Solution Overview
Problem
Existing three-dimensional shaping apparatuses face issues with part deterioration during the shaping process, leading to potential disruptions and quality deterioration when parts reach the end of their service life mid-shaping, as existing solutions do not effectively predict or manage the service life of critical components like heaters and motors.
Innovation Solution
A three-dimensional shaping apparatus equipped with a state observation section to monitor the condition of drive motors and heaters, a prediction section to estimate service life arrival times, and a control unit that notifies users and adjusts operations to ensure timely replacement, thereby preventing mid-shaping disruptions and maintaining shaping quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parts are replaced by users when deterioration occurs, then the part is maintained, but replacement may occur mid-shaping causing quality deterioration
Solution Approach 1:
The system performs preliminary detection of part deterioration and issues warnings before the part actually fails during shaping. The detection unit monitors part state continuously, and the control unit predicts remaining service life, allowing users to replace parts during idle periods rather than during active shaping operations, thus preventing quality deterioration from mid-shaping replacement
Solution Approach 2:
The system provides a buffer period between part deterioration detection and actual failure by predicting remaining service life. This cushioning time allows users to schedule part replacement during idle periods rather than being forced to replace parts mid-shaping, thereby maintaining shaping quality while ensuring part reliability
2Reliability
If part replacement is performed mid-shaping, then the deteriorated part is replaced, but shaping must be suspended and resumed causing quality issues
Solution Approach 1:
The system detects part deterioration and predicts service life arrival in advance, allowing users to schedule part replacement during idle periods before shaping operations begin or between jobs. This eliminates the need to suspend and resume shaping operations, thereby reducing time loss while maintaining part reliability
3Reliability
If no service life prediction is implemented, then the system is simple, but parts may fail unexpectedly during shaping
Solution Approach 1:
The system replaces complex mechanical monitoring and prediction mechanisms with a simplified electronic detection unit and control unit that analyze part state data. This substitution achieves reliable service life prediction and continuous shaping process monitoring with minimal added complexity, using software-based analysis rather than complex mechanical sensing systems
Solution Approach 2:
The detection unit and control unit automatically monitor part conditions and predict service life without requiring external intervention or complex external systems. The system serves itself by autonomously detecting deterioration and providing warnings, achieving high reliability with minimal added complexity

Function Achieved in This Case
The solution effectively predicts when critical components will reach the end of their service life, allowing for proactive replacement, reducing the likelihood of shaping disruptions and maintaining the quality of the shaping process by ensuring that components are replaced before they fail, thus enhancing operational reliability and consistency.

AI summary
A three-dimensional shaping apparatus includes a plasticizing section that includes a drive motor, a heater, and a screw rotated by the drive motor and that plasticizes a material to form a shaping material, a moving mechanism section that changes a relative position of an ejection section that ejects the shaping material toward a stage to the stage, a state observation section that observes a state of the drive motor or the heater, a prediction section that predicts a service life arrival time of the drive motor or the heater from an observation result of the state observation section, a notification section, and a control unit that controls the plasticizing section and the moving mechanism section to shape a three-dimensional shaped article based on shaping data. The control unit determines whether or not the service life arrival time is within a shaping time estimated based on the shaping data, and makes a notification of service life information representing a result of service life determination by controlling the notification section before shaping the three-dimensional shaped article when the service life arrival time is within the shaping time.
