Guide for increased accessibility through 3D models

The digital information used to create a 3D model can either be based on measurements from a physical object, or be created entirely digitally. A 3D model is a three-dimensional object produced in a digitally controlled process.

1. What is a 3D model?

A 3D model is a three-dimensional object produced in a digitally controlled process. 3D models are often referred to as prints, even though they can be made using other techniques, such as CNC ...

2. Tactile accessibility

The word tactile describes the transfer of information or sensations by touch. As many cultural heritage objects neither can nor may be touched, a 3D model can be a way of creating an accessible ...

3. Why 3D models for tactile accessibility?

3D models can increase the tactile accessibility of objects which cannot be touched, by offering a tactile representation of the object’s shape and volume. 3D models can also be used to produce ...

4. Supplementary information for tactile 3D models

While a 3D model can convey the form and volume of an object, it can never reproduce the materiality and function of the original object. 3D models therefore need to be supplemented with other ...

5. 3D models – opportunities and limitations

By themselves, or with the aid of other information carriers, printed 3D models can help increase the accessibility and understanding of cultural heritage objects. As a 3D model can never convey ...

6. 3D models and copies

A 3D model is a model; a representation, and not a copy. The function and materiality of the original must be conveyed through other media. However, 3D models can be used to both tactilely and ...

6. To keep in mind when making tactile 3D models

Certain objects and uses are better suited for 3D models than others. How do you tell which are best suited for 3D printing? Below are some examples of questions which can be used to assess an ...

7. 3D printing techniques

Additive manufacturing, often referred to as 3D printing, is a collective term for techniques used to manufacture objects in layers, based on a three-dimensional computer model. There are ...

8. Tactile images

Making two-dimensional images and photos tactilely accessible involves techniques such as swell-paper, collage pictures, and tactile photos. Tactile images should be produced by a designer with ...
