3D Scanning and Additive Manufacturing Replicate 1,700-Year-Old Roman Artifact

Somerset Council’s library service in the United Kingdom has used handheld 3D scanning and additive manufacturing to produce a detailed replica of the Ilminster Ring, a 1,700-year-old Roman gold artifact dating back to 297 AD. The physical copy was created to allow museum visitors and the public to handle and closely inspect the historical object without subjecting the delicate gold original to unnecessary wear or risk of damage.

3D Scanning and Archival Printing in Community Spaces

The project utilised a high-resolution handheld 3D scanner to capture the intricate surface details and geometry of the ring. The resulting digital mesh was refined into a printable model, enabling an accurate physical reproduction. The initiative forms part of a broader ten-year digital technology programme run by Somerset Libraries, which provides public access to 3D design, scanning, and printing tools.

Beyond historical preservation, community 3D printing facilities demonstrate clear practical utility for local enterprise and education. Over the past decade, the same library setup has supported various practical applications, including:

• Prototyping local commercial parts: Producing custom components and low-volume replacement parts for local businesses, such as specialized items for electric mobility products.
• Custom community manufacturing: Printing specialized items and oversized components for local projects where commercial off-the-shelf alternatives are unavailable or prohibitively expensive.
• Educational engagement: Offering hands-on demonstrations that introduce students and the public to 3D scanning workflows, digital model preparation, and additive manufacturing techniques.

Similar heritage preservation projects across the globe highlight the growing reliance on digital archiving. Museums and historical sites frequently turn to 3D scanning to conserve fragile fossils, replicate architectural structures, and reproduce marine archaeology finds. Using accessible desktop scanning and printing hardware allows smaller regional bodies to achieve results previously limited to major research institutions.

What This Means for South African Makers

For South African makers, educators, and cultural institutions, this project highlights the practical accessibility of 3D scanning and printing. Museums, educational centres, and historical sites across South Africa hold invaluable cultural artifacts that cannot be routinely handled by students or visitors. Incorporating handheld 3D scanning and desktop printing allows local institutions to create durable, tactile models for interactive displays, school outreach programs, and research.

Small design studios and print service providers in South Africa can also draw inspiration from this hybrid workflow. Combining digital capture with desktop FDM or resin printing opens commercial opportunities in custom restoration, reverse engineering of discontinued parts, bespoke prop making, and educational kit production. The technology required to capture and reproduce intricate physical items is now well within reach of independent workshops and small print farms.

DC3D’s Take

Using 3D scanning alongside desktop 3D printing for artifact reproduction is a pragmatic demonstration of how digital workflows solve real-world problems. While high-end scanners provide exceptional accuracy, mid-range handheld scanners and structured light systems paired with high-resolution resin or fine-tuned FDM printers can yield impressive results for historical replicas and functional prototypes alike.

The real value lies in the complete pipeline: capturing physical geometry, refining the digital model, and selecting the correct printing process and post-processing finish—such as metallic paints or electroplating—to match the original object. As 3D scanning software becomes more user-friendly and affordable, combining scanning hardware with desktop manufacturing will remain one of the most practical skill sets for South African service providers, educational makerspaces, and repair centers.
