Structure & Reflectance

Like people, materials have a complex structure that results from their history—the sequence of processes that have shaped their constituent parts—and which underpins their differences. This structure is, in materials as well as in people, often masked by an exterior façade which reveals little about any underlying quality. Only in extreme environments or situations this hidden structure may reveal itself and become visible through reflections.


 The Structure & Reflectance cube is a material representation of human’s, complex structure, which is embodied in a block of metal consisting of two crystals with distinct reflectivity and complementary shape. The crystals—ingrained in the cube via additive manufacturing technology—are revealed to the naked eye through the action of a corrosive agent and are highlighted by differently oriented light sources. The resulting optical contrast on the cube surface generates an intricate geometry reflecting the duality of man, the complexity of hidden thought and expressed emotion.


 The concept of duality illustrated by the Structure & Reflectance cube can easily be linked to the Moon. One side of it always remains in plain sight, while the other has remained hidden to mankind for centuries; until space travel finally allowed us to gaze upon it. Moreover, the portion of the visible side of the Moon which is bright depends on the Moon’s position relative to the Earth and the Sun. What we see is a function of our viewpoint. In the Structure & Reflectance cube this concept is expressed by the changing reflectance of the two crystals, which vary with the observer’s viewing angle. Such a detailed level of control over the crystal structure of solids may not be achieved but with additive manufacturing technologies.


In this work, we used laser powder bed fusion technology—a metal additive manufacturing process—to create four different symbols on four faces of the Structure & Reflectance cube. Each symbol portrays our quests to discover the secrets of the Universe and—fused together into a single cube—embody the unity of mankind, which transcends our differences in culture, religion, or social status.


  1.   The first cube face is divided into two triangles and depicts the two faces of the moon, one visible to us from earth and the other hidden from our view.

  2.   The second cube face has two spiraling windmill forms, one clockwise and the other counterclockwise, which represent our existence, energy, and time.

  3.   The third cube face is a labyrinth form of nested squares which represents the layers that we—as space explorers—are unraveling to discover the enigma of the universe. 

  4.   The fourth cube face reflects the spiraling form of our DNA that makes each of us unique; a            shape that is also reflected in the form of our galaxy.



The everlasting nature of metal, the variety of crystal shapes, the complexity of material structure, the unifying message of an integrated world, and the marriage between art and technology make the “Structure & Reflectance” cube a quintessential signature of mankind to be displayed on the Moon.


Every human endeavor is a collection of continued collaboration and development layered onto the discoveries, inventions, and innovations of the past. Our every perception, analysis, and thought are a reflection of these myriad influences from our surroundings and from the universe. 


This artwork embodies the relationship between structure and reflectance. The structure of our changing viewpoints, perception of colors, and space are continually being explored and reimagined by artists, scientists, religious and cultural groups. This is reflected in an integrated world of collaboration, communication and interaction that are making it possible to explore the real, the imagined and the unknown. Space could be our future home.
