Visualizing Mathematics with 3D Printing – New Book by Mathematical Artist Henry Segerman

In 2013, I collaborated with Henry Segerman to create a first of its kind collection of 3D Printed Mobiles. Outside of being Assistant Professor in the Department of Mathematics at Oklahoma State University, Henry has since established himself as one of the leading figures in the new world of math and 3D printing. This month he has a new book out titled Visualizing Mathematics with 3D Printing in which he takes readers on a fascinating tour of two-, three-, and four-dimensional mathematics, exploring Euclidean and non-Euclidean geometries, symmetry, knots, tilings, and soap films.

The book includes more than 100 color photographs of 3D printed models, and has a sister website that features virtual three-dimensional versions of the models for readers to explore.

Also take a look at Henry’s amazing 3D Printed Mathematical Art.

Balance – Suspension Points and the Centers of Mass in Abstract Mobile Sculptures

A custom designed mobile for a private residence in Montana in progress:

For an element (shape) to be able to balance, the suspension point needs to be above the center of mass. In addition to this requirement, when the center of mass is lower (farther away from the suspension point), the balance will be more stable. Vice versa, when the center of mass is higher (closer to the suspension point), the balance will be more fragile (the element is more likely to overturn):

Obviously within a mobile, an element might have the weight of several elements that are in the lower part of the mobile attached to it, which lowers the center of of mass. A good example of this can be seen in a large site-specific mobile I was working on for a three story light shaft in Chicago last year:

In some cases, it might be necessary to raise the suspension point with the help of an extension:

Hanging and Standing Mobiles Exhibit – Call to Artists

Call to artists for The Mobile: Composition in Motion, an exhibit of hanging and standing mobiles at The Carrack in Durham, NC.

Artists working in any medium, regardless of mobile-making experience (learn to make mobiles), are invited to try their hand at creating innovative pieces that are set into motion through air current. Unique interpretations of mobiles as sculpture in motion are encouraged. Challenge what’s possible in terms of form, materials, construction, movement and scale.

The exhibit will also provide information that helps visitors understand the principles that commonly govern mobile construction and ways in which the exhibiting artists may have adhered to or defied those principles.

There is no submission fee for this juried exhibit and you can enter as many pieces as you like. The Carrack is a zero-commission art space and therefore 100% of any sale proceeds go directly to the artist.

The submission deadline is August 7th 2016. The exhibit opens November 9th 2016. Please see for more details, and follow up-to-date information on Facebook and Instagram.

New Calder Exhibit “Motion Lab” at SFMoMA – Installation of Large Mobile in Atrium

A new Alexander Calder exhibit titled Motion Lab at The San Francisco Museum of Modern Art opened this past Saturday and will run until Sept 10 2017. It traces Calder’s explorations of motion from the late 1920s to the late 1960s.

Photos of Rigger Lawrence LaBianca lowering from the SFMOMA sky bridge to finish installing Calder’s 27-foot Untitled (1963) mobile in the Evelyn and Walter Haas, Jr. Atrium:

There’s also a video of the installation by the San Francisco Chronicle.

Technical Behind-the-Scenes Aspects of Designing, Making and Installing a Large Custom Mobile

Some of the technical (“behind the scenes”) aspects of designing, making and installing a large custom mobile.

Proposing a variety of designs to the client (see the full render designs).

Creating the 3d model of the space and the sculpture. Making adjustments to ensure that as the kinetic sculpture rotates and moves with the air currents, it will always remain out of reach from the various floors.

Establishing the engineering data.

Preparing the file containing the shapes (Calder style/inspired with this specific design chosen by the client) for laser cutting.

Confirming that all the balance points have been calculated correctly, in other words, reality needs to confirm theory (with the help of a crane).

Keeping it safe from vertical shocks caused by bumps and potholes as it’s transported (in this case) 500 miles / 800 km across the Appalachian Mountains.

Planning the layout of the mobile parts on the installation lift, so the overall 33 foot sculpture can be raised through the 22 by 15 foot opening in the atrium from the ground floor to the upper floors.
