Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3D printing, large build platforms face challenges with debris generated during the printing process, which can compromise the performance of energy beams by cross-contamination, leading to reduced accuracy and power, and require extensive setup times due to the need for multiple energy beams to cover the target surface effectively.
Innovation Solution
A 3D printing system with a dynamically movable optical system and translation mechanism that minimizes debris cross-contamination between energy beams by allowing them to translate and position optimally relative to the build platform, ensuring high-fidelity printing with reduced setup times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple stationary energy beams are used to cover a large target surface, then the coverage area is improved, but debris cross-contamination between beams increases and setup time increases
Solution Approach 1:
The patent implements a dynamically movable optical system where energy beams can translate and reposition themselves relative to the build platform. This dynamic capability allows the system to maintain optimal positioning while covering large target surfaces, reducing debris cross-contamination between beams while preserving comprehensive coverage area.
2Area of stationary object
If multiple stationary energy beams are used to cover a large target surface, then the coverage area is improved, but setup time increases
Solution Approach 1:
The movable optical system eliminates the need for extensive setup of multiple stationary beams by enabling dynamic repositioning. The system can adaptively cover large target surfaces through movement rather than requiring pre-configured multiple fixed beams, significantly reducing setup time while maintaining comprehensive coverage.
3Device complexity
If energy beams are made stationary to simplify the system, then device complexity is reduced, but debris cross-contamination and loss of accuracy increase
Solution Approach 1:
The patent employs a movable optical system that dynamically adjusts beam positions to minimize debris exposure and maintain accuracy. This dynamic approach preserves manufacturing precision by allowing real-time adaptation to debris conditions without requiring overly complex stationary multi-beam configurations.
