Engineering Contradiction Analysis
1Measurement precision
If conventional 3D printers provide estimated values of material usage amount and printing time, then users can plan printing operations, but the estimation procedure takes a long time and the estimated values greatly differ from actual values
Solution Approach 1:
The 3D model data is segmented into multiple areas based on material types and printing patterns. The area splitting part divides the printing object into distinct regions, and the material determining part identifies materials for each area separately. This segmentation enables parallel processing of estimation calculations for different areas, significantly reducing total estimation time while maintaining accuracy by considering specific material properties and printing parameters for each region.
Solution Approach 2:
The system performs preliminary analysis by storing 3D model data and usage amount information in advance. The database is pre-configured with material usage rates, printing speeds, and process parameters. When estimation is needed, the system retrieves pre-stored data and applies it to the segmented areas, avoiding time-consuming real-time calculations and delivering accurate estimates quickly.
2Manufacturing precision
If different materials are determined and prepared in advance for respective parts of the printing object, then printing quality is improved, but material waste increases when material depletion requires restarting the printing process
Solution Approach 1:
The system performs preliminary estimation of material usage amounts for each area and each material type before the printing process begins. By analyzing the 3D model data and calculating required materials in advance, users can prepare exactly the needed amounts of each material, preventing both shortages that would require restarts and excesses that would cause waste.
Solution Approach 2:
The system provides feedback on estimated material usage amounts and printing times to users before printing starts. This feedback loop allows users to adjust material preparations and printing plans based on accurate predictions, ensuring optimal material utilization and preventing the need to restart printing due to material depletion.
3Manufacturing precision
If the entire printing process is restarted from the beginning when a specific material is used up, then printing quality is maintained, but productivity decreases and time is lost
Solution Approach 1:
The system calculates and provides preliminary estimation of total material usage amounts for each material type before printing begins. Users can prepare sufficient quantities of all required materials in advance, eliminating the risk of material depletion during printing and avoiding the need to restart the printing process, thus maintaining both quality and productivity.
4Ease of operation
If conventional 3D printers do not provide accurate estimation, then users cannot plan resource allocation, but material waste and time loss increase
Solution Approach 1:
The system provides accurate feedback on estimated material usage amounts and printing times based on analysis of the 3D model data. This information enables users to make informed decisions about material preparation and scheduling, optimizing resource allocation and preventing both material waste and operational inefficiencies.
