3D printing sensors that test water quality

According to the Max's advisory, researchers at UBC's Okanagan campus have designed a 3D printed microdisplay that monitors the quality of drinking water in real time and prevents waterborne infections.

Professor Mina Hoorfar, dean of the school's engineering school, points out that the study shows that the miniaturized water sensors they produce are cheaper to produce and operate continuously and at any node in the water system.

Hoorfar said that "current water safety practices include only regular manual tests that limit the sampling frequency and increase the likelihood of outbreaks.Traditional water sensors are expensive and unreliable throughout the water system."

So far, the device created at Hoorfar's Advanced Thermo-Fluidic Laboratory at the University of British Columbia-Okanagan has proven to be reliable and robust enough to provide accurate readings regardless of water pressure or temperature. The sensor supports wireless capabilities and can work independently and send data reports back to the test station, even if one of the sensors stops working and does not implicate the entire system. And because they use 3D Printing technology, so fast, cheap and easy to manufacture features.

Professor Hoorfar adds, "This highly portable sensor system continuously measures various water quality parameters such as turbidity, pH, conductivity, temperature and residual chlorine and transmits the data back to the central system via wireless transmission. Is a unique and effective technology that revolutionizes the water industry. "

While many urban decontamination units are equipped with real-time monitoring sensors, they are upstream of the water system. However, Hoorfar notes that the pressure delivered to the customer's home is much higher than the pressure that most sensors can handle. The new sensor can be placed in the customer's home to provide direct and precise protection of domestic water.

This sensor avoids the tragedy caused by water quality problems. Seventeen years ago, drinking water contaminated with E. coli in Lake Ontario, Walkerton, Canada, left four people dead and hundreds of people sick.

Hoorfar said, "Even though most water-related diseases occur in low- and middle-income countries, even developed countries like Canada are thinking of water safety because of the water quality in Walkerton Town To be preventable, it is only necessary to monitor frequently or early detection of the pathogen that causes the outbreak. "

Die Casting is a manufacturing process in which molten metal is injected under pressure into a hardened steel mold or die.
Molds are usually water-cooled.
Then the mold is opened and the die-cast (thousands of parts per day, sometimes just a few hundred) pops out.
Once the tool is paid for, die-casting is a very cheap process for making aluminum parts.
