“…Printable Vitrolite can be annealed at 900 °C with no issue; however, in a previous study, we found that 3D‐printed and annealed Vitrolite has three times the dimensional error of green counterparts. [ 19 ]…”

“…However, prior work with Bison Vitrolite shows that the unfired, as-printed material exhibits adequate stiffness, chemical resistance, and outgassing for a vacuum analytical application. [19] In the same previous study, it was reported that only a portion of the platform of the Bison 1000 could be used to 3D print precision objects using Bison Vitrolite due to the high viscosity of the feedstock and the flexibility of the platform. [19] In this study, we found that by supporting the prints using posts at least 5 mm long (instead of printing the objects directly on top of the platform), and by changing the printable material to Universal Vitrolite, it is possible to use the full area of the platform to manufacture precision objects (Figure 6).…”

This study reports novel, compact, and additively manufactured quadrupole mass filters (QMFs) with adequate filtering performance for practical mass spectrometry applications. The QMFs are monolithically fabricated via vat photopolymerization of glass‐ceramic resin using 57 µm × 57 µm × 100 µm voxels, and selective electroless plating of nickel‐boron. Experimental characterization of QMF prototypes at 1.74 MHz using FC‐43 yields 131 Da peaks with 0.50 Da full width at half maximum (260 resolution), surpassing the resolution of reported miniaturized counterparts under similar conditions, and being on par with commercial, non‐miniaturized, heavier devices. The sensitivity of the 3D‐printed devices is estimated at 0.13 mA Torr−1 (comparable to that of optimized, commercial counterparts), while the devices attained up to 250 Da of mass range (limited by the driving electronics). The work is of interest to low‐cost, capable mass spectrometry, 3D‐printed instruments, and in‐space manufacturing of complex instrumentation.
