In the world of sculpture and art, 3D scanning technology has revolutionised the way masterpieces are captured and preserved. In this article, we explore how the EinScan H portable 3D scanner has enabled the Swedish company nioform to 3D scan five tall 19th century bronze sculptures located outdoors. Join us on this journey from artistic creation to digitisation and fabrication.
Context of the project
Joakim, founder of nioform, is a true maker who works with polystyrene foam, polyurethane and wood to create models and sculptures. Recently, he was commissioned to capture five 19th century bronze sculptures in 3D. These large, outdoor sculptures presented a unique challenge. Joakim needed to secure the 3D data of the sculptures without damaging the originals.
Comparison of 3D scanning technologies
Joakim has been familiar with 3D scanning technology for more than 15 years, using both structured light scanners and photogrammetry. However, for this specific project, he needed a more efficient and accurate solution.
The solution: EinScan H
The EinScan H is a portable 3D scanner that combines structured LED light with infrared light to capture 3D geometries. Its integrated camera also acquires the colours of the object, allowing for a complete representation. With an accuracy of up to 0.05 mm in scanned data and a volumetric accuracy of 0.1 mm/m, the EinScan H became the ideal tool for this project.
For the 3D scanning project of the bronze sculptures, the Swedish company nioform used the KUKA milling robot. Joakim, the founder of nioform, relied on the portable EinScan H 3D scanner to capture the 3D data of the sculptures. The EinScan H is a versatile tool that offers an accuracy of up to 0.05 mm on the scanned data and a volumetric accuracy of 0.1 mm/m. In addition, Joakim has also experimented with the new EinScan H2, which further enhances the workflow with its infrared mode.
In short, the combination of 3D scanning technology and robots such as the KUKA and the EinScan H has made it possible to digitally preserve and enlarge these valuable bronze sculptures.
Overcoming the challenges of outdoor 3D scanning
Scanning sculptures outdoors presents additional challenges, such as the variability of sunlight and environmental conditions. The EinScan H proved capable of capturing fine details and providing real-time information during the scanning process. Joakim significantly reduced scanning time and obtained reliable results.
The combination of art, technology and 3D scanning has enabled nioform to digitally preserve and enlarge these bronze sculptures. The EinScan H has proven its worth as a professional tool for sculpture and artistic heritage projects. In a world where creativity meets precision, the EinScan H is an indispensable ally.
