3D Printing Posture Optimization for Reduced Print Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D printing technologies require extensive time due to the need for the print head to reciprocate back and forth during layer-by-layer printing, leading to prolonged printing times, especially for larger objects and multiple printing jobs.
Innovation Solution
The method involves obtaining height groups of an object in various postures relative to a support platform, identifying the minimum and orthogonal heights, and orienting the object to align printing directions with the slowest and fastest speeds, thereby reducing printing times by optimizing the printing posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the print head reciprocates back and forth during layer-by-layer printing, then the object can be printed with high precision, but the printing time becomes excessively long
Solution Approach 1:
The patent applies dynamics by making the print head stationary and the support platform movable. The support platform moves in the printing direction to transport the printed object, eliminating the need for the print head to reciprocate. This dynamic reconfiguration of moving parts resolves the contradiction by maintaining precision through controlled platform movement while dramatically reducing time loss from reciprocation.
Solution Approach 2:
The patent inverts the conventional 3D printing approach by reversing which component moves: instead of the print head moving back and forth, the support platform moves in the printing direction. This inversion eliminates the harmful reciprocation motion while preserving the layer-by-layer printing precision, directly resolving the time-loss problem.
2Device complexity
If the object is printed in fixed posture, then the printing process is simple, but the overall printing speed is reduced due to inefficient printing directions
Solution Approach 1:
The patent applies preliminary action by pre-calculating and determining the optimal printing posture and direction before the actual printing process begins. The control unit analyzes the object's geometry and identifies the best orientation that maximizes printing speed, then configures the printing system accordingly. This preliminary optimization enables faster printing without adding complexity during the printing execution phase.
Solution Approach 2:
The patent changes the orientation parameters of the object relative to the printing direction to optimize printing speed. By adjusting the posture parameters (rotation angles, orientation) of the object on the support platform, the system aligns the printing direction with the object's geometry to minimize reciprocation and maximize efficient printing, thereby improving productivity without complicating the printing process.
