Nowadays, a lot of effort is given to making quantum technologies more usable for day-to-day life. This involves many aspects, such as developing quantum computers with a large number of qubits, creating quantum gates with high fidelity, and establishing a large-scale communication links with quantum repeaters. Miniaturizing such quantum devices remains nevertheless a highly relevant issue. For this, the 2-photon polymerization (2PP) based 3D printing comes in handy. In this talk, we present several miniature 3D printed optical and mechanical components, which enable the optical trapping of atoms and coupling quantum emitters and detectors to fibers or chips. These devices have an exceptionally compact footprint and a comparably high efficiency. With the ease of production of such components, 2PP can be scaled for the future requirements of highly compact and efficient quantum devices.
