Atom chip technologies have shown excellent promise as a base in order to probe the physics of quantum gases, but also for the implementation of quantum based sensors in gravitometry [e.g. EU-funded iSense project], nanoTesla sensitive magnetic devices with micrometer resolution and optical cloud based microscopy. Such chips are inherently ultra-high vacuum (UHV) compatible, necessary for long lifetime atom traps. Further these traps rely on highly power consuming and planar "under-structures", required to form and cool the magneto-optical traps (MOT) on which atom-chip based experiments depend; not to mention often cumbersome experimental baggage.
We introduce a different approach, addressing the challenges started above: additive manufacturing (3D Printing). Using an additive process where successive layers of material are laid down allows for almost arbitrary structures to be created; coupling this with modern optimization algorithms to optimize magnetic trapping in terms of power consumption, heat generation, structure robustness and size would substantially improve overall device performance. 3D Printing offers the possibility of integrating electronic, optical or vacuum components, potentially allowing the formation of a fully integrated atom chip device.
