3D printing is the process of creating a three-dimensional object using a machine that builds it one layer at a time. The fact is that 3D printing has been around for a while, but affordable machines that you could build at home are a fairly new phenomenon. One of the reasons you may have heard about 3D printing recently is because of its utility during the COVID-19 pandemic. Makers were creating printable masks, critical medical spares and a lot of innovative solutions for patients and frontline workers.

One such innovator, Kaushik Mudda from Ethereal Machines has been creating a lifesaving splitter that multiplies the capacity of a ventilator, allowing two patients to use a single ventilator.
