3D printed realism brings ancient artefacts to life


Underscoring the power of realism in 3D printed models, Stratasys and Google Arts and Culture are re-imagining some of the world’s most cherished artefacts and historical monuments through additive manufacturing. Backed by advanced colour and multi-material functionality of the Stratasys J750 3D printer, historians can now re-create these items digitally and physically – raising both awareness and accessibility of ancient history.

Google Arts and Culture is capitalising on Stratasys technology for its Open

Heritage Project – designing and creating historical pieces with multi-material and multi-colour 3D printed prototypes. With 3D printing, these remains can be more effectively preserved and shared – with files available for download around the world. The result is enhanced accessibility, in-depth understanding, and enriched appreciation of centuries old cultures.

‘The project was to explore physically making these artefacts in an effort to get people hooked and excited about seeing pieces in a museum or research context. That is when we turned to 3D printing,’ said Bryan Allen, design technologist at Google. ‘With the new wave of 3D printed materials now available, we are able to deliver better colours, higher finish, and more robust mechanical properties – getting much closer to realistic prototypes and final products right off the machines.’

The Stratasys J750 offers some of the broadest colour ranges for creation of highly realistic models. Leveraging more than a half million distinguishable colours and materials – from rigid to opaque, flexible to transparent – design teams can better align output with design objectives – all while streamlining iterations and advancing functionality of 3D printed models.

One of the major initiatives for Google Arts and Culture is restoration of rare plaster casts initially discovered by A P Maudslay during the late 1800s in Guatemala. For more than 100 years, these relics were housed across storage facilities in the British Museum. By leveraging 3D laser scanners to virtually reassemble each, designers successfully reconstructed these items in physical form with Stratasys 3D printing – later allowing representations to be easily viewed by a wider audience online.

‘The J750 empowers designers to actually achieve their ultimate goal – matching the final 3D print to what is initially seen on the screen. Combining rich colours and translucency in a single print, designers and engineers can build models with heightened levels of accuracy and realism – mirroring opaque or transparent structures, and even complex materials like rubber,’ said Rafie Grinvald, enterprise product director of Rapid Prototyping, Stratasys. ‘Our relationship with Google Arts and Culture is the perfect demonstration of 3D printing paying off – with models that look and feel like the real thing.’

Key pieces of the Google Arts and Culture Open Heritage Project are available anytime online – exploring the backstory and 3D printed representation of each historical location. Visitors can access the models at artsandculture.google.com/project/cyark

‘When we talk to arts and culture preservationists, historians, and museum curators – they are all absolutely amazed by the ability to fabricate these things with such high fidelity via 3D printing technology,’ concluded Bryan.
