3D models and 3D printing

We digitise the holdings of the Collection of Classical Antiquities as part of a variety of projects. Through seminars and practical courses, students have the opportunity to participate actively in this process, developing digital skills and gaining valuable experience for their future careers. Digitisation encompasses a wide range of activities, from basic photography to the creation of complex 3D models. These models are used not only in virtual environments but also, for example, as 3D prints in “portable museums” for schools. Learn more about the individual stages of the process — from taking a photograph to producing the final 3D model — here.

 

 

 

 

 

The process begins with the digital recording of a collection object. This can be carried out either by photographing the object from multiple angles or by using a laser scanner, which automatically generates three-dimensional data. The resulting data can then be imported into 3D software for further processing. When photography is used, photogrammetry techniques generate three-dimensional models from two-dimensional images. To produce a high-quality model suitable for detailed 3D printing, both the number and resolution of the photographs are essential — the greater the quantity and quality of the images, the more detailed the final model will be.

 

 

 

 

 

Photogrammetry is a technique used to create three-dimensional models from multiple overlapping photographs of an object taken from different angles. During this process, specialised software identifies corresponding reference points within the images and uses them to reconstruct the object’s three-dimensional form. The resulting model can then be further edited, scaled, printed, or even animated.

 

 

 

 

 

 

 

3D software suites not only enable the creation of polygon meshes and the adjustment of a model’s resolution and scale, but also support the entire 3D production pipeline, including modelling, rigging, animation, simulation, rendering, compositing, motion tracking, and video editing.

 

 

 

 

 

3D printing refers to a range of manufacturing processes in which liquid or solid materials (such as filament) are deposited layer by layer onto a build plate to create three-dimensional objects. This additive process is computer-controlled and relies on physical or chemical melting and curing techniques based on predefined dimensions and forms. Depending on the size of the model and the printing technology used, production times may range from a few minutes to several hours.

 

 

 

 

 

 

The finished object is a physical replica that can be reproduced as needed and employed in a variety of educational settings. Its tactile character makes it especially suitable for repeated use in “portable museums.”
