Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing devices using electrochemical additive manufacturing (ECAM) face challenges in achieving fast stacking speed and uniformity, particularly when printing complex shapes, due to inadequate control methods for electrode movement and power supply during the electrochemical deposition process.
Innovation Solution
A 3D printing device with a tub accommodating an electrolyte, a substrate, an electrode module, and a module driver, along with an AD converter and multiple power supplies, is controlled by a main controller to adjust power supply methods dynamically based on stacking height and shape, employing pulse, constant current, or constant voltage power to ensure optimal gap control and efficient printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrochemical deposition method is used for 3D printing metal raw material, then metal stacking is enabled, but stacking speed becomes slow
Solution Approach 1:
The patent implements dynamic gap control where the distance between the electrode module and substrate is continuously adjusted during the electrochemical deposition process. The controller modifies the gap based on real-time deposition conditions to optimize both stacking speed and uniformity, allowing the system to adapt to varying deposition rates and maintain consistent layer quality while improving overall productivity
Solution Approach 2:
The patent changes key process parameters including gap distance, deposition voltage, and current density during the printing process. By dynamically adjusting these parameters, the system optimizes the electrochemical deposition rate while maintaining uniform stacking, thereby resolving the contradiction between fast stacking speed and stacking uniformity
2Productivity
If single power supply method is used for electrochemical deposition, then device complexity is reduced, but printing performance for complex shapes is insufficient
Solution Approach 1:
The patent divides the power supply system into multiple independent power sources, each capable of providing different voltage or current characteristics. This segmentation allows the system to select appropriate power modes for different regions or stages of the deposition process, enhancing printing performance for complex shapes while keeping each individual power unit relatively simple
Solution Approach 2:
The patent designs the power supply system with multi-functionality, where a single power supply unit can operate in multiple modes (constant voltage, constant current, pulsed modes). This universal design enables the system to handle various printing requirements without proportionally increasing device complexity, as one versatile power supply replaces multiple specialized units
