Can you stack these gyroid modules into a pyramid? It can be a little tricky to get them to all line up properly, but you'll know you have it because the larger gyroid you create is highly symmetric, as evidenced by the gridwork of holes that run through it in many different directions.

Each module is a rhombic dodecahedron intersected with the gyroid, and hence this puzzle involves forming a face-centered cubic packing. Due to the way the module is oriented, it prints beautifully without support (better than the cubic original).

You can make this puzzle as large as you like; the more you print, the more you can stack.

The Gyroid is a periodic minimal surface discovered in the '70s. Everyone seems to love showing off their powder printers by making these, so I decided to see if it was possible to make one on a Makerbot. Turns out as long as the scale is small enough, these overhangs and bridges print quite well with no support.

I was printing these dualstrusion gyroids at the Seattle Mini Makerfaire on my new Replicator (they only take about 30 minutes). There's also a couple of single color versions included. You can stack these in all three dimensions to form a continuous surface.

This is a Minimal Surface i designed as a Pencils Holder.

This model is a subsequent design based upon the earlier posted model, 'Soap Bubble Chair':

My project that creates a chair from the shape of soap bubbles has recently been posted to Kickstarter. A soap bubble evenly distributes curvature throughout its shape, but at the same time equally distributes the structural forces as well. If you could harness this property for a structural system, you could use recycled materials and yield the same strength as high performance steel. This model depicts the chair's shape with actual soap bubbles, rather than in a solid print

Anyone who would like is welcome to print the file for themselves, but the model was created to be a reward for my kickstarter. Please take a look and contribute if you want to help out.

Using the same logic that created the soap bubble chair, I created a double sided vase whose shape could be formed with soap bubbles. A soap bubble evenly distributes curvature throughout its shape, but at the same time equally distributes the structural forces as well. If you could harness this property for a structural system, you could use recycled materials and yield the same strength as high performance steel.

I recently posted a Kickstarter campaign to support plan to build a real chair that uses these concepts. Please enjoy the soap bubble chair model posted earlier to Thingiverse, and I would encourage everyone who can to pledge a contribution on Kickstarter. My goal is to get 250 people to pledge $40.

In the coming days and weeks I'll be posting more things that use these shaping techniques, so check back and enjoy. Or just follow me on Twitter at @mSurfaces for the announcements.

This object, suggested for printing by Robert Jerrard, is a minimal surface in Minkowski space. It is scaled slightly to facilitate printing.

This is an example for surfcad, a surface oriented python cad library. The python code generates the STL. Read more at: christopherolah.wordpress.com/2011/07/16/surface-oriented-cad-math-telescopes/

surfcad can be found at github.com/colah/surfcad but is just in its infancy and subject to substantial API changes. Thus, it has also been attached...
