N95 Respirator Limited Reuse

Posted on Updated on

What is the optimal way to prevent airborne transmission?

According to UNMC HEROES, “In this video, we demonstrate potential approaches for donning and doffing of an N95 filtering facepiece respirator is a Limited Reuse situation. This video was developed based on the CDC guidelines for NIOSH approved N95 respirators.”

3-D printing liquid metal with Vader Systems



University of Buffalo student Zack Vader has created a machine that prints three-dimensional objects using liquid metal.

According to Professor Edward P. Furlani  of Chemical and Biological Engineering and Electrical Engineering departments of University at Buffalo, Vader’s process uses a magnetic field to manipulate conductive fluids.  The magnetic field is used to create pressure for squeezing the liquid out of an ejector nozzle.

According to Furlani “It’s a transformative technology.  It’s very exciting interdisciplinary engineering. I think its application base will continue to broaden and expand for the foreseeable future.”

According to Chi Zhou, Assistant Professor at University of Buffalo, “I can see at this stage that it can complement traditional metal printing, but later, maybe 10 years later, it can dominate the metal printing market because it can print better quality, cheaper and faster.”

Vader’s 3-D printer can be used in future for making custom knee and hip replacements.

BUFFALO, N.Y. — A father and son team in the START-UP NY program have invented a liquid metal printing machine that could represent a significant transformation in manufacturing. A breakthrough idea five years ago by former University at Buffalo student Zack Vader, then 19, has created a machine that prints three-dimensional objects using liquid metal.
