To explore the role 3D printing could have in the Library Design scenarios were used to simulate the use of Augmented Reality in connection with 3D printing to create augment content from the book Big Sloppy Dinosaur Socks, by Jan Farr and Pamela Allen. This called on iterative design experimentation using a wide range of CAD tools and 3D printing processes. To do this 3D CAD software was used in conjunction with visual programing based generative software to create a parametric 3D model of the dinosaur illustrated in Big Sloppy Dinosaur Socks.
This scenario creates a clear connection between the Library collections and how interactions with content can be expanded into both digital and physical interactions. A functionally simple AR app is used to mediate between the content and the 3D printing. The app connects to the Library’s current implementation of 3D printing, using the UP! printers. This scenario speculates about how these technologies could be implemented at the most straightforward entry level. The print has been downloaded without any additional manipulation and the personalisation that occurs within this scenario is the hand painting of the 3D print. This gives the child the opportunity to impart their own creative vision to the appearance of the dinosaur. The personalization begins to show how the narrative can be developed through simple hand painting and it follows an interesting trajectory from the physical into digital and back to physical. This scenario speculates that following a class trip to the Library no two hand painted dinosaurs would look the same.
This scenario speculates on another level of AR with an animation to further bring the dinosaur to life before it is printed. The animation allows some customisation of the printed model by frame freezing the pose of the print. An additional narrative has been created by adding a variety of shoes. This extension invites co-creation in the form of unexpected contributions that can be supplemented or modified by anyone with access to 3D CAD software. Along with this physical feedback of receiving the shoes, the shoes could also be digitally applied to the AR model and animation, reconnecting the 3D printing back to the on screen model.
This scenario uses a complex AR app that allows a large variety of modifications to be made to the model, giving users the ability to customise the model with a wide variety of tools similar to those in many open-source 3D modelling apps. This customisation gives users opportunity to take the narrative of the book to places never imagined and thus extend the narrative.
With the app connecting to multiple different methods of 3D printing the highly customised models are able to be printed in any way the user decides; multi-material is used here to showcase the tactile nature of 3D printing. The inclusion of a model database gives users the opportunity to start building on other models, creating co-created models.
