3D Printing Directly onto Fabric Apparel

Solution Overview

Problem

Existing 3D printing technologies require a flat substrate and a release layer to prevent adhesion, limiting the ability to print directly onto curved or textured surfaces such as fabric materials.

Innovation Solution

The method involves using a 3D printing system that can print directly onto fabric materials without the need for a release layer or a flat substrate, allowing for the creation of complex structures on uneven surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a release layer is used to prevent adhesion during 3D printing, then the printing process can be performed, but the fabric material cannot be directly printed onto and additional assembly steps are required

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent removes the release layer from the printing system, allowing material to be deposited directly onto the fabric material without requiring a separate release layer that would need to be removed in additional assembly steps

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the substrate and fabric material into a single integrated structure by printing directly onto the fabric, eliminating the need for separate release layers and reducing assembly steps

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If a flat substrate is required for 3D printing, then printing can be performed, but curved or textured surfaces such as fabric cannot be printed onto

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent employs a dynamic printing system that can adjust to the contours and texture of the fabric material, allowing the printhead to follow the surface topology rather than requiring a static flat substrate

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the printing parameters and system configuration to accommodate curved and textured surfaces, enabling the printing process to adapt to fabric topography rather than requiring flat substrates

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If additional assembly steps are used to attach printed material to fabric, then the printing can be performed, but the process becomes more complex and time-consuming

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent performs the attachment action during the printing process itself by depositing material directly onto the fabric, so the bonding occurs preliminarily rather than requiring subsequent assembly steps

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The printing system performs the attachment function itself through direct deposition onto the fabric material, eliminating the need for separate assembly operations and making the process self-sufficient

Inventive Principle:
Principle #25Self-service
