Rotating Platform Vibration for Additive Manufacturing Powder Removal

The patent replaces manual mechanical removal tools with a vibration-based mechanical system. The shaking table generates oscillatory motion that agitates trapped powder particles, causing them to loosen and move toward evacuation openings. This substitution of manual tool-based removal with vibration-induced particle movement resolves the contradiction by enabling efficient powder evacuation from complex internal geometries without requiring direct mechanical access with small tools.

The core invention employs mechanical vibration through a shaking table that oscillates at predefined frequencies. This vibration agitates the powder particles trapped in internal cavities and cooling channels, causing them to become dislodged and migrate toward evacuation openings. The vibration mechanism directly addresses both aspects of the contradiction: it enables access to narrow passages through particle agitation rather than physical tool insertion, while simultaneously improving removal efficiency through continuous oscillatory motion that prevents powder re-deposition.

The patent implements a self-service mechanism where the component itself participates in the powder removal process. By placing the component on the shaking table, the vibration-induced agitation causes powder to move and evacuate automatically without requiring operator manipulation. This self-service approach resolves the contradiction by enabling complete powder removal through automated vibration and gravity-assisted evacuation, eliminating operator limitations while maintaining process control through programmable vibration parameters.

The patent replaces manual mechanical manipulation with an automated vibration-based system. The shaking table generates controlled oscillatory motion that substitutes for operator hand movements, while the combination of vibration and gravity creates automatic powder evacuation. This mechanical substitution resolves the contradiction by providing reliable, complete powder removal through automated means that overcome human physical limitations while maintaining precise control over the removal process.

The patent employs dynamic control of the shaking table, allowing adjustment of vibration amplitude, frequency, and duration based on component characteristics and powder removal requirements. This dynamic approach resolves the contradiction by enabling optimization of vibration parameters: sufficient amplitude and frequency are applied to evacuate powder effectively, while the controlled and time-limited nature of the vibration maintains component stability. The system adapts vibration intensity to the specific removal needs without causing excessive or prolonged component movement.

The patent utilizes parameter changes in the vibration characteristics (amplitude, frequency, duration) to control the powder removal process. By adjusting these parameters, the system achieves effective powder evacuation while maintaining component stability. The ability to modify vibration parameters allows optimization for different component types, weights, and internal geometries, resolving the contradiction between evacuation efficiency and stability through controlled parameter variation rather than fixed high-amplitude operation.
