Displacement Mapping as a Highly Flexible Surface Texturing Tool for Additively Photopolymerized Components

Area of Science:

• Computer Graphics
• Additive Manufacturing
• Materials Science

Background:

• Displacement mapping offers flexible, fast, and economical surface texturing for 3D printing.
• Conventional texturing methods lack the adaptability of digital approaches.
• Texture accuracy in 3D printed parts is highly dependent on parameter selection.

Purpose of the Study:

• To demonstrate producing surface-textured parts using polygonal modeling software and photopolymerizable resin.
• To develop a universal methodology for predicting dimensional accuracy in resin 3D printing.
• To optimize parameters for achieving desired texture fidelity.

Main Methods:

• Utilizing polygonal (mesh) modeling software for texture design.
• Employing photopolymerizable resin for 3D printing.
• Characterizing printed components using scanning confocal microscopy.

Main Results:

• Reduced mesh size (10% of smallest feature) and significant overexposure (×4.5) were necessary for desired accuracy.
• Successful manufacturing of functional stamps with regular (honeycomb) and random textures.
• Established a methodology to predict dimensional accuracy for resin 3D printing.

Conclusions:

• Optimized displacement mapping and resin 3D printing parameters enable accurate production of textured components.
• The developed methodology aids in cost-effective and rapid manufacturing of innovative patterns.
• Findings are applicable to diverse fields including hobby, industrial, and biomedical sectors.
