Title:: From artefacts to 3D prints: Innovative workshops at the museum

19 N°IV 2024 MuseoMag 3D PRINTING them. The aim of the workshops is threefold: learning about 3D modelling and printing, using these tech- nologies in a museum context and learning about archaeology and numismatics. With their newly ac- quired skills and some inspiration from our collection, participants can create their own “Plastic Age” ob- jects with a special software and our new 3D printers. CREATING 3D MODELS: FROM CONCEPT TO PRINT But how do you print an object? Where does the model come from? The printers are designed to print three-dimensional objects. They have an x, y, and z axis, allowing the nozzle, where the melted material called filament is pushed through, to move around. The filament is laid down on a printing platform, where the nozzle forms the object. The objects they print start as digital files. Models can be obtained in various ways. They can be digitally designed using a CAD (Computer-Aided Design) programme, or they can be photogrammetrically, computed tomogra- phy-based or laser-scanned objects converted into a 3D model. The model is then loaded into a slicer, a programme that, as the name suggests, slices the object into different layers. Think of it like a layered cake. While the outside appears smooth, the inside consists of various layers of geometrical shapes (e.g., honey- comb), giving the object structure and strength. The slicer provides the printer with the instructions needed to build the object, which the printer then constructs from bottom to top, layer by layer. INNOVATIVE USES OF 3D PRINTING IN MUSEUMS When not used in workshops, in-house 3D printers can also be useful in other areas of museum work. They can, for example, be used to print touchable copies of the objects on display and replace them if necessary. Although different to the touch, 3D-printed copies break down the barrier between the object and the visitor. These copies can be beneficial for visually impaired people, allowing them to experience archaeology, history and art. Objects can be scaled up or down, enlarging small coins or downsizing large buildings for people to touch. The printers can also be used by our craftspeople to produce certain parts they need, rather than ordering and buying them. In the long term, setting up a makerspace for public use and offering training on how to use the printers may be possible.
