3D Printed Cryogenic Components for a Dynamic Nuclear Polarization Target

Recent advances in additive manufacturing allow for rapid development and prototyping of equipment. We have developed cryogenically stable components that survived multiple 1K temperature cycling using readily available 3D printing materials. We have also developed a method to print using flouroplastics, with a focus on Kel-F which is traditionally used in DNP targets due to their cryogenic properties, transparency to microwaves, and lack of free protons. These advances will be discussed, as well as recent exploration of 3D printing optical microwave components, 3D printing of scintillators, and 3D printing SRF cavities.
