3D printing typically involves depositing layers of molten plastic, laser-melting powdered metal, or using UV light to harden gelatinous resin. A new technique takes yet another approach, however, by ...

Researchers describe a new platform technology called direct sound printing (DSP), which uses soundwaves to produce new objects. The paper explains show how focused ultrasound waves can be used to ...

Most 3D printing methods currently in use rely either on photo (light)- or thermo (heat)-activated reactions to achieve precise manipulation of polymers. The development of a new platform technology ...

Imagine that doctors could precisely print miniature capsules capable of delivering cells needed for tissue repair exactly where they are needed inside a beating heart. A team of scientists led by ...

A platform technology created by a team of Concordia researchers has been named one of the most significant scientific breakthroughs of 2022 by Québec Science, the province’s leading science magazine.

Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of ...

This thesis focuses on the design and implementation of a system for monitoring quality during the 3D printing of concrete using computer vision methods and laser triangulation. The goal is to measure ...

Mechanical engineers Shervin Foroughi and Mohsen Habibi were painstakingly maneuvering a tiny ultrasound wand over a pool of liquid when they first saw an icicle shape emerge and solidify. The pair ...

Abstract: A computational simulation is carried out with the Carreau model to explore the non-Newtonian behavior of ink for gravure-offset printing. The volume of fluid (VOF) model is adopted to ...
