What is Giulia?

Giulia is a downloadable and 3D-printable learning set designed primarily for visually impaired people of all ages, as well as for anyone interested in tactile and spatial learning tools.

What does Giulia do?

Giulia supports the understanding of fundamental concepts related to Cartesian space, algebraic number theory, and algebraic solids through physical, tactile interaction.

Do I have to pay for Giulia?

The .STL models can be downloaded free of charge.
The intention of the creators is to keep Giulia accessible over time.
Please note that physical production (printing, materials, labour) may involve costs when carried out by third parties.

I cannot or do not want to print. Can Giulia be produced for me?

Production may be possible upon request and is subject to prior evaluation.
Educational and non-commercial contexts may be given priority.

AUTHORS

Who are Giulia’s authors?
Giulia was created by Stefano and Eleonora Vuga, designers and educators, with the valuable contribution of mathematics teachers from a certified institute for visually impaired children.

Giulia is the result of ongoing research that was accepted and presented for the first time during a Poster Session at the MIT LINC Conference, held on June 18th, 2019, in Cambridge (MA), USA.
You can read the full abstract here. (Release date: June 18th, 2019).

DISCLAIMER

(for users and trusted 3D printing centers)

Giulia requires a high level of printing precision.
The use of PLA is recommended.

Due to the many variables involved in 3D printing — including machinery, materials, calibration, and execution quality — it is not possible to account for every scenario. For this reason, it is strongly recommended to initially print no more than two samples per component, test the joints, and, if necessary, request minor local adjustments from your trusted 3D printing center before proceeding further.

Sharing technical feedback within closed professional groups and networks is considered good practice. You are also welcome to share your experience with us, should you wish to do so.

Once the files are downloaded, please ensure that your software is scaling the objects correctly.
For the “Unit” cube, the correct dimensions are:

  • 30.25 × 30.25 × 30.25 mm

  • 1.1909449 × 1.1909449 × 1.1909449 inches

If necessary, use this object as a reference and scale all other components accordingly.

Where component colors are not specified, use a uniform color for all elements. Neutral tones such as grey or white are suitable.
The use of specific colors for certain components may be helpful for users who are not fully visually impaired.

This is the first public release (v1.0) of the project.
This page and the downloadable models will be updated and refined over time.
