3D Printed Support Separation for Multi-Object Base Plate Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In additive manufacturing, multiple objects molded on a base plate simultaneously risk damage during separation due to contact with each other when trying to be removed from the base plate, as existing methods lack effective support structures to maintain object separation and prevent mutual contact.
Innovation Solution
A three-dimensional object manufacturing method involving the use of additive manufacturing to mold first and second three-dimensional objects and support parts at different positions on a base plate, where the objects are separated by dividing the support parts after one object is removed from the base plate, ensuring an interval between them to prevent contact and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple objects are molded on a base plate at once, then manufacturing efficiency is improved, but objects may contact each other and be damaged during separation
Solution Approach 1:
A support part is introduced as an intermediary structure between multiple objects on the base plate. This support part maintains spatial separation between objects during the additive manufacturing process and enables safe separation by providing a structural framework that prevents direct contact between objects when they are removed from the base plate
Solution Approach 2:
The support structure is divided into multiple support parts, each associated with specific objects. This segmentation allows independent separation of different object groups while maintaining overall structural integrity during the manufacturing and separation processes
2Device complexity
If objects are separated directly from the base plate without support structures, then the separation process is simpler, but objects may deform or collapse due to lack of support
Solution Approach 1:
Support parts are pre-formed together with the objects during the additive manufacturing process before separation occurs. This preliminary formation of the support structure ensures that objects maintain their dimensional accuracy and structural integrity throughout the manufacturing process and during subsequent separation operations

AI summary
A three-dimensional object manufacturing method includes a molding step of molding a first three-dimensional object, a second three-dimensional object and a first support part for coupling the first and second three-dimensional objects at mutually different positions on a base plate by an additive manufacturing, and a separation step of separating the first three-dimensional object, the second three-dimensional object, the first support part and the base plate from each other. In the separation step, the first and second three-dimensional objects are separated from each other by dividing the first support part after at least one of the first and second three-dimensional objects is separated from the base plate.
