PROVO, Utah — In celebration of Brigham Young University’s 150th anniversary, BYU electrical engineering professor Greg Nordin and student Callum Galloway created 150 microscopic 3D-printed replicas of existing temples.

These temples were all completed on July 31, 2024, in anticipation for the anniversary. The 150 temples were laid on a 12-by-19-millimeter microchip in a 10-by-15 grid. Each temple had measurements of about 1-by-0.5-by-0.3 millimeters, about the size of a poppy seed.

“When we heard about the sesquicentennial ‘Beacons of Light’ celebration, we thought, can we use this superhigh-resolution 3D-printing capability that we’ve developed to create something special?” said Nordin in a BYU news release.
