3D Product Support Frames for Protected Post-Processing Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies face challenges in efficiently facilitating post-processing operations such as unpacking, cleaning, and packaging of 3D printed products due to the lack of effective support structures that allow for limited movement and protection while enabling access to hard-to-reach areas.
Innovation Solution
The development of 3D production support frames that provide non-rigid support, are self-supporting, and include features like flexible cushioning, handles, vacuum plates, and quality control indicators, enabling automated processing and robotic handling, while conforming to standardized geometries for batch processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid support structures are used to protect 3D printed products, then protection is improved, but accessibility to hard-to-reach areas deteriorates
Solution Approach 1:
The support frame incorporates flexible elements that allow dynamic adjustment of rigidity. The frame can be rigid when needed for protection and flexible when needed for accessibility, adapting its mechanical properties based on operational requirements.
Solution Approach 2:
The support frame uses flexible cushioning portions and thin-walled structures that provide protection while allowing access to hard-to-reach areas. These flexible elements can deform to accommodate cleaning tools and inspection devices while still providing structural support.
2Stability of the object's composition
If fixed support structures are used to stabilize products, then stability is improved, but movement freedom deteriorates
Solution Approach 1:
The support frame transitions from fixed to movable configurations based on operational needs. During printing, the frame provides stable fixed support; during post-processing, it allows controlled movement and repositioning of the printed object.
Solution Approach 2:
The support frame is divided into modular segments that can be independently adjusted or reconfigured. This segmentation allows parts of the frame to remain fixed for stability while other segments provide movement freedom for accessibility.
3Adaptability or versatility
If custom support structures are designed for each product, then product-specific support is improved, but manufacturing complexity deteriorates
Solution Approach 1:
The support frame is designed as a universal multi-functional structure that can accommodate various 3D printed products through standardized interfaces and adjustable components. A single frame design serves multiple functions: supporting during printing, facilitating post-processing, and enabling packaging.
Solution Approach 2:
The support frame uses adjustable parameters such as flexible element stiffness, support arm positioning, and cushioning density to adapt to different product requirements without requiring custom design for each product. These parameter adjustments allow the same basic structure to serve multiple product types.
4Productivity
If automated processing features are added to support frames, then productivity is improved, but device complexity deteriorates
Solution Approach 1:
The support frame incorporates self-service features such as automatic alignment mechanisms, self-adjusting flexible elements, and integrated quality control indicators that reduce the need for complex external automation systems while still enabling automated processing.
Solution Approach 2:
Multiple functions are merged into the support frame structure itself: support during printing, handling during post-processing, quality indication, and packaging preparation. This integration reduces the need for separate automated devices for each function.

AI summary
An example system includes an object and a support frame supporting the object. The support frame constrains movement of the object relative to the support frame, and the support frame includes at least one of a cage or a shackle to non-rigidly constrain movement of at least a part of the object.
