Solution Overview

Problem

Conventional shaping devices, such as 3D printers, require significant time for shaping objects due to the need for support layers, which prolong the overall shaping process as the removal of these layers can take several hours, and the time varies with different layouts and shapes, making it inefficient to minimize shaping time without considering support layer removal time.

Innovation Solution

A shaping system and method that includes a controller capable of predicting support layer removal time based on surface area, thickness, dissolution rate, and past data, allowing for optimized layout selection to minimize total shaping and removal time, using AI technology for enhanced accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a layout is selected to minimize shaping time, then shaping speed is improved, but support layer removal time increases

Engineering Contradiction:
Improveshaping speedVSAvoidsupport layer removal time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The system performs preliminary action by predicting the support layer removal time before the actual shaping process begins. The prediction unit calculates the expected removal time based on the support layer's surface area, thickness, and material properties, allowing users to evaluate different layout options and select those that balance shaping speed with acceptable removal time, thus avoiding unexpectedly long post-processing delays

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by providing removal time predictions to users during the layout selection phase. This feedback mechanism enables informed decision-making, where users can adjust their layout choices based on the predicted removal time information, ultimately optimizing the total process time by balancing shaping and removal phases

Inventive Principle:
Principle #23Feedback

2Loss of time

If support layer surface area is reduced to shorten removal time, then support effectiveness may be compromised

Engineering Contradiction:
Improvesupport layer removal timeVSAvoidsupport effectiveness
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system applies parameter changes by allowing users to adjust the threshold value for determining whether to form a support layer. By modifying this parameter, users can balance between support effectiveness and removal time based on specific application requirements. The prediction unit calculates removal time based on the actual support layer surface area, enabling data-driven optimization of this critical parameter

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The prediction unit performs preliminary calculation of removal time based on the planned support layer configuration before the shaping process begins. This allows users to evaluate whether a proposed support layer design will result in acceptable removal time while maintaining adequate support effectiveness, and make adjustments to the design parameters accordingly

Inventive Principle:
Principle #10Preliminary action

AI summary

A shaping system for shaping a stereoscopic shaped object, the shaping system including a shaping device serving as a shaping portion and a control PC serving as a shaping controller. At a time of shaping a shaped object, the shaping device further forms a support layer that supports at least a part of the shaped object being shaped, and the control PC predicts a support layer removal time which is a time required for removing the support layer after formation of the shaped object and the support layer in the shaping device is completed.
