. The method includes loading the model, performing surface analysis to identify inclined planes, adding texture features to these surfaces, and then proceeding with slicing. This preliminary modification of the model's surface properties allows standard slicing parameters to produce better surface quality without requiring reduced layer thickness, thus resolving the contradiction between manufacturing precision and device complexity.
2Manufacturing precision
If surface texture features are established to reduce lamination effect, then manufacturing precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent implements self-service by enabling the slicing software to automatically perform surface analysis and texture feature addition without requiring user expertise in 3D modeling. The system autonomously identifies inclined planes and other surfaces benefiting from texture features, applies appropriate textures, and generates the modified model for printing. This automation eliminates the need for professionals to manually model texture features, significantly improving ease of manufacture while maintaining manufacturing precision.
3Manufacturing precision
If professional modeling knowledge is required to establish surface texture features, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical/manual process of professional modeling with an automated computational system. Instead of requiring users to manually create surface texture features through complex 3D modeling operations, the system uses algorithms to automatically analyze the model geometry, identify surfaces requiring texture enhancement, and apply appropriate textures programmatically. This substitution of automated computation for manual modeling operations maintains manufacturing precision while dramatically improving ease of operation for non-professionals.
