This article focuses on 3D scanning and 3D printing glass statues, in order to reproduce an iconic fountain.
Name: Fablab Arnhem for Museum Lalique
Location: Arnhem, Netherlands
Subject: 3D scanning and 3D printing glass statues
Need: Get a high-resolution 3D scan of a glass statue in order to duplicate it by SLA 3D printing. (This can be difficult for a little statue with only 11 cm tall)
Solution: SHINING 3D OptimScan 5M Plus
Results:
●Quick data capture with only two scans
●0.005mm accuracy achieved, with 0.04mm point distance
●3D printing glass replicas with extra fine details
Recreating the Charm of Les Sources de France Fountain
The Paris International Exhibition of Modern Decorative and Industrial Arts in 1925 featured the Les Sources de France fountain. It consisted of 128 female glass statues that depict Greek mythological figures. They symbolize the origin of all life. The fountain was 14 meters in height and contained 140 water-spouting objects. The fountain would light up from the inside, which led to a spectacle at night. But after the world expo, authorities demolished the fountain and sold the statues.
After almost 100 years, Museum Lalique wanted to bring back the iconic fountain and planned to show it in a new exhibition. However, the original statues have been hard to find. The Museum Lalique has kept a tiny statue of the muse Calliope from the same era. Thus, they asked Fablab Arnhem to help them reproduce several miniatures and create a scale model of the fountain.
Fablab Arnhem is located at the HAN University of Applied Sciences in the Netherlands. As an innovative workspace for digital technologies, Fablab Arnhem provides workshops and equipment for people from various industries to learn about technologies such as 3D scanning and modeling.
3D Scanning and 3D Printing Glass Statues
Making a Mould and Pouring
In view of the high value of the statue and the difficulty of scanning the reflective surface of the glass, Fablab Arnhem decided to create a replica for scanning first. They created a silicone mold of the statue and then cast it using polyurethane. The polyurethane has a frosted white finish which worked perfectly for 3d scanning. Now, Fablab Arnhem got a highly accurate replica.
3D Scanning Glass Statue’s Replica
Fablab Arnhem decided to apply the OptimScan 5M Plus metrology 3D scanner.
The height of the Muse Calliope statue was only 11cm, and Fablab Arnhem needed to enlarge its replica to 38cm. When enlarged, even small imperfections would be easily seen. Thus, they had to make sure that all the details of the scan were correct. For this reason, the advantages of the OptimScan 5M Plus are clear:
●Using the OptimScan 5M Plus – 100mm lens, achieve highest resolution with point distance of 0.04mm and reach accuracy up to 0.005mm.
●Desktop based 3D scanner, more capable for capturing fine details.
●Only two scans (front and back) needed for the complete data.
●The latest software is easier to use.
Digital Post-processing
After taking the scan, Fablab Arnhem used Blender to refine the model. The high-fidelity scan with high resolution (small point distance) allows them to clearly see all fine-detailed features. So, they can make the model stay as close to the original as possible. Like with physical sculpting, they filled the holes and smoothed it out. Finally, they smoothed out the noise that would be visible after scaling up the original scan to 38cm.
3D Printing Glass Statues
Through the use of SLA 3D printing techniques, Fablab Arnhem was able to print the Muse Calliope in three new sizes. The SLA printing technique is known for its detailed prints and the smoothness between the printing layers that almost makes the printing layers invisible to human eyes. They used a crystal-like resin to simulate a glass look and polished them to increase the transparency.
Final Steps
In like manner, Fablab Arnhem will use these three new prints to make new large silicone moulds. They will use these moulds to cast 12 statues of various sizes in transparent, UV-resistant polyurethane. These cast polyurethane pieces are the final statues that will be used for the fountain.
Conclusion
In conclusion, the article highlights how 3D scanning and printing can prove to be a useful tool for the re-creation of art, as demonstrated by the successful reproduction of glass statues. By 3D scanning, modeling, and 3D printing glass statues using OptimScan 5M Plus, Blender, and SLA technology, Fablab Arnhem will allow visitors to feel the fountain again. Also, the museum will display three printed and polished statues to demonstrate the process of utilizing new technologies to restore art history in an accessible way.
