While 3D printing is often applied to heat exchangers as a means of improving performance through geometry, there is another compelling reason to print these devices: material freedom. A project undertaken at Carnegie Mellon University sought to demonstrate the viability of additive manufacturing for producing heat exchangers used by the solar energy industry, which frequently operate at temperatures above 850ºC and pressures as high as 200 atmospheres. In this episode, we speak with Dr. Tony Rollett about demonstrator parts developed at CMU and produced through laser powder bed fusion from Haynes 230 and 282, two nickel-based alloys with creep resistance suitable to this application. | This episode of The Cool Parts Show is sponsored by Carpenter Additive
