Engineers at BYU have been honing their 3D printing skills — their latest project is creating microscopic temples to commemorate the school’s 150th anniversary.

While 3D-printed replicas of temples of The Church of Jesus Christ of Latter-day Saints are nothing new, these are unique in that they are all smaller than a grain of rice.

Electrical engineering professor Greg Nordin and student Callum Galloway spearheaded the project, in which they made 150 replicas of existing Latter-day Saint temples, all of which fit on a 12-by-19 millimeter microchip.

Nordin has been researching micro and nano-fabrication processes for years to create devices that are microscopic in scale and can be used in a variety of applications. Typically, his lab focuses on creating a “lab on a chip” device, where a
