Independent Coating Devices for 3D Construction Laminates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for producing three-dimensional laminates in the construction industry face limitations due to non-independent movement of coating devices and printing heads, leading to restricted suitability and longer cycle times, especially when dealing with large volumes of particulate material.
Innovation Solution
The apparatus allows for independent movement and differential speeds of at least two coating devices and one printing head, with each component having autonomous drive means and being mountable along a common longitudinal guide, enabling simultaneous and efficient application and hardening of particulate material layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If coating devices and printing head are connected together and moved together, then structural simplicity is maintained, but cycle time increases and productivity decreases
Solution Approach 1:
The apparatus divides the coating system into multiple independent coating devices (first coating device, second coating device) that can operate separately. Each coating device can be independently positioned and operated, allowing parallel processing where one coating device fills while another applies material, thereby reducing cycle time without excessive complexity
Solution Approach 2:
The coating devices are made dynamically positionable along the longitudinal guide, allowing them to move independently to optimal positions. The printing head and coating devices can be positioned at different locations along the guide, enabling dynamic optimization of the printing cycle by having coating devices ready in advance at strategic positions
2Manufacturing precision
If coating devices are filled with large amounts of particulate material, then uniform layer thickness is achieved, but filling time increases and delays printing operation
Solution Approach 1:
Coating devices are pre-filled with particulate material before the printing operation begins. The first coating device can be filled in advance while the second coating device is already positioned and ready to apply material. This preliminary preparation eliminates filling delays during the printing cycle
Solution Approach 2:
The system maintains continuous operation by having multiple coating devices in different operational states simultaneously. While one coating device is being filled, another is applying material to the printing platform. This continuous workflow ensures that the printing head never waits for coating device filling, maintaining uniform layer thickness without time loss
3Productivity
If coating devices are positioned upstream of printing head, then material application is efficient, but return movement of coating devices creates idle time
Solution Approach 1:
The system adds the longitudinal dimension along the guide to the positioning strategy. Coating devices can be positioned at different longitudinal locations upstream of the printing head, allowing them to apply material in sequence or parallel without requiring return trips to a single filling position. This multi-position arrangement eliminates idle travel time while maintaining efficient material application

AI summary
A device for producing a three-dimensional laminate for the construction industry from a plurality of layers of particulate material, which layers are arranged one on top of the other on a printing platform, are consolidated in locally predetermined regions, and are bonded to one another to form a three-dimensional laminate. The device includes a printing frame and at least two coating devices for applying the particulate material layer by layer on the printing platform. The at least two coating devices are movably mounted on the printing frame, preferably along a longitudinal guide. A printing head is provided for discharging a binder at the locally predetermined regions, and the printing head is movably mounted on the printing frame, preferably along at least one longitudinal guide. The at least two coating devices and the printing head are in each case movable in relation to one another.
