Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies struggle to efficiently produce non-symmetrical paired products, such as customized footwear or protective gear, due to the need for separate manufacturing lines or systems, leading to inefficiencies and increased production time, especially in extrusion deposition techniques.
Innovation Solution
A multi-head additive manufacturing machine with independently controllable deposition heads, synchronized to produce non-replica, non-mirrored segments simultaneously, using a three-dimensional reference frame and electronic control unit to coordinate movements and material deposition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single flexible manufacturing line is used to produce non-symmetrical paired products, then device complexity is reduced, but productivity decreases because only a single product can be manufactured at a time
Solution Approach 1:
The patent combines two deposition heads into a single manufacturing line, allowing simultaneous production of paired non-symmetrical products. The control unit coordinates both heads to deposit material according to different toolpaths while sharing common infrastructure (frame, guides, workspace), thus merging the functionality of two separate machines into one system.
Solution Approach 2:
The single manufacturing line is designed to handle multiple functions: it can produce symmetrical products (mirrored or replica), non-symmetrical paired products, and even single complex objects. The deposition heads can be independently controlled to adapt to different product requirements, making the system universal rather than dedicated to a single function.
2Manufacturing precision
If dedicated manufacturing lines are used for each non-symmetrical paired product, then manufacturing precision and adaptability improve, but device complexity increases because the total number of machines is doubled
Solution Approach 1:
The patent merges the functionality of two dedicated manufacturing lines into one system by equipping a single machine with two independently controllable deposition heads. Each head can follow its own toolpath with different parameters, maintaining the precision and adaptability of dedicated lines while eliminating the need for separate machines.
Solution Approach 2:
The system dynamically adapts to different product requirements through software control rather than physical reconfiguration. The control unit can programmatically adjust deposition parameters, toolpaths, and head coordination for each product type, enabling the same hardware to precisely manufacture different customized products without requiring dedicated lines for each.
3Adaptability or versatility
If extrusion deposition technique is used to print supporting features, then manufacturing flexibility improves, but productivity decreases because production time sensitively increases
Solution Approach 1:
The patent combines the deposition of supporting structures and final product material into a single coordinated operation performed by two heads. While one head deposits the final product, the other simultaneously deposits supporting structures, merging two sequential operations into one parallel process, thus maintaining flexibility while reducing production time.
Solution Approach 2:
The system performs preliminary deposition of supporting structures before the final product material in certain sequences, or simultaneously in others. The control unit plans the deposition sequence to prepare supporting features in advance or in parallel with the main product, reducing waiting time and optimizing the overall production process while maintaining the flexibility needed for complex geometries.

AI summary
A multi-head 3D printing machine has a first and second common guides for a plurality of deposition heads and provides a relative displacement between the deposition heads along a third guide, the first, second and third guides identifying a reference frame. The 3D printing machine further comprises a control unit programmed to process a sequence of discretized position information within the reference frame and deposition information so as to deposit non-replica, non-mirrored segments while the deposition heads simultaneously operate.
