Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing three-dimensional molding methods, the part to be produced, support material, and test piece are molded separately, leading to inefficient use of powder and inability to achieve efficient molding.
Innovation Solution
A three-dimensional molding method where the part to be produced and a test piece are molded in the same step, with the test piece either supporting the part or integrated with the support material, allowing for efficient powder utilization and reduced sintering strength requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the part to be produced, support material, and test piece are molded separately in independently isolated states, then each component can be molded with dedicated attention to its specific requirements, but the molding process becomes inefficient and powder utilization is wasted
Solution Approach 1:
The patent combines the molding of the part to be produced, support material, and test piece into a single integrated molding process. The test piece is positioned to contact or be close to the support material, allowing all components to be molded simultaneously in the same powder bed, thereby improving molding efficiency and powder utilization while maintaining quality through unified process control
2Manufacturing precision
If the test piece is molded in an independently isolated state from the part to be produced and support material, then the test piece can be molded with focused attention on its testing requirements, but powder utilization becomes inefficient
Solution Approach 1:
The patent merges the test piece molding with the part and support material molding by positioning the test piece to contact or be close to the support material within the same powder bed. This integrated approach allows all components to share the same powder material, eliminating the need for separate powder beds and significantly reducing powder waste
3Adaptability or versatility
If separate molding is used for the part to be produced and test piece, then each can be optimized for its specific function, but the overall process complexity increases
Solution Approach 1:
The patent combines multiple molding operations into a single integrated process where the part to be produced, support material, and test piece are all molded simultaneously in the same powder bed. This reduces process complexity by eliminating separate molding steps while maintaining functional optimization through appropriate positioning and design of each component within the unified structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method enables faster, more efficient molding by shortening the distance between the test piece and support material, conserving powder, and simplifying the design by eliminating the need for separate support materials, while ensuring the test piece provides adequate support.
Implementation Method 1
sintering of the powder by irradiation of a laser beam or an electron beam
Implementation Method 2
sintering of the powder by irradiation of a laser beam or an electron beam
