For 3D printing nerds: Vat photopolymerization was carried out using a Bison 1000 DLP printer (Tethon 3D, Omaha, NE, USA) with a light engine composed of a 1920 × 1080 array of 405 nm UV LED pixels of 57 µm in size. The dielectric structures were printed in 100 µm slices. The vat of the Bison 1000 heats up the resin to improve the adhesion of the printed part to the platform and to reduce the viscosity of the resin during printing. The printer is installed inside a custom, filtered HEPA cabinet to keep a clean and regulated working environment. The dielectric parts were made with Universal Vitrolite (Tethon 3D, Omaha, NE, USA)—a photocurable glass-ceramic resin heavily doped with silica microparticles. A paragraph down: Following the printing process (Figure 8a), the fabricated parts are selectively masked using Procoat maskant lacquer (Maskcoat, West Monroe, LA, USA) to achieve galvanic isolation between the electrode surfaces From: https://onlinelibrary.wiley.com/doi/10.1002/advs.202307665 https://onlinelibrary.wiley.com/doi/10.1002/advs.202307665 Edit: added additonal paragraph
