Did you 3D print this model?

3D model description

These models are examples of surfaces that have a nonremovable discontinuity at the origin. They are examples I use in one of my lessons for my Multivariable Calculus class.

Infinity Surface has the equation z = y/(x^2 + y^2).
At (0,0) you can find limits of 0, infinity, and negative infinity.

Pinched Surface has the equation z = 2xy/(x^2 + y^2).
At (0,0) you can find limits of 0, 1 and -1.

Created with Mathematica.

3D printing settings

Infinity Surface approximately 102 x 102 x 102 mm. Printed with supports and raft. See photos.

Pinched Surface approximately 102 x 102 x 52 mm. Printed with supports and raft.

I am a high school math teacher and 3D printing hobbyist. I have been 3D printing since 2017 and enjoy making things for my classes and my own children and home in San Diego, California, USA.

I have a 3D printing sub-site abbymath.com/3DPrinting. See my video on YouTube and my user story written and published by Simplify3D. I design with Mathematica, CorelDRAW, Fusion 360, and Tinkercad. I love my MakerGear M3-ID Rev. 1 and I have a Monoprice Mini as well.
