Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional printer systems lack the ability to efficiently modulate their operational parameters to achieve specific physical properties in outputs, such as color, strength, and dimensional accuracy, leading to inconsistencies and inefficiencies in the printing process.
Innovation Solution
A control system for three-dimensional printers that allows users to select from multiple operational modes, each defining a range of tolerances for physical properties, enabling the modulation of energy, material deposition, and agent application parameters to achieve desired output characteristics, including the use of fresh or recycled build materials and varying the energy and agent deposition rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If operational parameters are fixed without modulation capability, then device complexity is reduced, but manufacturing precision and adaptability deteriorate due to inability to achieve specific physical properties
Solution Approach 1:
The patent implements dynamic modulation of operational parameters (energy component parameters, material depositing component parameters, agent depositing component parameters) based on selected modes. The control system continuously adjusts these parameters rather than using fixed values, enabling the system to adapt to different mode requirements and achieve precise control over output physical properties while managing complexity through systematic control architecture.
Solution Approach 2:
The patent changes operational parameters (energy delivery amount, material deposition rate, agent application rate) based on selected modes. Each mode defines specific parameter ranges that map to desired physical properties of the output, allowing the system to achieve manufacturing precision by systematically varying parameters according to mode-specific requirements.
2Adaptability or versatility
If multiple modes with different tolerance ranges are implemented, then adaptability improves, but device complexity increases due to additional control logic
Solution Approach 1:
The control system is designed with multi-functionality to handle multiple modes of operation. A single control system architecture supports different modes (each with different tolerance ranges and parameter mappings) without requiring separate control systems for each mode. This universal approach enables adaptability while managing complexity through a unified control framework that can switch between different operational configurations.
3Manufacturing precision
If tolerance ranges are restricted for high precision, then manufacturing precision improves, but productivity decreases due to slower production speed
Solution Approach 1:
The system dynamically adjusts operational parameters based on the selected mode's tolerance requirements. When a mode with restricted tolerance ranges is selected, the control system modulates parameters to achieve higher precision. When productivity is prioritized, the system can select modes with relaxed tolerances. This dynamic adaptation allows the system to optimize the trade-off between manufacturing precision and productivity based on operational requirements.

AI summary
A control system for a three-dimensional printer includes an energy component interface, an agent depositing component interface, and control logic. The control logic controls the operation of an energy component through the energy component interface and an agent depositing component through the agent depositing component, in forming an output object that is specified in a print job. Additionally, in some examples, the control logic can implement a plurality of modes. Each mode, when selected modulate one or more operational parameters of a least one of the energy component or agent depositing component.
