Dissolvable 3D-printed templates can be used to produce NMR transceiver coils of a particular geometry. Wire coils such as variable-pitch solenoids are wound on dissolvable 3D printed forms, which are then dissolved away in solvent. The use of high-temperature resin, with the appropriate solvent, enables annealing to be performed before dissolving the template. This approach allows facile, reproducible production of coils even in the hands of inexperienced researchers. The ability to design a coil and its corresponding template in a CAD program, simulate the magnetic and electric fields in its vicinity, print out the template, and make it greatly facilitates the process of testing coil designs and sharing successful ones with other laboratories. This approach can also be used to enable production of more complicated designs that are not easily made with hand winding. I will describe strategies for using 3D printed coil forms in conjunction with simulation-based optimization to produce high-homogeneity rf coils. Simulations and experimental (benchtop and NMR) measurements using different resonator designs will be discussed, along with future applications to biomolecular NMR.
