1Productivity
If conventional support removal methods are used with multiple removal methods applied simultaneously, then support material removal rate is improved, but part damage increases due to suboptimal application of methods
Solution Approach 1:
The system dynamically adjusts the parameters and intensity of multiple removal methods (thermal, chemical, mechanical agitation) in real-time based on feedback from sensors monitoring the part and support material state. This dynamic control allows the system to optimize the combination of methods for maximum removal rate while preventing part damage by adapting to changing conditions during the removal process.
Solution Approach 2:
The invention changes multiple parameters simultaneously including temperature, chemical concentration, agitation intensity, and their combinations. By systematically varying these parameters and their interactions, the system achieves optimal support material removal while minimizing harmful effects on the part. The control system monitors and adjusts these parameters to maintain them within optimal ranges.
2Device complexity
If conventional support removal methods are used with fixed control systems, then system complexity is reduced, but removal efficiency decreases due to inability to optimize for specific part characteristics
Solution Approach 1:
The system incorporates sensors that continuously monitor the part, support material, and process conditions. This feedback is fed to a control system that automatically adjusts removal method parameters to optimize efficiency for each specific part. The feedback loop enables the system to adapt to diverse part characteristics without requiring complex manual programming for each part type.
Solution Approach 2:
The control system automatically determines and adjusts the optimal removal parameters based on sensor data and part characteristics, reducing the need for manual intervention and complex pre-programming. The system serves itself by making real-time decisions about parameter optimization, thereby achieving high removal efficiency without proportionally increasing operational complexity.
3Productivity
If aggressive removal methods are used to increase removal rate, then support material removal speed is improved, but surface finish quality deteriorates
Solution Approach 1:
The system employs periodic cycles of aggressive removal followed by gentler removal phases. During aggressive phases, higher intensity removal methods are applied to rapidly remove bulk support material. During gentler phases, the intensity is reduced to refine the surface finish. This periodic alternation allows the system to achieve both high removal speed and good surface quality.
Solution Approach 2:
The system applies aggressive removal methods partially - using them only when and where needed to remove bulk support material, then transitioning to gentler methods for surface refinement. This partial application of aggressive action achieves the benefits of fast removal without the continuous harmful effects on surface finish.

AI summary
A process for support material removal for 3D printed parts wherein the part is placed in a media filled tank and support removal is optimized in a multi-parameter system through an artificial intelligence process which may include, but is not limited to, the use of historical data, parametric testing data, normal support removal data, and outputs from other support removal AI models to generate optimally efficient use of each parameter in terms of pulse repetition interval (PRI) and cycle time as defined by pulse width (PW). The input parameters may include heat, circulation, ultrasound and chemical reaction, which are used in sequence and/or in parallel, to optimize efficiency of support removal. Sequentially and/or in parallel, heat, pump circulation and ultrasound may vary in application or intensity. Selection of means of agitation depends on monitored feedback from the support removal tank and application of a statistically dynamic rule based system (SDRBS).
