Fabricating Wood-Like Textures on Multicurved 3D Printed Architectural Elements

Area of Science:

• Materials Science
• Additive Manufacturing
• Architectural Design

Background:

• Fused filament fabrication (FFF) is common for small, layered 3D prints.
• Automating large-scale, complex architectural elements with fluid surfaces remains a challenge.
• Existing methods often produce horizontally layered, striated appearances unsuitable for natural timber aesthetics.

Purpose of the Study:

• To investigate 3D printing techniques for multicurved architectural elements.
• To develop wood-plastic composite panels with a natural timber appeal.
• To compare the capabilities of six-axis robotic and gantry-style 3D printers for complex shapes.

Main Methods:

• Exploration of three-dimensional (3D) printing using wood-plastic composites.
• Comparison of a six-axis robotic arm printer with a large-scale gantry-style printer.
• Analysis of printing processes for smooth, curved layers in complex geometries.

Main Results:

• Both six-axis robotic and gantry-style 3D printing technologies can create multicurved elements.
• The printed elements exhibit a desirable timber-like aesthetic.
• The research demonstrates feasibility for large-scale architectural components.

Conclusions:

• Advanced 3D printing techniques can overcome limitations in producing complex architectural forms.
• Wood-plastic composites offer a viable material for aesthetically pleasing, large-scale 3D printed elements.
• The study paves the way for automated construction of fluid, natural-looking architectural components.
