Additive Manufacturing Slicing With Section-Specific Print Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional slicing processes in additive manufacturing are inefficient as they maintain constant print parameters for every layer, failing to optimize different sections of a part, leading to suboptimal manufacturing times and quality.
Innovation Solution
A slicing process that divides a part into multiple sections with unique print parameters, allowing for optimized printing by adjusting parameters for each section and interspersing layers to enhance fusion and manufacturing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If constant print parameters are maintained for every layer, then the slicing process is simple to implement, but manufacturing efficiency and quality are suboptimal
Solution Approach 1:
The patent divides the part into multiple sections, allowing different print parameters to be applied to different sections. This segmentation enables optimized printing for each section while maintaining an organized slicing structure that balances complexity and efficiency.
Solution Approach 2:
The patent applies different print parameters to different sections of the part based on local requirements. Each section can have customized parameters such as layer height, infill density, or printing speed, optimizing quality and efficiency for specific regions without requiring complete reconfiguration.
2Manufacturing precision
If sections are printed separately, then print parameters can be optimized for each section, but manufacturing time increases due to sequential processing
Solution Approach 1:
The patent performs preliminary actions by dividing the part into sections and preparing optimized print parameters for each section before actual printing begins. This pre-planning allows the slicing process to organize sections for efficient printing, reducing overall manufacturing time while maintaining quality.
Solution Approach 2:
The patent enables dynamic printing by allowing the system to switch between different print parameters for different sections during the printing process. This dynamic approach optimizes both quality and time by adapting parameters to local requirements without requiring complete sequential processing of all sections.
