You (Honk) @ Waterloo Day: Future students and their families aren't the only ones touring campus these days, as this photograph taken by Admissions Officer Eric Jardin clearly demonstrates.

3D printing you can sink your teeth into

Leave it to a team of fourth-year Waterloo engineering students to trump news of NASA's quest for a 3D printed pizza using protein harvested from such sources as insects and algae by heading in an altogether tastier direction, with chocolate as their building blocks.

Mechatronics engineering students Andy Vopni, Brian Luptak, Benjamin Cousins, and Nima Majidifar designed and built a Selective Laser Sintering (SLS) 3D printer as their fourth-year design project. The printer can use standard thermo-plastic powder to build three-dimensional objects from digital models, but the team chose to place a special emphasis on the use of chocolate powder as their primary print material.

The team demonstrated their 3D printer at the mechatronics engineering design symposium back in March, and most recently this week at the OCE Discovery Conference 2013 in Toronto. The team's printer was also featured recently in a Business News Network video shot at the OCE conference.

The team's device is what's known as an additive printer, which builds an object layer by layer by laying down a dusting of chocolate powder that is then heated—sintered—by a laser, leaving behind a solid mass.

Above, a video taken available on the team's website shows a time-lapse sequence of the team's printer building a delicious, if slightly off-model, three-dimensional University of Waterloo logo. We hope to see such treats available in the Waterloo Store in the near future.
