3D Printer Calibration Offset Storage for Cycle Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing three-dimensional shaping devices require frequent calibration when a shaping plate is attached, leading to increased cycle times in shaping multiple objects due to the need to re-calibrate each time the plate is used, which is inefficient.
Innovation Solution
An information processing system that includes acquisition units for identifying shaping plates and devices, and a control unit to store and associate this information, determining whether to perform calibration based on the use history of the shaping plate and device, thereby optimizing the calibration process and reducing cycle times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration is performed every time a shaping plate is attached to improve measurement precision, then the shaping accuracy is maintained, but the cycle time increases due to frequent recalibration
Solution Approach 1:
The system performs calibration in advance and stores the calibration results (offset values) in a storage device. When a shaping plate is attached, the system retrieves pre-stored calibration data instead of performing calibration again, thus maintaining measurement precision while avoiding time-consuming recalibration operations.
Solution Approach 2:
The system creates a copy of the calibration results (offset values) and stores them in a database associated with specific shaping plate identification information. This copied calibration data can be quickly retrieved and applied without performing the actual calibration process again, resolving the contradiction between maintaining precision and reducing time loss.
2Productivity
If calibration is skipped to reduce cycle time, then the productivity increases, but the measurement precision deteriorates leading to shaping errors
Solution Approach 1:
The system performs calibration in advance before production runs and stores the results. During actual shaping operations, the pre-calibrated offset values are retrieved and applied, allowing high-speed production without compromising measurement precision since the calibration data was obtained under controlled conditions beforehand.
Solution Approach 2:
The calibration results are copied and stored in association with shaping plate identification information. This allows the system to quickly retrieve and apply accurate measurement data during production without performing time-consuming calibration operations, thus maintaining both productivity and measurement precision.
3Measurement precision
If the system stores and manages calibration data for multiple shaping plates to maintain precision, then the measurement accuracy is preserved, but the device complexity increases
Solution Approach 1:
The system creates simplified copies of calibration results (offset values) and stores them in a database with basic identification information. This copying approach maintains measurement precision by preserving calibration data while using a relatively simple database structure that does not require complex data management systems.
Solution Approach 2:
The system extracts only the essential calibration parameters (offset values for nozzle height and stage height) from the complete calibration process and stores only these critical data points. This extraction approach maintains measurement precision by preserving the key calibration information while minimizing device complexity by storing only necessary data without unnecessary complexity.
