Creating 3D models of cultural artefacts can help to foster learning and provide new ways of engaging with heritage. The process can also offer access to resources previously denied to audiences and can help preserve fragile items.
Essentially there are two approaches to creating three dimensional assets:
- 3D scanning is a non-contact, non-destructive technology that digitally captures the shape of physical objects and visualises them in a digital 3D space. There are many methods of undertaking 3D scanning including but not limited to photogrammetry, which is arguably the most accessible, laser-based scanning and structured light scanning.
- 3D printing, or additive manufacturing, is a process of making three dimensional solid objects from a digital file. In an additive process, an object is created by layering material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.
Using 3D scanning and printing in heritage organisations presents you with both challenges and implications. It can allow you to:
- Rapidly replicate objects
- Disseminate and share artefacts digitally and physically
- Support repatriation
- Enhance audience and learning programmes.
Yet at the same time, it challenges current Intellectual Property laws, requires additional digital skills and can have a significant cost.
In this resource our expert, Dr Amelia Knowlson, University of Leeds, will explore the Intellectual Property implications of 3D scanning and what you need to consider when digitalising your collection.
According to the World Intellectual Property Organisation (WIPO), copyright laws will protect the originality of a work and the creator’s right to reproduce it. This means that if copies of an original object are 3D printed without authorisation, the creator can obtain relief under copyright law.
So, if a heritage organisation has a work in their collection that is in copyright, they will need to secure permission from the owner of the work’s copyright to reproduce it.
Copyright and 3D scanning
3D scanning is more of a grey area. Many individuals believe the creation of a 3D scan would have its own copyright protection, as the author of a 3D scan must make a personal, creative, and intellectual effort to create a functionable object for either the digital or physical realm. However, at the time of creating this resource, there is no legal test to determine whether copyright would be assigned to the creator of a 3D scan if the original artefact is still in copyright.
It is also important to consider the moral implications of 3D scanning artefacts of contested origins. Heritage organisations which house artefacts stolen from their countries of origin, or where the method of acquisition is unknown, should question whether it is morally right to 3D scan these artefacts.
Copyright or Creative Commons?
Once a 3D scan has been created, the next thing to consider is what level of copyright or Creative Commons license needs to be applied to the 3D scan. Advice on applying Creative Commons can be found at Creative Commons. Examples of how Creative Commons can be applied to historical museum objects can be seen on SketchFab – Heritage. Sketchfab allows global audiences to access and make use of 3D models representing cultural heritage from around the world through virtual visits, examining 3D scans of objects and adding annotations to the models. Museums such as the British Museum apply CC Attribution-Non-Commercial-Share-Alike (CC BY-NC-SA) with a downloadable model feature on the site. This license allows users to access and use the model provided they attribute the model to the British Museum, use it for non-commercial purposes and, if any different versions are made, distribute these under the same license.
Now that you have examined some ideas around 3D modelling and copyright, you might find it useful to explore an example which can help you think through how to approach this in your own organisation.
If you are considering using 3D scanning and printing to digitalise your collection, you can use these questions to help identify potentially appropriate artefacts:
- Is the institution the current copyright holder?
- What reasons do you have for using 3D scanning (think about museum research/education/outreach/repatriation)?
- Is the object’s acquisition contested?
- Is the object culturally insensitive?
- Is it appropriate to digitalise this artefact (think about policies of display around human remains)?
- How will the digital object be displayed and what Creative Commons or copyright protections will be applied?
The key points to take away are:
- 3D scanning and printing can be a costly and time-consuming venture, so it is important any digital project involving this technology is embedded within the museum strategy.
- Take time to explore whether your institution holds copyright for the artefact you wish to digitalise and always make sure you ask permission from the copyright holder before 3D scanning.
- 3D scanning creates new opportunities to share collections, so when visualising 3D scans think carefully about accessibility. Allowing audiences to download, share and even 3D print artefacts encourages new forms of audience engagement.
