Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional printing technologies using bottom-up SLA face issues with the structural rigidity and strength of printed objects due to the soft nature of photocurable materials, leading to deformation and cracking, which affects the fineness and success rate of the finished products.
Innovation Solution
A three-dimensional printing apparatus equipped with a heat dissipation assembly that either directly or indirectly cools the printed object, improving its structural rigidity and strength by reducing temperature, thereby enhancing the printing process's success rate and product fineness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If photocurable material is used for three-dimensional printing, then fine finished-products can be made, but the printed object lacks structural rigidity and strength causing deformation or cracking
Solution Approach 1:
The patent applies parameter changes by controlling the temperature of the printed object during the printing process. Specifically, the system maintains the printed object at a lower temperature (e.g., 25°C or below) to increase its structural rigidity and strength, preventing deformation and cracking while still achieving fine finished-products through the photocurable material curing process.
2Ease of manufacture
If photocurable material is cured layer by layer, then three-dimensional printed objects can be formed, but the soft material causes deformation under stress during printing
Solution Approach 1:
The patent uses parameter changes by controlling temperature to stabilize the printed object's structure. The heat dissipation assembly maintains the object at a lower temperature throughout the layer-by-layer curing process, providing structural stability and preventing deformation under stress while enabling the printing process to proceed.
Solution Approach 2:
The patent applies preliminary action by pre-cooling the printed object before and during the curing process. The heat dissipation assembly is activated before printing begins and continues to cool the object during printing, preparing the material in advance to withstand stresses during the manufacturing process.
