Thermal Device Segmentation for 3D Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for producing three-dimensional shaped products using metal or non-metal powders sintered by electromagnetic waves face inefficiencies in heating and cooling due to the integration of heating or cooling devices directly onto the table, leading to reduced thermal efficiency and difficulty in removing fully shaped objects.
Innovation Solution
The heating or cooling devices, comprising heating or cooling pipes, are extended laterally and firmly fixed to a frame body or supporting rod above the table, creating a vertical space to prevent thermal conduction and allow for efficient heating or cooling, while also enabling easy discharge of unsintered powder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the heating device or cooling device is integrated into the table, then the table can be stably supported, but the thermal efficiency is reduced due to unnecessary thermal conduction
Solution Approach 1:
The heating device or cooling device is segmented from the table structure. Instead of being integrated into the table, the device is separated and supported by independent supports that are firmly fixed to the floor or ground, allowing the table to be removed or moved without the thermal device.
Solution Approach 2:
The heating device or cooling device is extracted from the table structure. The device is taken out and positioned separately with its own support system, eliminating the thermal conduction path through the table while maintaining the device's functionality.
2Ease of operation
If the heating device or cooling device is firmly fixed to the table, then the table remains stable, but the fully shaped object cannot be easily removed from the table
Solution Approach 1:
The support system for the heating/cooling device is segmented from the table structure. Independent supports are firmly fixed to the floor/ground, while the table remains separate and removable, allowing easy object removal while maintaining device stability.
Solution Approach 2:
The heating device or cooling device is extracted from the table structure and supported independently. This allows the table to be freely removed or adjusted without being constrained by the thermal device, facilitating easy object removal.
3Loss of energy
If the table is cooled or unnecessarily cooled, then the table temperature is controlled, but the cooling efficiency is reduced
Solution Approach 1:
The cooling device is segmented from the table structure and supported independently. This prevents unnecessary cooling of the table while allowing targeted cooling at the work position, improving cooling efficiency and reducing energy waste.
Solution Approach 2:
The cooling device is extracted from the table and positioned separately with independent support. This allows the cooling function to be applied only where needed without unnecessarily cooling the entire table, thereby improving cooling efficiency.
