Architected Skull (Hex Honeycomb)

This skull is part of a series that demonstrates three of the architecting features in nTopology software.

See here for video: https://youtu.be/ZX4rk4VM46U 

In this series, the Gyroid Triply Periodic Minimal Surface, Face Centered Cubic Lattice and Hexagonal Honeycomb unit cells have been applied to a conformal cell map derived from the outer surface of the skull. Using this technique allows the structures to follow the bone contours and converge on the front and back of the skull.

Brain Breaker Blocks

If you’re bored of Lego, this 3D printed self-interlocking construction block will break your brain. It takes minutes to print, months to figure out!

See here for video for demonstrates of the concepts outlined below: https://youtu.be/j10wzy0qGOg 

Officially known as an “SL Block,” this octocube shape is part of a family of “topologically interlocking assemblies,” that is, shapes that hold together without the use of connectors or adhesives to form self-interlocking structures. Self-interlocking structures have interesting architectural and engineering applications.

A ends of a single “SL” block resemble an “S” and an “L.”. In assembly, SL blocks always occur in pairs, called a “Conjugate Pair.” In the pictures and video, conjugate pairs are shown with one white and one black piece.

Conjugate pairs lock together in six different ways, called “engagements,” to form “SL Strands.” Each type of engagement adds a unique translation or rotation to the SL Strand. The six types of engagements are denoted as “h,” “t,” “s,” “d,” “a” and “y.”

Using this system, the SL strands can be represented as strings consisting of six letters that stand for
the six types of engagements.


The first example in the video is an “h4” SL Strand. “h” engagements are straight with no rotations or translations, so the strand is straight.

The next example is an “a4” SL Strand. “a” engagements create a 90 degree rotation but no translations, so the “a4” strand makes a closed, cube-shaped structure.

The final examples in the videos show more complicated “(as2)4” and “(dth)4” strands. These modules can then be connected to form larger and increasingly complex self-interlocking structures.
