The ICTP SciFabLab has hosted recently a project related to the challenge of making low-cost replicas of some mathematical surfaces that are part of the educational effort of IMAGINARY.ORG. Now the results are presented at a conference in Cape Town (South Africa), here you can find the presentations:

### “Low-cost 3D Printing: Maths you can touch”

*(duration: 60 min, 68 slides)*

IMAGINARY_1 (*PDF, 26 MB*)

IMAGINARY_1 (*PPTX, 345 MB* – **WARNING: big file size!**)

### “Replicating the IMAGINARY collection of math objects using low-cost 3D printers”

*(duration: 15 min, 18 slides)*

IMAGINARY_2 (PDF, 5 MB)
