Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current additive manufacturing methods in the construction industry face challenges in integrating reinforcements effectively, particularly with 3D concrete printing, as manual interventions are complex and prone to formwork instability, limiting the widespread adoption of this technology, especially for multi-story structures.
Innovation Solution
A method involving a material output unit that deposits building material in layers along a defined print pathway, with load transfer elements extending into the pathway to stabilize the component and avoid collisions, allowing for the integration of reinforcements without manual intervention, thereby enhancing the stability and process reliability of additively manufactured components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If formwork anchors are used to stabilize the formwork during filling and curing, then the stability of the formwork is improved, but the device complexity and manual work steps increase
Solution Approach 1:
The load transfer elements are automatically pushed out of the print pathway by the material output unit during the additive manufacturing process itself, eliminating the need for separate manual installation of formwork anchors. The system performs its own stabilization function through the interaction between the material output unit and the load transfer elements.
Solution Approach 2:
The stabilization function is merged into the additive manufacturing process by integrating the load transfer elements directly into the component being manufactured. The load transfer elements serve dual purposes: reinforcing the component structure and providing formwork stability during manufacturing, eliminating the need for separate formwork anchor systems.
2Reliability
If formwork anchors are installed manually to prevent formwork collapse, then the reliability of the manufacturing process is improved, but the productivity and automation level decrease
Solution Approach 1:
The material output unit automatically pushes the load transfer elements out of the print pathway during normal operation, eliminating the need for manual intervention. This self-service mechanism maintains manufacturing reliability while preserving productivity and automation.
Solution Approach 2:
The load transfer elements are pre-positioned in the print pathway before manufacturing begins. The material output unit then automatically interacts with these pre-positioned elements during the manufacturing process, eliminating the need for real-time manual adjustments and maintaining continuous production flow.
3Manufacturing precision
If load transfer elements are placed in the print pathway to stabilize the component, then the manufacturing precision and component stability are improved, but the device complexity increases due to coordination requirements
Solution Approach 1:
The material output unit itself performs the function of coordinating with the load transfer elements by automatically pushing them out of the print pathway through normal material deposition. This eliminates the need for separate coordination systems or control mechanisms, as the material output unit's inherent motion and force are sufficient to manage the load transfer elements.

AI summary
In a method of additively manufacturing a component from a building material, a material output unit deposits the building material in layers along a defined print pathway. At least, one load transfer element extends into the print pathway. The material output unit deposits the building material onto the load transfer element present in the print pathway, and a load transfer element present in a movement pathway of the material output unit is at least temporarily pushed out of the print pathway by the material output unit while the material output unit deposits the building material along the defined print pathway.
