Solution Overview

Problem

Existing 3D printing methods require significant time and resources to generate a single model of an entire component output, which increases with the number of copies to be fabricated, making the process inefficient for producing multiple copies of a component.

Innovation Solution

A method where a printing device receives a three-dimensional component model, segments it into a stack of slices, and outputs respective printing layers for each slice according to an output structure definition, allowing for the generation and output of multiple copies without creating a single model of the entire component.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a single model of the entire component output is generated to fabricate multiple copies via 3D printing, then the component can be reproduced accurately, but the time and computational resources required increase significantly with the number of copies

Engineering Contradiction:
Improvecomponent reproduction accuracyVSAvoidmodel generation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent segments the component model into multiple slices along the build direction. Each slice is processed independently to generate printing layers, avoiding the need to generate a single comprehensive model for all copies. This segmentation reduces computational complexity and model generation time while maintaining printing accuracy for each component copy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of generating one large model containing all copies, the patent creates individual slice representations that can be replicated and arranged according to the output structure definition. Each slice instance is a simplified copy that can be processed independently, reducing the overall computational burden while preserving the ability to produce multiple accurate copies.

Inventive Principle:
Principle #26Copying

2Manufacturing precision

If a single model of the entire component output is generated to fabricate multiple copies via 3D printing, then the component can be reproduced accurately, but the computational resources required increase significantly with the number of copies

Engineering Contradiction:
Improvecomponent reproduction accuracyVSAvoidcomputational resource requirements
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent divides the component model into discrete slices, allowing the printing system to process and generate layers for each slice independently. This segmentation reduces the computational complexity of model generation, as the system only needs to handle individual slice instances rather than a comprehensive model of all copies, while maintaining manufacturing precision through accurate slice-to-layer mapping.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes slice instances as simplified copies that can be replicated and arranged according to the output structure definition. Each slice instance requires minimal computational resources compared to generating a complete model of all copies, thereby reducing overall device complexity and resource requirements while preserving component reproduction accuracy.

Inventive Principle:
Principle #26Copying

3Manufacturing precision

If successive layers are added to reproduce a component via 3D printing based on a complete model, then accurate component fabrication is achieved, but the printing process becomes inefficient for producing multiple copies

Engineering Contradiction:
Improvecomponent fabrication accuracyVSAvoidprinting efficiency for multiple copies
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent segments the printing process by processing individual slices independently. Each slice is converted to printing layers and arranged according to the output structure definition, allowing parallel or sequential processing of multiple slice instances. This segmentation enables more efficient production of multiple copies compared to processing a single comprehensive model, while maintaining component fabrication accuracy through precise layer generation for each slice.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates multiple slice instances that can be arranged and processed efficiently. Each slice instance represents a copy of the component at a specific build layer, allowing the system to generate printing instructions for multiple copies simultaneously or in parallel, thereby improving productivity while maintaining manufacturing precision through accurate slice-to-component mapping.

Inventive Principle:
Principle #26Copying
