Hey guys, I'm working on a new tech start-up called ThermoChrome. We have created several types of resins for 3D printing which can change color at different temperatures. Since the temperature threshold can be customized, products made with the resin can have applications in food safety, temperature regulation in buildings to save energy, and heat stroke alert devices. We have also created an app which can be used to report the temperature of the resin based on its color.
