Automatic Leveling Apparatus for 3D Printing Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In photocuring 3D printing, manual leveling of the printing platform leads to unstable connections and potential movement during printing, affecting the precision and stability of the first layer of the printed model due to uneven inclination and distance between the printing platform and the light-transmitting screen.
Innovation Solution
A leveling apparatus with a driving assembly and transmission assembly that adjusts the inclination or height of the target component, such as the resin vat, using electrical signals to maintain a uniform gap and prevent manual operation errors, incorporating a measurement module with a displacement sensor to ensure precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual leveling of the printing platform is performed, then the inclination and distance between the printing platform and light-transmitting screen can be adjusted, but the connection becomes unstable and the platform may move during printing
Solution Approach 1:
The patent replaces the manual mechanical leveling system with an automatic leveling apparatus that uses a driving assembly (motor-driven) and transmission assembly (lead screw or rack and pinion) to adjust the printing platform's inclination and height. This substitution eliminates manual operation errors and ensures stable, precise positioning without compromising connection stability during printing.
2Ease of operation
If the printing platform is adjusted manually, then leveling can be achieved, but operation errors and movement during fixing occur
Solution Approach 1:
The leveling apparatus is designed to perform self-leveling operations through automatic control. The driving assembly receives control signals and automatically adjusts the printing platform's position and inclination without requiring manual intervention, thereby eliminating operation errors while maintaining high leveling accuracy.
Solution Approach 2:
The system incorporates sensors that detect the printing platform's position and inclination in real-time, providing feedback to the control system. This closed-loop feedback mechanism enables automatic adjustment to achieve precise leveling while preventing movement during the fixing process, as the system continuously monitors and maintains the desired position.
3Reliability
If the printing platform is manually fixed with bolts, then positioning can be achieved, but the platform is prone to movement during screwing
Solution Approach 1:
The patent replaces the manual bolting fixation system with an automatic driving assembly that uses a lead screw or rack and pinion mechanism. This mechanical substitution allows for precise, controlled adjustment of the printing platform's position and inclination without manual intervention, eliminating movement during fixation while maintaining high positioning precision through controlled mechanical transmission.

AI summary
A leveling apparatus for leveling a 3D printer includes a leveling module. The leveling module is used to push or pull back a target component in a first direction under the control of an electrical signal. The leveling module includes a driving assembly and a transmission assembly. A first end of the transmission assembly is connected to the driving assembly, and a second end of the transmission assembly is configured to be directly or indirectly connected to the target component. The driving assembly is connected to the transmission assembly to drive the transmission assembly to move, so as to push and/or pull back the target component in the first direction.
