“…Additionally it is important to determine if any special surface cleaning or passivation steps are necessary before 3D-printed vacuum parts can be used. Currently the vacuum compatibility of 3D-printed materials has been shown for small components that sit inside a vacuum system, such as for Al-Si10-Mg, titanium and silver 21,26,37 and to make low vacuum KF vacuum parts 38 . However here we will show that 3D-printed parts can be used to construct high vacuum chambers, through acting as the vacuum wall and sealing to peripheral components, using indium sealing.…”

“…3D-printing has been used for a variety of applications ranging from fast compact laser shutters 17 to the realisation of complex magnetic field configurations 18,19 . The focus of 3D-printing technologies in regards to cold atom based sensors, thus far has been on magnetic field generation 20,21 , while little attention has been given to environmental isolation. Here we report on two demonstrators of crucial environmental isolation technologies needed for the realisation of portable and compact quantum technologies developed with 3D-printing, namely magnetic shielding and vacuum components.…”

Recent advances in the understanding and control of quantum technologies, such as those based on cold atoms, have resulted in devices with extraordinary metrological performance. To realise this potential outside of a lab environment the size, weight and power consumption need to be reduced. Here we demonstrate the use of laser powder bed fusion, an additive manufacturing technique, as a production technique relevant to the manufacture of quantum sensors. As a demonstration we have constructed two key components using additive manufacturing, namely magnetic shielding and vacuum chambers. The initial prototypes for magnetic shields show shielding factors within a factor of 3 of conventional approaches. The vacuum demonstrator device shows that 3D-printed titanium structures are suitable for use as vacuum chambers, with the test system reaching base pressures of 5 ± 0.5 × 10−10 mbar. These demonstrations show considerable promise for the use of additive manufacturing for cold atom based quantum technologies, in future enabling improved integrated structures, allowing for the reduction in size, weight and assembly complexity.
