Solution Overview

Problem

When adding text to a three-dimensional model with severely curved surfaces, the text often separates from the model during the three-dimensional printing process due to compatibility issues.

Innovation Solution

A method that determines the combinability of three-dimensional text data with a three-dimensional model by applying an offset and checking for intersections, allowing for optimal positioning and integration of text on the model, ensuring it remains attached during printing.

1Ease of operation

If text is added on a three-dimensional model with severely curved surfaces, then the text can be displayed on the model, but the text separates from the model during the three-dimensional printing process

Engineering Contradiction:

Improvetext display on modelVSAvoidtext attachment during printing

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary intersection detection between the text data and three-dimensional model data before printing. By checking whether the text intersects with the model surface in advance, the system identifies suitable positioning areas where the text can be properly attached to the model, preventing separation during the printing process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides visual feedback by displaying intersection detection results to the user. When text is positioned in an unsuitable area, the system shows that no intersection occurs, guiding the user to adjust the text position until proper intersection is achieved, ensuring reliable text attachment during printing.

Inventive Principle:

Principle #23Feedback

2Productivity

If text positioning is performed without intersection detection, then the process is simple and fast, but the text may not be properly integrated with the model

Engineering Contradiction:

Improvetext positioning speedVSAvoidtext-model integration accuracy

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The system replaces manual trial-and-error text positioning with automated intersection detection using computer processing. The processor automatically determines whether text data intersects with the three-dimensional model data, providing precise positioning guidance without requiring manual adjustment, thus maintaining high productivity while achieving accurate text-model integration.

Inventive Principle:

AI summary

A method of adding text on a three-dimensional model representing an object includes obtaining three-dimensional text data corresponding to at least one character, displaying the three-dimensional text data and the three-dimensional model on a screen, determining whether the three-dimensional text data and the three-dimensional model are combinable with each other based on whether the three-dimensional text data with a certain offset applied thereto and the three-dimensional model intersect each other, and displaying a result of the determining on the screen.
